17
Q

Aortic valve

A

Right coronary arteries come out of it to supply heart

18
Q

Fibrous skeleton of heart

A

Maintains size and shape, electrical insulator, 4 collagen rings

19
Q

Blood flow

A

Body - SVC/IVC - RA - tricuspid valve - RV - pulmonary valve - lungs - LA - mitral/bicuspid valve - LV - aortic valve - aorta - descending & ascending - body

20
Q

Heart auscultation

A

Aortic - right parasternal, ICS 2
Pulmonic - left parasternal, ICS 2
Tricuspid - left parasternal, ICS 5
Mitral - left midclavicular line, ICS 5

21
Q

Coronary arteries

A

Arise from right and left aortic sinuses, just above aortic valve

22
Q

RCA

A

Right atrium and ventricle, SA node (mostly) and AV node, posterior atrioventricular septum

Branches into post interventricular (determines dominance) and right marginal branch

23
Q

LCA

A

Left atrium and ventricle, AV bundle, some portion of SA node, anterior atrioventricular septum

Branches into ant interventricular (LAD), circumflex (goes to back) and left marginal

24
Q

Venous drainage

A

Great cardiac vein - LAD/ant interventricular (vulnerable during bypass)
Middle cardiac vein - post interventricular
Small cardiac vein - right marginal artery

25
Q

Great cardiac vein

A

LAD/ant interventricular artery
Vulnerable during bypass

26
Q

Middle cardiac vein

A

Post interventricular artery

27
Q

Small cardiac vein

A

Right marginal artery

28
Q

LAD

A

AKA anterior interventricular
Runs with great cardiac vein
Most likely site of occlusion
Supplies AV bundle

29
Q

CAD

A

Caused by coronary atherosclerosis
Accompanied by angina pectoris = chest pain
Treat with coronary artery bypass graft (great saphenous), coronary angioplasty, intravascular stent

30
Q

AV node

A

Right atrium, interaterial septum

31
Q

Bundle of His

A

Interventricular septum

32
Q

Right bundle branch

A

Moderator band, right ventricle wall

33
Q

A

Left ventricle wall

34
Q

Purkinje fibers

A

Interventricular septum, papillary muscles

35
Q

Pacemaker

A

Replaces SA ndoe
L. subclavian - l. brachiocephalic - SVC - right atrium - right ventricle

36
Q

Innervation of heart

A

Parasympathetic = vagus
Sympathetic = T1-T4

37
Q

Cardiac referred pain

A

Transmitted by visceral afferent fibers which travel with sympathetic fibers

38
Q

Veins path

A

Internal jugulars and subclavian go into brachiocephalic and into SVC

39
Q

Arteries path

A

Right common carotid and subclavian go to brachiocephalic trunk
No brachiocephalic trunk on left
Go into aorta

40
Q

A

Left ventricle, drains into coronary sinus

41
Q

Anterior cardiac vein

A

Right ventricle, drains into right atrium

42
Q

Apex of heart

A

Left 5th ICS midclavicular line
