收缩晚期杂音伴有或不伴有非喷射性喀喇音常伴有二尖瓣脱垂和不同程度的二尖瓣返流。晚近,有些作者发现这类患者中有左心室收缩末期形态异常,提示有原发性心肌疾病。作者等亦发现左室功能失调的发生率很高,常在运动应激时出现。本文报告26例患者(女20例,男6例;平均年龄41岁),均示有左室功能失调。方法:26例患者除听诊有收缩期喀喇音及/或收缩晚期杂音外,尚有心律失常或严重胸痛。心脏大小借后前位及侧位胸片测定,各别心室的增大则用吞钡法从四个位置
Contraction of late murmur with or without non-jet coronal sound associated with mitral valve prolapse and varying degrees of mitral regurgitation. Recently, some authors found that this type of patients have abnormal morphology of the terminal ventricular end-systolic, suggesting primary myocardial disease. The authors also found that the incidence of left ventricular dysfunction is high, often in exercise stress occurs. This article reports 26 patients (20 females, 6 males; mean age 41 years), all showed left ventricular dysfunction. Methods: Twenty-six patients had arrhythmia or severe chest pain in addition to auscultation with systolic and / or contracting late murmur. After the size of the heart by the chest before and after determination, the individual ventricular enlargement is to use barium from four positions
