EKG CH 1

Name the phases of diastole

rapid filling → diastasis → atrial kick
What happens that allows the filling in diastole?

AV valve pops open because of pressure gradient
What is diastasis?

flow in ventricles slows as pressure equalizes
Describe the atrial kick

atria contracts=squeezes remainder blood into ventricles
What perfuses during diastole

coronary arteries
What are the phases of systole

isovol contraction → ventricular ejection → prodiastole → isovol relaxation
What is isovolumertric contraction

ventricles contract but there is NO blood flow
What is ventricular ejection

valves open=blood pours OUT of ventricles
What is protodiastole

flow slows as pressure equalizes
What is isovolumetric relaxation

ventricles relax=valves close
