本文比较40例多个室间隔缺损与52例单个高位室间隔缺损的临床、血液动力学和治疗。90％的多个室间隔缺损及85％的单个室间隔缺损年龄均在1岁以下。两组病例的临床症状和体征,特别是全收缩期杂音的位置、传导及舒张中期杂音的出现均相同。所有病例的胸片均示有心脏扩大、肺动脉段凸出及肺部充血。37例(93％)多个室间隔缺损及47例(90％)单个室间隔缺损的心电图呈现异常。多个室间隔缺损中16例(40％)呈电轴左偏,而单个室间隔缺损则仅5例(10％)(P<0.01)。多个室间隔缺损呈电轴左偏者很少伴有左心室肥厚、完全性右束支传导阻滞及I度房室传导阻滞。7例多个室间隔缺
This article compares the clinical, hemodynamic, and treatment of 40 multiple ventricular septal defects with 52 single-ventricular septal defects. Ninety percent of multiple ventricular septal defects and 85% of single ventricular septal defects are under 1 year of age. The clinical symptoms and signs of both groups, especially the location of all-systolic murmur, and the presence of mid-conduction and diastolic murmurs were identical. In all cases, chest radiographs showed enlarged heart, prominent pulmonary artery segments and pulmonary congestion. 37 (93%) multiple ventricular septal defects and 47 (90%) single ventricular septal defects ECG abnormalities. Sixteen patients (40%) with multiple ventricular septal defects showed left-sided electromyography and only five patients (10%) with single ventricular septal defect (P <0.01). Multiple left ventricular septal defect axial deviation is rarely accompanied by left ventricular hypertrophy, complete right bundle branch block and I degree atrioventricular block. Seven cases of multiple ventricular septal defect
