Cardiovascular Physiology

What is the Anrep effect?

The Anrep effect is an intrinsic myocardial reflex whereby an increase in afterload causes an increase in contractility

What is the Frank-Starling?

The Frank-Starling law is an intrinsic myocardial reflex wherby an increased end-diastolic volume (preload) causes an increase in contractility

What is afterload?

Afterload is the pressure the left ventricle must generate to open the aortic valve and eject blood in systole
