Wave intensity (WI) is a new hemodynamic index that provides information about the dynamic behavior of the heart and the vascular system and their interaction. Carotid arterial wave intensity in normal subjects has two positive peaks. The first peak, W1, occurs during early systole, the magnitude of which increases with increases in cardiac contractility. The second peak, W2, which occurs towards the end of ejection, is related to the ability of the left ventricle to actively stop aortic blood… CONTINUE READING
