Dicrotic Notch: Significance In Aortic Valve Disorders And Blood Pressure Assessment
The dicrotic notch is an indentation in the arterial pulse wave caused by the closure of the aortic valve during ventricular diastole. It appears as a distinct dip in the pulse tracing, indicating the end of ventricular systole and the onset of diastole. The notch’s shape can vary depending on individual factors, reflecting the stiffness…
