Cardiac cycle — Flashcards

Which phase in the SA node accounts for its pacemaker activity and automaticity?_____

How do aortic and ventricular pressure change during reduced ventricular ejection?_____

Slowed conduction through the AV node normally causes a _____-msec delay, allowing time for ventricular filling

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

The heart sound _____ may be audible during isovolumetric contraction

The calcium channels that open during the plateau phase (myocardial action potential) are _____-type channels

What type of action potential occurs in the ventricles, atria, and Purkinje system?_____

How does aortic pressure change during rapid ventricular ejection?_____

The y descent on jugular venous pulse corresponds to _____

Conduction velocity is increased when the space (length) constant is _____
