The blow to the chest at precisely the wrong time in the cardiac cycle causes an electrical abnormality in the heart, resulting in an irregular heart rhythm that cannot pump blood to the body.

Contracting causes a temporary spike in blood volume and increased pressure on the artery walls, and it is often referred to ...

Murmurs are described by their timing in the cardiac cycle, intensity, shape, pitch, location, radiation and response to dynamic maneuvers. Using the aforementioned criteria, a clinician can ...

Heart sounds can be described by their intensity, pitch, location, quality and timing in the cardiac cycle. Intensity: Heart sounds can be described as increased in intensity (loud), decreased in ...

The volume of blood pumped through each ventricle per minute can be calculated as cardiac output. Cardiac output can be calculated using the following equation: Stroke volume close stroke ...
