   -       A.       B.       C.       D.       E.       F.	QRS Complex

   A.	Time between ventricular diastole and systole
   B.	Ventricular repolarization
   C.	Atrial Depolarization
   D.	Time between ventricular systole and diastole
   E.	Time between atrial and ventricular systole
   F.	Duration of ventricular systole

Answer 1

The left and right AV bundles of the cardiac conduction system are located in the

D.Interventricular septum

Explanation:There are two branches of the bundle of his : the left bundle branch and right bundle branch which are located along the interventricular septum

Question:3

T wave - B.Ventricular repolarisation (0.27 sec), A, D ,E

S-T interval - B.Ventricular repolarisation (0.32 sec), A, D ,E

T-P interval - B.Ventricular repolarisation C.atrial depolarisation (0.2 sec),F

QRS complex - F(ventricular depolarisation and atrial repolarisation merges with QRS complex)
