A reduced EA ratio during
A reduced EA ratio during this period is diagnostic for damage, and mitral stenosis is a common cause of murmurs during this phase. Seven-eighths of the time, the atria are in this phase, while the closing of the semilunar valves begins this phase in the ventricles. This is the phase of the cardiac cycle when the heart chambers relax and fill with blood. Associated with the lower reading of a person's blood pressure, identify this phase usually contrasted with systole (SISS-toh-lee).
