“Incisura” of the aerial pulse corresponds to:
Correct Answer: Closure of the aoic valve
Description: Incisura is the notch seen in the aerial pulse tracing due to closure of the aoic valve. More peripheral aerial pulsations exhibit an analogous notch called "dicrotic notch". At the end of ventricular systole, there is sudden change in the direction of blood ('protodiastole'), followed by closure of the aoic valve. These events are responsible for the notch, a sudden alteration in the aerial tracing. It is followed by a slowly declining pressure wave, indicating the ventricular diastole.
