WebThis corresponds to the middle of T wave on the ECG waveform and the dicrotic notch of the arterial pressure trace. As aortic valve closure has occurred balloon inflation causes a sharp upstroke on the arterial pressure waveform followed by a tall peak which represents the assisted diastolic pressure. Deflation occurs at the onset of systole ... WebThe closure of the aortic valve causes a rapid change in pressure in the aorta called the incisura. This short sharp change in pressure is rapidly attenuated down the arterial tree. The pulse wave form is also reflected from branches in the arterial tree and gives rise to a dicrotic notch in main arteries. WebThe dicrotic notch which is a drop on the down slope shows systole termination and depicts the aortic valve closure and successive backward flow. The position of the dicrotic notch throughout the cardiac activity differs as per the duration of aortic closure. Dicrotic notch plays an essential part in sclerosis, occlusion, crystal red bird
