本文报道23例急性氯化钡中毒的心电图动态观察,除窦性心动过缓、窦性心律不齐及典型低血钾症各占21.78％、47.8％和13.04％外,发现T波高耸占56.52％,其T波形状高大,基底不窄,QT间期不缩短,同时测血清钾多低于正常,T波平均复原时间为13天,拟为钡直接对心肌损害使心内膜下心肌复极迟缓之故。 This article reports 23 cases of acute barium chloride electrocardiogram dynamic observation, in addition to sinus bradycardia, sinus arrhythmia and typical hypokalemia accounted for 21.78%, 47.8% and 13.04%, and found that T wave towering 56.52 %, The T wave shape is tall, the base is not narrow, the QT interval is not shortened, while serum potassium is lower than normal, T wave average recovery time is 13 days, intended for direct myocardial damage to myocardial submucosal complex Very late therefore.
