心电图双峰T波在正常小儿和年轻人、失天性心脏病和低血钾等出现,多见于V_2～V_4导联。本院2,000例正常2月～12岁小儿在V_1、V_3导联双峰T波的发生率平均为10.9%,前峰大多高于后峰。100例45天～12岁室间隔缺损患儿心电图出现典型园顶(前峰)一尖角(后峰)双峰T波49例,后峰高于前峰。不典型园顶一尖角T波26例。手术时见缺损直径小于1cm者均未见双峰T波。肺动脉高压时双峰T波不典型或未见。17例术后复查.16例转为倒置。
ECG Bimodal T wave in normal children and young people, acquired heart disease and hypokalemia appeared more common in V_2 ~ V_4 lead. The average incidence of bimodal T wave in V_1 and V_3 leads was about 10.9% in 2,000 normal children from February to 12 years old in our hospital, and the former was mostly higher than the latter. In the electrocardiogram of 100 cases with ventricular septal defect of 45 days to 12 years old, there were 49 cases of double-peak T wave with apex (apex) and apex (apex). The posterior peak was higher than the anterior peak. Atypical peak of a sharp T wave 26 cases. Surgery see the defect diameter less than 1cm were not seen bimodal T wave. Pulmonary hypertension when the bimodal T wave atypical or not seen. Seventeen cases were retrospectively reviewed and 16 cases were reversed.
