Heart systole and diastole video
WebVideos /. Cardiac Cycle. Cardiac Cycle. During one cardiac cycle, all four heart chambers go through a contraction period, called systole, and a relaxation period, called diastole. As a result of the cyclic contraction and relaxation of the ventricles, blood pressure in the pulmonary and systemic circuits rises and falls. Websystole, period of contraction of the ventricles of the heart that occurs between the first and second heart sounds of the cardiac cycle (the sequence of events in a single heart beat). Systole causes the ejection …

WebCardiac Auscultation. Auscultation of the heart requires excellent hearing and the ability to distinguish subtle differences in pitch and timing. Hearing-impaired health care practitioners can use amplified stethoscopes. High-pitched sounds are best heard with the diaphragm of the stethoscope. Low-pitched sounds are best heard with the bell. Websystole, period of contraction of the ventricles of the heart that occurs between the first and moment heart sounds are the cardiac cycle (the set of events in a single heart beat). Systole drives to ejection of blood into the aorta and pulmonary trunk. Lasting usually 0.3 to 0.4 second, ventricular systole is introduced by a extremely brief period of contraction, …
