To study the incidence and nature of cardiac arrhythmias and the changes in the corrected Q-T interval, 60 patients with the prolapsed mitral valve syndrome were examined. All the patients underwent resting ECG and leg isometric exercise. 24-hour ECG monitoring was performed in 48 patients. The latter technique was found to be the most informative tool for detecting cardiac arrhythmias (66.8%). Prolonged corrected Q-T interval (more than 440 msec) was more frequently revealed in leg isometric exercise (41.6%) than in resting ECG (26.6%) and 24-hour monitoring (29.2%). Its degree was directly related to the severity of cardiac arrhythmias in patients with the prolapsed mitral valve syndrome.
为研究心律失常的发生率、性质以及校正Q-T间期的变化，对60例二尖瓣脱垂综合征患者进行了检查。所有患者均接受静息心电图和腿部等长运动检查。48例患者进行了24小时心电图监测。发现后一种技术是检测心律失常最有效的工具（66.8%）。腿部等长运动时校正Q-T间期延长（超过440毫秒）的发生率（41.6%）高于静息心电图（26.6%）和24小时监测（29.2%）。其程度与二尖瓣脱垂综合征患者心律失常的严重程度直接相关。
