近年我们遇到两例心电图呈典型的右心室肥大,实为左心室肥大。即“假性心电图右心室肥大”。例一:男、68岁,因慢性左心衰竭于1985年6月入院。有不典型心绞痛史。检查:心界向左下扩大。心尖部可闻及Ⅲ级收缩期杂音。心电图如图1示右心室肥大、悬垂心。B超检查,右心室14～16mm,左心室60～61mm,二尖瓣脱垂,胸片示左心室扩大。血脂偏高。诊断冠心病,故其心电图的右心室肥大为假象,实为左心室肥大引起。
In recent years, we encountered two cases of typical ECG right ventricular hypertrophy, in fact, left ventricular hypertrophy. That is, “pseudo-ECG right ventricular hypertrophy.” Example 1: Male, 68 years old, admitted to hospital in June 1985 due to chronic left heart failure. Have a history of atypical angina. Check: heart to expand to the left. Apex can be heard and Ⅲ systolic murmur. ECG shown in Figure 1 right ventricular hypertrophy, hanging heart. B-ultrasound, right ventricular 14 ~ 16mm, left ventricular 60 ~ 61mm, mitral valve prolapse, chest X-ray showed ventricular enlargement. High blood lipids. Diagnosis of coronary heart disease, so the right ventricular hypertrophy of the ECG as a false impression, in fact, caused by left ventricular hypertrophy.
