What Is The Dicrotic Notch?

The dicrotic notch, a significant and easily recognizable characteristic within the pressure waveform of central arteries, plays a crucial role in understanding the cardiac cycle. Universally acknowledged as a key indicator, this notch distinctly marks the transition from systole, the phase where the heart contracts and ejects blood, to diastole, the relaxation phase where the heart refills with blood. This prominent feature helps healthcare professionals and researchers precisely analyze the timing and efficiency of the heart’s pumping function in central arteries, shedding light on cardiovascular health and performance.

What Causes The Dicrotic Notch Quizlet?

“What leads to the occurrence of a dicrotic notch? The dicrotic notch is a notable feature in the arterial pressure waveform that occurs when, after the initial ejection of blood from the heart into the aorta, there is a brief moment when some blood flows back from the aorta toward the ventricle. This backward flow prompts the closure of the aortic valve, resulting in the characteristic notch in the arterial pressure curve.”
