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.
分析动脉压力波形在现代实践中仍然有用，可以评估可能表明心血管参数显著异常的变化。认识切迹和降支波的异常应提醒临床医生寻找特定的病因因素。了解切迹和降支切迹的生理起源可以增强其在准确诊断异常血液动力学状态中的临床应用。本文综述了引起和影响动脉波形中切迹形成的血液动力学事件。
