During systole, is there relatively constant blood flow to the right ventricular myocardium?_____

_____ is the first phase of a cardiac cycle and represents the period between mitral valve closing and aortic valve opening

Phase 0 of the myocardial action potential is caused by opening of voltage-gated _____ channels

Cardiac O2 consumption is directly related to the amount of _____ developed by the ventricles

What is the approximate normal pressure in the right ventricle (systolic and diastolic)? _____

Entry of Ca2+ into the myocardial cell during the myocardial action potential triggers further release of Ca2+ through _____ receptors (Ca2+ release channels)

Conduction velocity through the AV node is _____ than in the other cardiac tissues

Patients with severe aortic stenosis depend upon _____ for maintenance of preload

Is the fourth heart sound (S4) normally audible in adults?_____
