二尖瓣脱垂(MVP)患者的一般症状多与植物神经功能和代谢紊乱有关。通过运动锻练调节生理和心理因素,可望减少症状发生的频度和程度。 38名女性(其中有6名因故中断试验)年龄21～49(平均34)岁。有症状时间均在1年以上,每周出现症状至少1次。全部患者均可闻及易变的非喷射性收缩期喀喇音,部分伴收缩中、晚期杂音。诊断均经M型或二维超声心动图证实。患者随机分为运动组和对照组。试验观察为期12周,运动组患者每周运动3次。耗氧运动锻练(aerobic exercise training)按美国心脏学会制定的心脏康复方案第二期要求进行。作功负荷强度以达到极量运动心率
The general symptoms of patients with mitral valve prolapse (MVP) are mostly associated with autonomic function and metabolic disorders. Adjusting physical and psychological factors through exercise training is expected to reduce the frequency and extent of symptoms. Thirty-eight women (six of whom were interrupted for some reason) were 21-49 (mean, 34) years old. Symptomatic time in more than 1 year, weekly symptoms at least 1 times. All patients can smell and variable non-jet systolic Kara tone, some with shrinkage, late murmur. Diagnosis were confirmed by M-mode or two-dimensional echocardiography. Patients were randomly divided into exercise group and control group. The experimental observation period of 12 weeks, exercise group patients exercise three times a week. Aerobic exercise training is based on the second phase of the Cardiac Rehabilitation Program developed by the American College of Cardiology. Work load intensity to achieve extreme exercise heart rate
