WebCardiac power output (CPO) was first described in 1986 but did not achieve prominence until its identification in 2004 as a strong hemodynamic correlate of mortality in acute myocardial infarction (AMI) complicated by cardiogenic shock. 1 Its use has since gained steam in cardiogenic shock algorithms, regardless of baseline ventricular function–that is, … WebSprinting, burpees, and jump squats will be the HIIT activities. The participants' heart rates will be tracked the entire time. The individuals will repeat the original fitness test eight weeks later to see if there was any improvement in their cardiac output. A heart rate monitor, treadmill, and timer were employed in this investigation.

WebAs mentioned earlier, as energy demands rise (oxygen demands), cardiac output increases. A heart rate of 100/minute will almost always result in more blood ejected per minute than a heart rate of 80/minute. Take for … WebCardiac output is the volume of blood flow from the heart through the ventricles, and is usually measured in litres per minute (L/min).
