Explain atrial systole
WebThe electrical stimulus travels down through the conduction pathways and causes the heart's ventricles to contract and pump out blood. The 2 upper chambers of the heart (atria) are stimulated first and contract for a short period of time before the 2 lower chambers of the heart (ventricles). The electrical impulse travels from the sinus node to ... WebAtrial systole lasts approximately 100 ms and ends prior to ventricular systole, as the atrial muscle returns to diastole.

WebMeasuring Atrial Systole. Atrial systole is the contraction of cardiac muscle cells of both left and right atria after electrical stimulation and conduction across the chambers. It starts at the beginning of a heartbeat and ends when another heartbeat begins. The systole causes the pumping of blood in the aorta and pulmonary trunk. WebSep 26, 2024 · Atrial systole: It is the contraction of heart muscle (myocardium) of left and right atria. Generally, both atria contract at the same time. As the atria contract, the blood pressure in each atrium increase forcing additional blood into the ventricles. The additional flow of blood is also known as atrial kick. Atrial diastole:
