BMS10-1024 - Regulation of cardiac function 1

FlashCards por Evian Chai, criado more than 1 year ago

Describe/ explain mechanical events of the cardiac cycle, including changes in pressures/ volumes of the atria and left/ right ventricles, + how these correlate with heart sounds/ECG. Explain origins of heart sounds / murmurs, indicating what is heard normally and abnormalities influence of cardiac filling on force production and its mechanisms. importance of Starling’s law of the heart. ventricular function curve and how SNS impacts it
