Among 160 patients with mitral-valve prolapse but no other illness there were 118 with cardiac arrhythmias. 30 had frequent or multifocal ventricular premature systoles, 21 had coupled ventricular extrasystoles, and seven had ventricular tachycardia. In six patients the prematurity index was under 1. Supraventricular premature systoles were registered in 56 patients, with seven each having paroxysmal atrial tachycardia and paroxysmal atrial flutter or fibrillation. Ventricular arrhythmias were significantly more frequent in late-systolic prolapse and with positive auscultation findings (systolic click or systolic murmur). Long-term ECG monitoring was more valuable than an exercise ECG. About half the patients with frequent arrhythmias had palpitations and rapid heart action. Coupled ventricular premature systoles and ventricular tachycardias, as well as R-on-T were relatively rare; our findings thus tend to suggest a relatively favourable prognosis for these arrhythmias.
在160例仅有二尖瓣脱垂而无其他疾病的患者中，有118例出现心律失常。30例有频发或多灶性室性早搏，21例有室性成对早搏，7例有室性心动过速。6例患者的过早搏动指数低于1。56例患者记录到室上性早搏，其中7例分别有阵发性房性心动过速和阵发性心房扑动或颤动。晚期收缩期脱垂和听诊有阳性发现（收缩期喀喇音或收缩期杂音）的患者室性心律失常明显更常见。长期心电图监测比运动心电图更有价值。约一半有频发心律失常的患者有心悸和心动过速。室性成对早搏、室性心动过速以及R波落在T波上相对少见；因此我们的研究结果倾向于提示这些心律失常的预后相对良好。
