Left
The pathogenic mechanism responsible for formation of Dextrocardia is
abnormal situs and looping
E wave velocities of the MV and TV change when what is impacted
Myocardium
The pathogenic mechanism responsible for formation of an AVSD is
Extracellular Matrix
After birth all of the flowing veins deliver deoxygenated blood to the heart EXCEPT
Portal veins
SVC
Pulmonary veins
IVC
Pulmonary veins
The 3 main bundles of the cardiac conduction system include all the following
Bachman’s bundle
Thorel’s bundle
Wenkebach’s bundle
Broad pyramidal and triangular all describe
Right atrial appendage
The AO and PA are formed during which stage of embryology
Stage IV
On an EKG the time it takes from ventricular contraction to atrial contraction is the
RP interval
The interatrial and interventricular septa are formed during which stage of embryology
Stage III
Following birth the Ductus arteriosus usually closes completely within
3-4 days
A tortuous Ductus arteriosus is a normal variant seen in the _____ trimester
3rd
After birth the ductus venous becomes the
Ligamentum venosum
Mitral and tricuspid valves are formed during what stage
Stage III
What are the AV valves
Tricuspid and mitral
Semilunar valves
AO valve
PA valve
The coronary sinus receives blood from the
Coronary veins
During diastole blood is prevented from flowing back into the right ventricle by the
Pulmonic valve
The SA and Av nodes are normally located in the
Right atrium
The pathogenic mechanism responsible for formation of a DORV is
Tissue Migration Abnormality
Fetal coronary artery flow is difficult to visualize in the normal fetus prior to what gestational age
31 weeks
The atrioventricular loops forms during which stage of embryology
Stage II
The azygous vein normally drains into
SVC
During diastole which valves are open
Mitral and tricuspid
The inner most layer of the heart wall is the
Endocardium
Blood from the IVC enters the right atrium via the
Eustachian valve
On an EKG atrial contraction occurs the
P wave
Cardiac cycle
P wave -
QRS complex-
T wave -
P - atrial contraction
QRS - ventricular contraction
T wave - ventricular repolarization
