Review Articles

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.
