摘要
选择心电图有非对称性倒置T波伴终末正向过度突出(PTO)的14岁以上心脏病患者66例,排除了束支传导阻滞、心肌梗塞及服用洋地黄类药物者,对照其超声心动图、x线平片及心室造影资料,均见有两项以上示左或右室璧增厚及/或心室腔扩大,认为PTO可作为诊断左室或右室肥大的“电压标准”的一个补充指标。
Sixty-six cases with asymmetrically inverted T wave and positive terminal overshoot (asymmetry ratio of 2.0 or greater) were studied. Patients with ischaemic heart disease, bundle-branch block or taking cardiac glycosides were excluded. The hearts were examined by echocardiography, X-ray plain film and ventriculography. It was found that all the 66 cases had left or right ventricular hypertrophy and / or dilatation. In 6 of 22 patients with left ventricular enlargement and in 10 of 44 patients with right ventricular enlargement, the electrocardiogram did not satisfy the traditional voltage criterion of left or right ventricular enlargement respectively. T wave asymmetry ratio of 2.0 or more may be regarded as an additional parameter of ventricular hypertrophy or dilatation.
