Nonsustained ventricular tachycardia was the initial and only clinical manifestation of myocardial ischemia in a 64-year-old woman evaluated for new onset palpitations. There was no ECG or echocardiographic evidence of ischemia but emergent coronary angiography revealed critical lesions. After angioplasty and stenting of the right coronary artery, ventricular ectopy disappeared. This report documents a mechanism of initiation of sustained ventricular arrhythmias.
一名64岁女性因新发心悸接受评估，非持续性室性心动过速是心肌缺血的初始且唯一临床表现。心电图和超声心动图均无缺血证据，但急诊冠状动脉造影显示存在严重病变。右冠状动脉进行血管成形术和支架置入术后，室性早搏消失。本报告记录了持续性室性心律失常的一种起始机制。
