Analysis of the arterial pressure waveform remains useful in modern practice to assess alterations that may indicate significant abnormalities of cardiovascular parameters. The recognition of abnormalities of the incisura and dicrotic wave should alert the clinician to seek specific etiologic factors. Understanding the physiological origins of the incisura and dicrotic notch enhance its clinical utility in accurately diagnosing abnormal hemodynamic states. This review summarizes the hemodynamic events causing and affecting the inscription of the incisura in the arterial waveform.

Purpose Of Review: The dicrotic notch (DN) has long been considered a marker of arterial stiffness and compliance. Herein, we explored the recent developments in vascular medicine research in an attempt to assess the DN utility in clinical cardiovascular medicine.
Recent Findings: Since its discovery, several studies have attempted to measure the changes in different parameters of the DN in physiological and pathological states.

In previous research, time-delay (Δt) was a more important parameter than the reflection coefficient in the individual transfer function of central aortic pressure reconstruction. The Δt can be obtained by electrocardiography (ECG) or phonocardiography (PCG). Because the pre-ejection period remains an uncertain factor, the present study used ECG and PCG to define the delay time and analyzed the accuracy of the reconstruction results.

Hypertension remains a common public health challenge because of its prevalence and increase in co-morbid cardiovascular diseases. Black males have disproportionate pathophysiological consequences of hypertension compared with any other group in the United States. Alterations in arterial wall compliance and autonomic function often precede the onset of disease.

Objective: It has been recently shown that there is a match between dicrotic notch and mean pulmonary artery (PA) pressures in spontaneously breathing patients studied by means of high-fidelity pressure catheters. The aim of the study was to analyze the relation between mean PA pressure and PA pressure at the incisura by using a Swan-Ganz catheter in critically ill, mechanically ventilated patients.
Measurements And Results: Fluid-filled PA pressures were obtained over four ventilatory cycles in 32 consecutive, mechanically ventilated patients in the intensive care unit.
