00:00:02
the topic will be 28
00:00:04
this is the cardiac cycle the cardiac cycle and in
00:00:07
turn James one system Dias there we will
00:00:17
first figure out about the sister then our
00:00:21
radio first the track what processes are
00:00:24
happening what all the forces so the
00:00:27
remedy itself consists of 2 phases
00:00:29
this is called voltage and there is
00:00:38
called
00:00:39
exile, which means the phase of tension and the phase of
00:00:46
which
00:00:47
expulsion is its turn the phase of tension
00:00:50
it is divided into two periods, these are wasps and
00:00:55
if you write here from synchronously and
00:00:59
contraction and isometric contraction,
00:01:01
asynchronous contractions and
00:01:04
isometric contraction of expulsion
00:01:07
are also fast and slow, that is,
00:01:14
fast and what is slow spirko
00:01:17
as in the heart what happens during an
00:01:20
asynchronous contraction with an
00:01:23
isometric contraction and in both that
00:01:27
is, from the fast and slow what is expelled
00:01:30
means this will be what we will have what the heart
00:01:36
will be like a bicuspid this is a
00:01:39
tricuspid trials 2 this will be
00:01:44
the oorta this is the pulmonary trunk this is the aorta
00:01:49
this is the league of chinois, then this is the aorta
00:01:52
and this is the pulmonary trunk of the internal between the
00:01:56
ventricles there is what about the lunar valves,
00:01:59
this is called what about the lunar valve
00:02:03
and now to answer this question,
00:02:06
that is, what to answer the question of what
00:02:11
what comes from synchronously
00:02:13
isometric and expulsion you need to
00:02:16
know 5 question and if you
00:02:20
answered each of these 5 questions you
00:02:23
will understand the essence of it look at the first question what is this something
00:02:27
when they show in your drawing
00:02:32
what it is what it is what it looks like
00:02:35
asynchronous contraction for metric
00:02:37
contraction and the phase of which is expelled the second
00:02:40
state of the valves of the
00:02:45
valves the state of the valves, that is, with
00:02:51
quietness and contraction of the valves opening
00:02:53
or semi on such that is, the state of the
00:02:55
valves, some valves should be
00:02:58
open and some should be
00:02:59
closed, the third physiological value is a
00:03:05
logical value or some of it
00:03:10
as a physiological role is a function, that is, the
00:03:12
values ​​are somehow not maiden what's
00:03:15
going on here, what's going on here, what's going on here 4 this is the
00:03:18
duration duration
00:03:23
or time or intermediate
00:03:26
that is, this and the heel this is the record
00:03:33
how can you determine them this
00:03:37
record we'll just put it so that they
00:03:40
growl in the tests but
00:03:43
we'll go through the photo in more detail about the record g and
00:03:46
Sergey that is, a complete cardiogram and from the
00:03:50
film gram that is, we will speak
00:03:52
from synchronously and the contraction is recorded
00:03:55
this
00:03:56
and the VKG effect that is, with synchronous
00:04:00
recording
00:04:01
ege-gay fixes, isometric crumbling
00:04:03
with synchronous recording river g and yourself, you
00:04:06
will just study it like that, but remember
00:04:09
so that the test can decide and when we are pros ggg
00:04:13
we will burn
00:04:14
you stick it there you will understand it means for each
00:04:17
this you must answer 5 questions what
00:04:19
will answer then you will already understand what is
00:04:22
going on and now we will go through the
00:04:24
first one in order this is how we go from synchronously and
00:04:28
abbreviation during asynchronous contractions
00:04:30
look semilunar valves are closed
00:04:36
leaf valves open let's
00:04:38
first what are you burning
00:04:41
this figure reflects asynchronous
00:04:43
contractions the second state of the valve you are
00:04:47
burning semilunar valves are closed
00:04:50
leaf valves are open third question
00:04:54
physiological significance
00:04:56
look here there is blood yes but since
00:05:01
the pressure here is not increased how
00:05:04
will you understand that here the pressure is not increased
00:05:07
since the flap valves are open
00:05:09
istituto the pressure would be greater if it
00:05:12
were in the back but since there is no
00:05:15
more pressure here so the flap open
00:05:18
here comes from synchronous
00:05:20
excitation of the walls of the stomach are not the same,
00:05:25
that is, without the shape changing but the pressure
00:05:28
of which does not increase that is, how do you
00:05:30
answer physiologically very much and you
00:05:33
say
00:05:34
with asynchronous contraction that is, in the
00:05:37
ventricles it occurs asynchronously and
00:05:39
contractions here the shape of the ventricles
00:05:41
changes but the pressure of which does not
00:05:44
increase 4
00:05:45
viewers how long does it last you
00:05:48
burn 0 04 00 5 seconds 0 04 00 5 seconds
00:05:55
and 5 this is a recording, a recording, what can we
00:05:58
say, this is a synchronous recording, etc. and
00:06:02
so on.
00:06:04
d we so when the cardiogram field will
00:06:07
go through all this you are there and you will see 2 2
00:06:12
isometric contraction
00:06:13
now the first question is what does it look like
00:06:16
on this diagram is reflected what
00:06:18
isometric contraction is reflected in the second
00:06:20
state of the valves you are burning there is a courtyard and the
00:06:25
semilunar valves are closed from the quart and the
00:06:28
valves are closed there is blood here now the
00:06:33
question is why these valves
00:06:36
closed, we are talking because here
00:06:39
the pressure increases in the ventricles
00:06:41
the pressure increases
00:06:43
if it is the right ventricle without
00:06:46
pressure increases to 77 excuse me to
00:06:52
10 15 millimeters of mercury and here it is
00:06:56
7 780 so why are these valves
00:07:00
closed and why are these valves
00:07:03
closed if your question will
00:07:05
look like if the pressure in the aorta is 100
00:07:08
and the pressure in the pulmonary trunk is 20,
00:07:13
so seventy to eighty is not
00:07:17
enough force to come out, for the blood to come out, it
00:07:19
needs more than a hundred, there should be
00:07:22
120 130 140 for it to come out,
00:07:25
so this pressure closes these
00:07:27
valves valves and the pressure of
00:07:30
the main vessels close the
00:07:32
vacuum valve
00:07:33
so the physiological meaning means the
00:07:36
physiological initial you are burning the
00:07:37
pressure in the ventricles increases in the
00:07:40
right ventricle then ten to fifteen
00:07:42
miters here on the very left live up to 70 80
00:07:46
meters it has become difficult but here you can’t miss the expulsion
00:07:48
now the expulsion phase the expulsion phase
00:07:53
first the question is what is it you are burning phase
00:07:56
expel state of the valves burn out
00:08:01
leaflet closed semilunar open and
00:08:05
here is what happens before the
00:08:07
expulsion phase the expulsion phase there are two
00:08:13
types fast and slow fast that is
00:08:17
fast expulsion the pressure in the
00:08:19
ventricles continues to increase that is
00:08:23
here if here the pressure in the
00:08:25
pulmonary trunk was 20 to know for the
00:08:28
expulsion to happen it is necessary what 2530
00:08:31
means and here the pressure how much it cost
00:08:34
means here it is necessary 130 it cost 40
00:08:39
therefore with rapid expulsion the pressure
00:08:42
continues to increase in the ventricles
00:08:45
on the left they live will give 130 140 it increases
00:08:48
especially difficult for them and in the right they live 25-30
00:08:52
and as a result it happens quickly
00:08:55
expulsion is slow and expulsion is slow and
00:08:57
expulsion occurs through gifts of pressure in the
00:09:00
ventricles and in the great
00:09:03
vessels from here we can say from
00:09:05
synchronous
00:09:06
and isometric contraction they
00:09:08
prepare the ventricle for the
00:09:10
expulsion phase to make it easier to remember look
00:09:13
at the start attention march to the start attention
00:09:17
march
00:09:18
therefore asynchronously isometric
00:09:20
contraction is like at the start, attention, the
00:09:23
expulsion will be what is your so over everyone,
00:09:28
this is what we answered the 5th question and
00:09:30
the duration of it is how long is the expulsion phase
00:09:33
you are burning 026
00:09:37
029
00:09:39
026 0 29 seconds now records where
00:09:44
it happens you only speak to us of the film
00:09:47
gramme szege recording us because on the verge of
00:09:50
isometric contractions duration
00:09:52
how long are you burning 00 2003 se que records
00:09:59
where is happening look like figs and g.i.
00:10:04
tags
00:10:05
that is, synchronous recording in which and for yourself
00:10:08
you have more questions about the
00:10:11
voltage phase now question 5 but these 5
00:10:15
questions for the voltage phase
00:10:18
first there are if you know these two and
00:10:21
it’s already easier
00:10:22
that this is well the voltage phase the
00:10:26
voltage phase both the whole garden the state of
00:10:29
the valves you say the composition of the state of the
00:10:31
clan during the voltage phase depends on the
00:10:34
period during the voltage phase the
00:10:37
semilunar valves are always closed
00:10:39
but during the voltage phase they are not always closed
00:10:42
which
00:10:43
leaf valve it depends on what
00:10:46
period of action in your tests the
00:10:48
prophase voltage will be constantly closed the
00:10:51
leaf valve you are not burning
00:10:53
but the leaflet valves can close,
00:10:55
you are burning yes it depends on what
00:10:58
period the physiological meaning you
00:11:01
are talking about physiothe phase of tension
00:11:03
prepares the ventricle for the phrase of what
00:11:06
expulsion duration look there is this
00:11:10
003 if this 005 means 00 3 + 0 05 this
00:11:15
will be zero zero eight seconds that's
00:11:18
long and 5 this recording we are watching
00:11:21
asynchronous these gays and kegs of
00:11:23
isometric fics gay saga means the
00:11:26
beginning and end of perina
00:11:28
means it will be both kg and ourselves this is us on a
00:11:33
synchronous recording and spearmen g c g or in
00:11:36
another way the cardiogram field is
00:11:38
called this we will talk in more detail
00:11:40
now we have us, the exile phase
00:11:44
happens 026 029
00:11:48
026 029
00:11:51
we are that is, zero zero eight plus 0
00:11:56
26 if we do this somewhere there will be 0 33
00:12:02
seconds from here we can say 030 to the trend
00:12:07
but up to 0 36 139 it means to sit down then I will survive
00:12:13
points lasting
00:12:15
30 30 30 seconds what is it depend on what
00:12:19
time we will take what to take it will be
00:12:22
like you have a racist you these are telling you
00:12:27
grandson mechanism systole tell me what is
00:12:31
happening there you this whole mechanism is
00:12:34
burning and bellows sister it consists of a
00:12:37
voltage phase and a zina phase
00:12:39
voltage phase social networks asynchrony
00:12:41
abbreviation read synchronously and contraction
00:12:43
digitization occurs asynchronously and
00:12:45
contraction of the ventricular wall from
00:12:47
unequal while the shape changes the
00:12:50
pressure does not increase and so on and so on and so
00:12:53
on this will be a lot of
00:12:55
words now we asked to
00:12:56
sort it out goes about dio became so now
00:13:03
for the sake of deans she has a cold
00:13:06
Greek perry
00:13:07
isometric relaxation and the
00:13:10
filling phase is simply the diastolic period
00:13:13
here for css and also from two periods and
00:13:16
one phase now look also 5 questions
00:13:20
for these that is five questions you know it
00:13:23
will be easier the first simply
00:13:26
diastolic period about the details
00:13:29
means what it looks like this is the
00:13:31
diastolic rod in front of the semilunar valves like
00:13:34
this club we are able to burn them out here the
00:13:38
valves are closed along the lunar open so the
00:13:44
physiological meaning is that here
00:13:47
the blood begins in the opposite direction from the
00:13:52
main vessels of the ventricles but it is
00:13:55
as if the blood is filled in the pockets of the
00:14:00
semilunar valves here the
00:14:03
semilunar valves begin to close but here
00:14:05
it is not closed it begins
00:14:08
if in more detail physiology the meaning
00:14:11
you are talking about is from the moment the
00:14:13
expulsion stops, the expulsion stops until the
00:14:19
semilunar valves close, this period
00:14:22
is called what is cool diastolic
00:14:24
before the
00:14:25
physiology meaning they said the duration the
00:14:27
duration of it is 00 1400 2 seconds where you
00:14:37
can write down you burn only on this day
00:14:43
only us witch edge duration
00:14:47
zero we have already figured out now about
00:14:50
isometric time with you isometric that
00:14:52
it is you who are burning isometric time it and
00:14:54
the state of the valve you are burning means the
00:14:58
institute too the valve can mean the
00:15:00
state of the valve all the valves are closed that
00:15:02
is, both the leaflet and semilunar valves are
00:15:05
closed here the pressure decreases to 0
00:15:09
millimeters of mercury to 0
00:15:12
millimeters of mercury why because
00:15:15
that here the blood is gradually filling up
00:15:18
in the sight
00:15:19
here the blood is already becoming larger and as a
00:15:23
result here in the atria there is
00:15:26
already a lot of blood and the pressure of which
00:15:28
increases for the blood to move from the
00:15:31
atria to the vein what
00:15:34
pressure is needed 0 so again what are you
00:15:37
saying isometric relaxation
00:15:39
state valves burn out leaflet
00:15:42
semilunar valves are closed
00:15:44
physiological significance the pressure in the
00:15:46
ventricles of both the right and left decreases to
00:15:49
0
00:15:50
millimeters of mercury here is the
00:15:52
duration duration this is zero zero
00:15:55
eight seconds now prophase filling so
00:15:59
that the filling phase knows I’ll delete these
00:16:02
two to make it easier to understand we Harry the
00:16:07
filling phase look here phases in
00:16:11
direction but there are two types:
00:16:13
passive and active proxy passive
00:16:21
and active state look what is happening
00:16:24
here and there is a lot of blood
00:16:31
when there is a lot of blood here the pressure in the left
00:16:37
atrium increases to 5 8
00:16:39
millimeters of mercury the pressure in the
00:16:41
left atrium is up to 23 that is, plus 7
00:16:46
types plus 58 and our labor plus 2 3 millimeters of
00:16:49
mercury and as a result of which the
00:16:53
first expulsion occurs due to
00:16:56
pressure, that is, here the atrium does not
00:16:59
contract because under the influence of pressure
00:17:02
it was called what passive filling is,
00:17:05
filling is what I live for.
00:17:07
and when the blood in the atrium decreases and
00:17:12
in the ventricles of which the
00:17:16
filling rate increases as a result of which the filling rate
00:17:19
decreases when the filling rate
00:17:21
fits in,
00:17:24
atrial systole comes to help when the atrium
00:17:27
contracts the rest of the blood conducts
00:17:31
where into the ventricle
00:17:32
therefore when the contraction occurs,
00:17:35
energy is needed for contraction
00:17:37
and when energy is needed it will be something
00:17:39
active why
00:17:41
transport therefore and Harry the first question is
00:17:45
what is it burn out phase filling phase
00:17:48
filling state of the valves you are burning
00:17:51
flaps open semilunar closed
00:17:53
that's what happens background physiological
00:17:58
meaning filling happens what veins good luck
00:18:00
filling stomach go from 2
00:18:02
types these are passive and active-passive
00:18:05
this is due to high pressure in the
00:18:08
atrium in the left atrium plus 5 8
00:18:11
millimeters but weakly
00:18:12
to the left and right squat this plus 2 3
00:18:16
millimeters of mercury and the second is
00:18:18
active transport active trans but the
00:18:20
queues are also divided into active
00:18:23
transport occurs when the system of which is the
00:18:27
stomach 6 sight since the
00:18:30
filling rate of which the
00:18:33
duration decreases so that the duration responds the
00:18:38
duration responds passively in
00:18:41
turn and is divided into fast and slow
00:18:46
two mechanisms, then the same first
00:18:49
pressure more on the backs decreases
00:18:51
slowly
00:18:52
it then arises and so this is to
00:18:54
determine the long duration of
00:18:57
passive fast filling
00:18:59
under very slow filling and active
00:19:03
filling this will be zero zero
00:19:05
eight seconds this will be 0 17 seconds and
00:19:09
this is 0 10 seconds or you can light up 01
00:19:14
if we combine 020 80 seconds 028
00:19:19
what seconds arises what
00:19:22
during the filling phases so the duration we have
00:19:26
determined and recording recording there are two
00:19:30
types of dependence this is passive or
00:19:32
actyon if it’s passive you say only
00:19:36
in FIG game
00:19:37
and if it’s active you say fay g&g
00:19:45
when there’s only one thing you look like in a tailcoat when
00:19:48
here from 2 you call active and the
00:19:51
filling is recorded when
00:19:54
recording synchronously in hockey and
00:19:56
pegs and taiga at the beginning you won’t
00:19:59
only stand in front because it starts from
00:20:02
fa ke the day ends with what
00:20:04
in the end this is how you go what syst
00:20:09
cardiac cycle that is,
00:20:12
you will answer 5 questions easier for you and to train on yourself
00:20:16
to remember this you
00:20:20
take you take 6 circles like this you
00:20:25
draw 1 2 3 4
00:20:29

6 now look right away to start this
00:20:42
wasps let's draw this is called synchronicity
00:20:45
or rather the state of the valve burn out the
00:20:49
flap valves of which are open on the
00:20:52
lunar ones which are
00:20:53
closed here what is happening is
00:20:56
asynchronous contraction of the old ones live
00:21:00
its duration is 0 04 00
00:21:03
5 seconds and it is determined then on the egege
00:21:07
torch 2 isometric contraction
00:21:10
this figure reflects the
00:21:12
isometric contraction of the leaflet and
00:21:16
semilunar valves which are closed here the
00:21:19
pressure in the left ventricle increases
00:21:21
to 780 millimeters here in the right ventricle
00:21:26
alive up to 10-15 but why expulsion does not
00:21:30
occur because the pressure in the
00:21:32
great vessels is greater
00:21:34
therefore then there are 10 15 his strength is not
00:21:38
enough to overcome 20 for it to
00:21:42
happen in exile it is necessary 25 33 this
00:21:46
phase and where can you write down you are burning VCG
00:21:53
and tags it’s just in the diagram field
00:21:56
cardiogram
00:21:57
eco gates eggs agent easier to remember
00:22:00
through this remember well, we haven’t
00:22:03
gone through it yet fakeagent Magra me a recording of the
00:22:06
arterial pulse from the situation
00:22:07
heart you have not yet led to the
00:22:10
fifth question you are stupid and take a tooth and
00:22:12
cram and yes, that is, remember and the
00:22:14
third is the filling phase the expulsion phase expulsion of
00:22:22
the eyes and knowledge you burn fast and
00:22:24
slow and then the leaf valve
00:22:27
why the semilunar valves are closed
00:22:29
quickly and knowledge of the pressure increases the
00:22:31
pressure continues to increase
00:22:33
alive up to 130 140 millimeters of mercury
00:22:37
to the right live up to 7 to 25 30 as a
00:22:41
result of which rapid
00:22:43
expulsion occurs and in a slow change it will pass until the
00:22:45
pressure in the main ventricle is equal the
00:22:48
same goes what in diastole
00:22:52
successive children and its peculiarity
00:22:54
is that this is how it goes like a figure eight
00:22:58
when it fills, fill and then
00:23:04
start back why there is
00:23:06
no filling happening here and it is already filled
00:23:09
when it begins after which the
00:23:11
filling phases are the essence of this drawing so that we
00:23:14
will explain this to you, that is after the
00:23:17
filling phase, asynchronous
00:23:20
contraction begins and preparing means both of
00:23:23
them prepare the ventricle
00:23:25
for the ejection phase, and during dias you are
00:23:29
preparing the filling so that the
00:23:31
vol 6 ventricle will arise again,
00:23:36
this topic was about the cardiac cycle,
00:23:38
if you study this topic in more detail
00:23:41
and it will be easier for you about
00:23:43
auscultation auscultation iPhone
00:23:47
cardiograms auscultation Ivan that is,
00:23:49
murmurs pontoons as a mechanism of occurrence
00:23:52
producing everything so Michal goes if
00:23:56
someone asks you a question, well, what are the mechanics of
00:23:58
systole and diastole Harry, you can do all this
00:24:01
or another question, well, about the cardiac cycle,
00:24:03
tell me, God forbid, it grew up is burning
00:24:06
remember this so that the photo of the genius
00:24:10
cult is something you can remember more easily,
00:24:14
so thank you for your attention, support
00:24:18
