单纯性Q-T间期延长病例时有报导,但合并错综T波者未见报告,现将我们见到的一例报告如下: 患儿,10岁,自幼身体欠佳,常患感冒,发热。2周岁起常因情绪激动或过累时出现晕厥。晕厥发作时心脏听诊:心动过缓,心脏停搏,即行胸外按压而复律,但心律不齐。当描记心电图时心律已较均齐。心房率为84次/分,心室率为42次/分。P-R间期固定为0.17秒,P与QRS呈2:1传导。Q-T间期为0.73秒T波在各导联均为双峰而且后峰窄并高
There are reports of simple Q-T prolongation cases, but there are no reports of complicated T-waves. We report the following one case: Children, aged 10, who are in poor health and often have a cold and fever. 2 years old often because of agitation or tired when syncope occurs. Syncope heart auscultation: bradycardia, cardiac arrest, chest compression and cardioversion, but arrhythmia. Heartbeat was more homogeneous when electrocardiogram was traced. Atrial rate was 84 beats / min, ventricular rate was 42 beats / min. P-R interval was fixed at 0.17 seconds, P and QRS were 2: 1 conduction. The Q-T interval is 0.73 seconds The T-wave is bimodal in each lead and the back peak is narrow and high
