Death will occur unless a perfusing rhythm is restored within seconds to minutes; 0.1% to 0.2% of the population has CA due to rapid ventricular VT or VF each year. The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, following a period of robust contraction and pumping of blood, called systole. After emptying, the heart relaxes and expands to receive another influx of blood returning from the lungs and other systems of the body, before again contracting to pump blood … hastings tracking

WebBrent Monk. 12 years ago. Troponin itself does not regulate speed or force of contraction. Speed of contraction is determined by the type of muscle fiber. i.e. fast twitch fibers have faster ATPase activity and faster tension development as a result.
