作者观察了75例心肌梗塞病人。在磁带式心电图记录监测下,于发病第十五天后,心律失常及传导障碍的发生率为85％,最常见的是室性早搏(72.5％)窦性心动过缓(40％)及房性早搏(37.5％)。(见表)室性早搏最常见(29例)并且其中9例系多发性、成对、节律异常的(多源)或早期的(即R重T)。第二位是窦性心动过缓,较窦性心动过速常见。与发病的第1天不同,那时的窦性心动过速最常见。第三位是房性早搏。也发现了阵发性室上性心动过速及室性心动过速,房颤、房扑、房室传导阻滞Ⅲ The authors observed 75 patients with myocardial infarction. The incidence of arrhythmia and conduction disturbances was 85% after tape-based electrocardiographic recording monitoring on the fifteenth day of onset, the most common being premature ventricular contractions (72.5%) sinus bradycardia (40%) and atrial Premature beats (37.5%). (See Table) Ventricular premature beats are most common (29 patients) and nine of these are multiple, paired, abnormally rhythmic (multi-source) or early (ie, R T). The second is sinus bradycardia, more common than sinus tachycardia. Unlike the first day of onset, sinus tachycardia was most common at that time. The third is atrial premature beats. Also found in paroxysmal supraventricular tachycardia and ventricular tachycardia, atrial fibrillation, atrial flutter, atrioventricular block Ⅲ
