1

Bulbus cordis

Smooth parts of left and right ventricles

2

Primative pulmonary vein

smooth part of left atrium

3

Right horn of sinus venosus

Smooth part of right atrium

4

Left horn of sinus venosus

Coronary sinus

5

Valve development

A/P: endocardial cushions of outflow tract M/T: fused endocardial cushions of AV canal

6

Allantois --> urachus -->

Median umbilical ligament

7

Ubilical arteries -->

Medial umbilical ligaments

8

Umbilical vein

LIgamentum teres hepatis (contained in falciform ligament)

9

Aortic stenosis radiation

to corotids

10

Pulsus parvus et tardus

Aortic stenosis

11

Mitral regurg radiation

Axilla

12

Tricuspid regurg radiation

right sternal border

13

Hyperdynamic pulse / bounding

Aortic regurg

14

Quinkes

Aortic regurg

15

Opening snap

Mitral stenosis

16

continuous machine gun murmor

PDA

17

Left infraclavicular area

PDA

18

J Joint

Junction between end of QRS and beginning of ST segment

19

Speed of conduction: (atria, AV, purkinje, Ventricles)

Purkinje > Atria > Ventricles > AV node

20

Speed of Pace makers: SA, AV, Bundle of His/purkinje/ventricles

SA>AV>Bundle of His/purkinje/ventricles

21

Conduction pathway after AV node:

Common bundles --> Bundle branches --> fascicles --> purkinje fibers --> ventricles

22

Blood supply to AV node

RCA, located in the posteroinferior part of interatrial septum

23

Romano-Ward syndrome

AD, Congenital long QT syndrome (pure cardio phenotype)

24

Jervell and Lange-Nielsen syndrome

AR, Congenital Long QT syndrome (Sensorineural deafness)

25

Brugada syndrome

AD, Asian males, ECG pattern of pseudo-right bundle branch block and ST elevations in V1-V3. Increased risk of V-tach, and SCD Treat: implantable defibrillator

26

Wolff-parkinson-white syndrome

MCC of ventricular pre-excitation syndrome. Atria -->Bundle of kent --> ventricles --> characteristic delta wave with widened QRS complex and shortened PR interval Complications: Re-entry circuit --> supraventricular tachycardia

27

Cushing reaction:

Triad of Systolic HTN, Bradycardia, Respiratory irregularity Phase 1: Increased ICP --> constricted arterioles --> cerebral ischemia --> increased pCO2 / H+ --> reflex increased sympathetics --> Increased cardiac output / vasoconstriction Phase 2: Increased CO --> aortic arch --> reflex PSNS --> brady cardia (Also; Mechanical pressure on vagus --> PSNS)

28

Prostacyclin: Platelet aggregation, vaso___, vascular permeabilty, Leukocytes

increased Platelet aggregation, vasodilation, increased vascular permeabilty, Leukocytes chemotaxis

29

Prostacyclin physiological antagonist

TXA2

30

Alcohol exposure (anomalies):

VSD, ASD, PDA, Tetralogy of Fallot
