Fisiología cardíaca: factores determinantes del gasto cardíaco rápido, fácil y sencillo en 5 minutos

In this video of cardiac physiology the 4 factors that determine the cardiac output (volume of blood that the heart pumps in one minute) are explained and which are: the heart rate, the contractility (inotropism) of the heart, the preload and afterload. Preload and afterload are applications of the law of tension or Laplace's law to biology. In this central topic of the cardiovascular system, the volumes of the ventricles or cardiac volumes are defined as the residual volume, heartbeat volume, final diastolic volume and ventricle filling volume.
