What initiates the p wave?
cardiac cycle
Which phase in cardiac cycle is systolic pressure?
Blood flows into the relaxed atria while the ventricles contract. <rephrased> The ventricles contract, carrying blood into the aorta, and blood flows into the relaxed atria.
During what phase of cardiac cycle are all four chambers in diastole?
Once the ventricles contraction phase is over, the diastole starts. Then all the four chambers are in diastole, till the atria start to contract.
What is the graphic of heart sounds produced during the cardiac cycle?
Phonocardiogram
What is the phase of the cardiac cycle that is caused by the sliding of actin and myosin?
Systole
Which is the phase of cardiac cycle in which the auricles contract?
