39 wiggers diagram cardiac cycle

A Wiggers diagram illustrate events and details of the cardiac cycle with electrographic trace lines, which depict (vertical) changes in a parameter's value as time elapses left-to-right. The ventricular "Diastole", or relaxation, begins with "Isovolumic relaxation", then proceeds through three sub-stages of inflow, namely: "Rapid inflow ... Wiggers diagram records are most commonly used in cardiac care units. The primary benefit of the Wiggers diagram is that it shows several aspects of the cardiac cycle together over time so that doctors can ensure the heart is beating properly. In a healthy heart, electrical impulses from the nervous system control the four chambers.

09/10/2021 · The cardiac cycle is a series of pressure changes that take place within the heart. These pressure changes result in the movement of blood through different chambers of the heart and the body as a whole. These pressure changes originate as conductive electrochemical changes within the myocardium that result in the concentric contraction of cardiac muscle.
