Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
Interruptions of coronary circulation quickly cause heart attacks (myocardial infarctions), in which the heart muscle is damaged by oxygen starvation. Such interruptions are usually caused by coronary ischemia linked to coronary artery disease, and sometimes to embolism from other causes like obstruction in blood flow through vessels.
Weakened Venous valves: these are crucial towards ensuring upward flow to the heart from the lower extremities. If weakened, they may fail to close properly which leads to backwards blood flow/blood pooling. This can lead to slower blood flow in the veins. [8] Ultrasonography-Doppler ultrasound

In cardiology, a cardiac shunt is a pattern of blood flow in the heart that deviates from the normal circuit of the circulatory system.It may be described as right-left, left-right or bidirectional, or as systemic-to-pulmonary or pulmonary-to-systemic.

For this reason, the blood flow velocity is the fastest in the middle of the vessel and slowest at the vessel wall. In most cases, the mean velocity is used. [18] There are many ways to measure blood flow velocity, like videocapillary microscoping with frame-to-frame analysis, or laser Doppler anemometry. [19]
