A patient with hypertrophic cardiomyopathy, syncope, and frequent ventricular tachycardia was monitored during a syncopal episode. An unrecordable blood pressure and the loss of a left ventricular outflow tract murmur without evidence of arrhythmia suggested a primary haemodynamic mechanism such as reduction in left ventricular volume.
一名患有肥厚型心肌病、晕厥和频发室性心动过速的患者在一次晕厥发作期间接受了监测。血压无法记录，且左心室流出道杂音消失，同时没有心律失常的证据，提示存在原发性血流动力学机制，如左心室容积减少。
