Q

Great Controlling System of the Heart

Study These Flashcards
A

A. Autonomic Nervous System
1. Sympathetic
2. Para Sympathetic
B. Conducting Zone
1. SA Node (Sinoatrial/ Sinus Node)
2. AV (Atrioventricular) Node
3. Bundle of His
4. Purkinje Fiber

22
Q

Located in the Right Atrium and initiates depolarization

Study These Flashcards
A

SA (Sinoatrial) Node or Sinus Node

23
Q

Located behind the tricuspid valve. Site for heart block.

Study These Flashcards
A

AV (Atrioventricular) Node

24
Q

Located in the IV septum. Conducts from the atrium to the ventricles and primary pacemaker of the heart.

Study These Flashcards
A

Bundle of His

25
15/40x per minute. Surround 2 ventricles. Largest pacemaker of the heart. Conducts AP beginning at the apex upward to the ventricular myocardium
Purkinje Fiber
26
Divides the chamber of the heart
Septum
27
Septums of the Heart
- Atrioventricular Septum (ventricles and atria) - Interatrical Septum (Atria) - Interventricular Septum (Ventricles)
28
Pumping action of the heart
Diastole and Systole
29
Ventricular Relaxation. Ventricles must stretch to accommodate the ventricular filling
Diastole
30
Ventricular Contraction. Ventricles must be able to contract to eject the stroke volume.
Systole
31
When increase quantities of blood flow into the heart, the increased blood stretches the walls of the heart chambers.
Frank- Starling Law
32
Cardiac Cycle
A. Diastole - Period of Rapid Filling B. Systole - Period of Isovolmic Contraction - Period of Ejection - Period of Isovolmic Relaxation
33
Period where the blood flows passively from atria to ventricles
Period of Rapid Filling of Ventricle (Diastole)
34
Blood flow in Diastole
First 1/3 (75%) of blood flow from atrium to ventricles Middle 3rd- Continuous blood flow Last 1/3 (25) flow from atrium to ventricles by atrial kick (contracts minimally to get the last blood
35
Valves in Diastole
Atrioventricular Valve is Open while Sinular Valve is Close (Ventricles are relaxed and do not contract. FLOW only)
36
Period where the blood is already in the ventricles. There is also an increase in ventricular pressure in order to close the AV valve. Contraction will happen but there is no emptying yet. AV AND SL VALVES ARE CLOSED
Period of Isovolmic Contraction (Systole)
37
Period of Ejection
Afterload - Ventricular force to open the SL Valves RV- 8 mmHg (Pulmonary Artery) LV- 80 mmHg (Aorta)
38
Blood flow in Period Of Ejection (Systole)
First 1/3 of Ejection - 70% of blood is ejected to pulmonary artery and aorta Last 2/3 of Ejection - 30% blood is ejected yo pulmonary artery and aorta AV valves are closed and SL Valves Open
39
Period where the blood is in the blood vessels. There is a decrease in ventricular pressure to close the SL valves. SL AND AV Valves are closed but will eventually open to start new filling.
Period of Isovolmic Relaxation (Systole)
40
Heart sound that is - Longer - Louder - Lower in pitch - Caused by the closure of AV valves - Beginning of the ventricular Systole
S1 (LUB)
41
Heart sound that is - Shorter - Not loud as S1 - Caused by the closure of SL Valves - Beginning of Ventricular Diastole
S2 (DuB
42
Abnormal heart sound that is cause by the rapid filling of Ventricles. CBF. Ventricular Gallop. Rapid filling in Systole
S3
43
Heart sound that is atrial systole and causes Heart Attach and Hypertension. Atrial Gallop
S4
44
Systolic and Diastolic Pressure
Systolic (Highest Arterial Pressure)120mmHG Diastolic (Lowest Arterial Pressure) 80 mmHG Normal BP 120/80
45
Heart Rate and Pulse Rate
Heart Rate (N= 60-100 Beats per Minute) Pulse Rate SBp- DBP Average pressure of peripheral pulse N= 40 mmhg
46
Amount of blood left
Diastolic - 120 ml Systolic - 50 ml
47
Amount of blood pumped by the ventricles per contraction
Stroke Volume
48
Stroke Volume = to
N= 70 mL
49
Amount of blood pumped by the ventricles per minute
Cardiac Output
50
Normal Cardiac Output
4-6 Liters of Blood Cardiac Output= Stroke Volume x hour
