Major ventricular arrhythmias occurring concurrently with myocardial ischemia are presumed to be the most frequent mechanism for sudden cardiac death. Two hundred eighteen catheterized patients with angina pectoris at rest were reviewed to identify clinical, ECG, and arteriographic features that might correlate with the presence of serious ventricular arrhythmias occurring during episodes of rest pain. Ventricular arrhythmias during episodes of rest pain were significantly more common in patients who manifested transient ST segment elevation in the anterior leads and in patients with marked transient ST segment shifts (greater than 5 mm). Ventricular arrhythmias during episodes of rest pain were not more common in patients with extensive coronary artery disease.
与心肌缺血同时发生的严重室性心律失常被认为是心源性猝死最常见的机制。对218例静息性心绞痛患者进行了导管检查，以确定可能与静息痛发作期间严重室性心律失常的存在相关的临床、心电图和血管造影特征。静息痛发作期间的室性心律失常在胸前导联出现短暂ST段抬高的患者以及ST段有明显短暂偏移（大于5毫米）的患者中明显更为常见。静息痛发作期间的室性心律失常在冠状动脉疾病广泛的患者中并不更常见。
