心电图U波倒置早有报告,但多是与冠心病、高血压病、主动脉瓣关闭不全、心肌病等左室疾病有关,而右室疾病时U波倒置的报告较少。Furbtta曾描述过先天性心脏病时,Ⅲ、aVF及右胸导联可见U波倒置。盐见氏报告了15例V_1导联U波倒置的研究结果,显示U波倒置出现时除右室肥大外多伴有明显的右室收缩压力增高(114.1±26.4mmHg),因此提出在先天性心脏病的患者中,U波倒置是提示反向分流的重要的心电图所见。
ECG U wave inversion has been reported, but mostly with coronary heart disease, hypertension, aortic regurgitation, cardiomyopathy and other left ventricular disease, and right ventricular disease U wave inversion report less. Furbtta had described congenital heart disease, Ⅲ, aVF and right chest lead visible U wave inversion. Yan Jianshi report of 15 cases of V-lead U-wave inversion results show that U-wave inversion occurs in addition to more than right ventricular hypertrophy accompanied by significant increased right ventricular systolic pressure (114.1 ± 26.4mmHg), it is proposed in the congenital In patients with heart disease, U-wave inversion is an important ECG that suggests reverse shunting.
