The Cardiac Cycle Phase 1 - Atrial Systole Made EASY!!

The first phase of the Cardiac Cycle is Atrial Systole. In this phase, we see a number of things happening. We take a look at the P wave of the electrocardiogram, the pressure changes in the atria and ventricles, as well as the volume of blood in the ventricles. Get ready to ace this section of your cardiac cycle test.
