The prevalence of mitral-valve prolapse in 200 volunteers (100 men and 100 women) was investigated by means of a combination of clinical, phonocardiographic, and echocardiographic findings. Mitral valve prolapse was documented on M-mode echocardiography in four men and four women, giving an over-all prevalence of 4%. In addition, symptoms and electrocardiographic abnormalities, which are reported to occur more commonly in patients with mitral valve prolapse, occurred with equal frequency in the subjects with mitral valve prolapse and in those without prolapse.
通过综合临床、心音图和超声心动图检查结果，对200名志愿者（100名男性和100名女性）二尖瓣脱垂的患病率进行了调查。在M型超声心动图检查中，4名男性和4名女性被记录为二尖瓣脱垂，总体患病率为4%。此外，据报道在二尖瓣脱垂患者中更常见的症状和心电图异常，在有二尖瓣脱垂的受试者和没有脱垂的受试者中出现的频率相同。
