Twenty four-hour ambulatory ECG monitoring were examined in 68 patients (33 patients in a young group and 35 patients in an adult group) with mitral valve prolapse (MVP) in order to characterize the features of arrhythmias in young patients with MVP in comparison with those in adult patients. Diagnosis of MVP was made by two-dimensional echocardiography. On 24-hour ambulatory ECG monitoring 29 patients (88%) in a young group had arrhythmias which was as frequent as those in adult group, but serious ventricular arrhythmias were more often detected in the young group (7 patients) than in the adult group (2 patients). It was considered that arrhythmias in young patients with MVP were frequently serious but accompanied without any symptoms and cardiac dysfunction.
对68例二尖瓣脱垂（MVP）患者（33例为青年组，35例为成年组）进行了24小时动态心电图监测，以比较青年MVP患者与成年患者心律失常的特征。MVP的诊断通过二维超声心动图进行。在24小时动态心电图监测中，青年组29例患者（88%）出现心律失常，其发生率与成年组相同，但青年组（7例）比成年组（2例）更常检测到严重室性心律失常。据认为，青年MVP患者的心律失常往往较为严重，但无任何症状和心脏功能障碍。
