1

Truncus arteriosus (TA)

Ascending aorta and pulmonary trunk

2

Bulbus cordis

Smooth parts (outflow tract) of left and right ventricles

3

Primitive atria

Trabeculated part of left and right atria

4

Primitive ventricle

Trabeculated part of left and right ventricles

5

Primitive pulmonary vein

Smooth part of left atrium

6

Left horn of sinus venosus (SV)

Coronary sinus

7

Right horn of SV

Smooth part of right atrium

8

Right common cardinal vein and right anterior cardinal vein

SVC

9

Aortic area murmurs

Systolic murmur =>
Aortic stenosis
Flow murmur
Aortic valve sclerosis

10

Left sternal border murmurs:

Diastolic murmur=>
Aortic regurgitation
Pulmonic regurgitation

Systolic murmur =>
Hypertrophic cardiomyopathy

11

Pulmonic area murmurs

Systolic ejection murmur =>
Pulmonic stenosis
Flow murmur (e.g., physiologic murmur)

12

Tricuspid area murmurs

Pansystolic murmur=>
Tricuspid regurgitation
Ventricular septal defect

Diastolic murmur =>
Tricuspid stenosis
Atrial septal defect

13

Mitral area murmurs

Systolic murmur =>
Mitral regurgitation

Diastolic murmur =>
Mitral stenosis

14

BEDSIDE MANEUVER Inspiration

increase intensity of right heart sounds

15

BEDSIDE MANEUVER Hand grip (increase systemic vascular resistance)

Increase intensity of MR, AR, VSD murmurs
decrease intensity of AS, hypertrophic cardiomyopathy murmurs

MVP: increase murmur intensity, later onset of click/murmur

16

BEDSIDE MANEUVER Valsalva (phase II), standing (decrease venous return)

decrease intensity of most murmurs (including AS)
increase intensity of hypertrophic cardiomyopathy murmur

MVP: decrease murmur intensity, earlier onset of click/murmur

17

BEDSIDE MANEUVER Rapid squatting (Increase venous return,increase preload, increase afterload with prolonged squatting)

decrease intensity of hypertrophic cardiomyopathy murmur
increase intensity of AS murmur

MVP: increase murmur intensity, later onset of click/murmur

18

Name the systolic heart sounds

aortic/pulmonic stenosis,
mitral/tricuspid regurgitation,
ventricular septal defect.

19

Name the diastolic heart sounds

aortic/pulmonic regurgitation,
mitral/tricuspid stenosis.

20

ECG P wave

atrial depolarization

Atrial repolarization is masked by QRS complex

21

ECG PR interval

conduction delay through AV node (normally < 200 msec).

22

ECG QRS complex

ventricular depolarization (normally < 120 msec).

23

ECG QT interval

mechanical contraction of the ventricles.

24

ECG T wave

ventricular repolarization.

T-wave inversion may indicate recent MI.

25

ECG ST segment

isoelectric, ventricles depolarized.

26

ECG U wave

caused by hypokalemia, bradycardia

27

Give the speed of conduction in heart

Purkinje > atria > ventricles > AV node.

28

Give pacemakers of heart

SA > AV > bundle of His/ Purkinje/ventricles.

29

What Rx prolong the QT interval?

Sotalol
Risperidone (antipsychotics)
Macrolides
Chloroquine
Protease inhibitors (-navir)
Quinidine (class Ia; also class III)
Thiazides

30

RV MI => name area, coronary artery & ECG leads

inferior wall (RV);
RCA
II, III, aVF
