严重室内传导障碍时应用洋地黄尚有争论,某些作者认为是反指征。本文报道43例患者,分为2组:第1组9例,均为男性,平均70岁(55～79岁),心电图示双束支阻滞,各例静脉注射西地兰(8例0.8mg,1例1.6mg),同时在注射前和注射后1小时作希氏束电图测定HV间期。第2组34例,平均72岁(55～85岁),心电图示完全性右束支和左前分支阻滞。因心力衰竭或室上性心动过速而应用洋地黄;同时临床和心电图观察16个月。结果是第1组在注射洋地黄后观察60分钟,HV
There are still controversies about the use of digitalis in severe intrahepatic conduction disorders, which some authors consider anti-indications. This article reports 43 patients, divided into two groups: the first group of 9 patients were male, average 70 years (55 to 79 years), ECG showed double bundle branch block, each case of cedilanid (8 cases 0.8 mg, and 1 patient, 1.6 mg). Simultaneously, HV interval was measured before and 1 hour after injection. The second group of 34 patients, mean 72 years (55 to 85 years), ECG complete right bundle branch and left anterior branch block. Digitalis was applied due to heart failure or supraventricular tachycardia; clinical and ECG were observed for 16 months. The result was Group 1 observed for 60 minutes after injection of digitalis, HV
