WebJun 8, 2024 · This can be equated to an increased contractility of the heart muscle, resulting in increased cardiac output. Too little pedal power, or impaired contractility, will reduce cardiac output; however, too much effort will result in fatigue, sometimes leading to a complete collapse, with the need to slow down substantially or even to stop. WebJun 30, 2015 · The arterial pulse waveform. The arterial pulse waveform can be separated into three distinct components. The systolic phase, characterised by a rapid increase in pressure to a peak, followed by a rapid decline. This phase begins with the opening of the aortic valve and corresponds to the left ventricular ejection. WebJan 30, 2024 · Decreased contractility also can result from a loss of myocardium as with myocardial infarction, beta-blockers (acutely), non-dihydropyridine Ca++ channel blockers, and dilated cardiomyopathy. Changes in afterload, which is the force of resistance that the ventricle must overcome to empty contents at the beginning of systole, will also shift ... npo patient dry mouth
