Cardiac cycle — Flashcards

Which stage of sleep do penile and clitoral tumescence occur? _____

The v wave on jugular venous pulse corresponds to _____

The a wave on jugular venous pulse corresponds to _____

The abnormal heart sound _____ may be audible during rapid ventricular filling (early diastole)

Activation of M2 receptors in the SA node produces a decrease in _____ channel activity, which decreases the rate of phase 4 depolarization and thus heart rate

Coronary blood flow peaks in early _____ (systole/diastole)

In _____ splitting, the P2 sound occurs before a delayed A2 sound

_____ are low-resistance paths between cardiac cells that allow for rapid electrical spread of action potentials

How does the rate of upstroke in a SA node action potential compare to that of a myocardial action potential?_____

The abnormal heart sound _____ may be audible during atrial systole (late ventricular diastole)
