1991年6月～1993年12月,我们收治20例经口服心律平或其他抗心律失常药半年以上无效的房颤患者。经心电图证实为持续性房颤18例,阵发性房颤2例。其中男18例,女2例;年龄为24～77岁;病因为冠心病18例,心肌炎2例,多因劳累、情绪激动、感染、饮酒等而诱发。 1.给药方法:胺碘酮0.2g,日2次;口服7～10天后复查心电图,转复为窦性心律者减至0.2g/d,维持量为0.1～0.2g/d,可连服半年左右。对口服半月无效者,可在心电图监测下继服半个月再减量。服药期间应密切观察,若心电图Q—T间期延长到0.55秒以上、心律<50次/min即停药或减量,
From June 1991 to December 1993, we treated 20 patients with atrial fibrillation who had been inactive for more than six months with oral arrhythmia or other antiarrhythmic agents. The electrocardiogram confirmed 18 cases of persistent atrial fibrillation, paroxysmal atrial fibrillation in 2 cases. Including 18 males and 2 females; aged 24 to 77 years; etiology of coronary heart disease in 18 cases, 2 cases of myocarditis, mostly due to exertion, agitation, infection, alcohol and so on induced. 1. Method of administration: amiodarone 0.2g, 2 times a day; 7 to 10 days after oral reexamination of ECG, converted to sinus rhythm were reduced to 0.2g / d, maintenance of 0.1 ~ 0.2g / d, even For six months or so. Oral half-moon ineffective, ECG monitoring can be followed for half a month and then reduce. During the medication should be closely observed, if the ECG Q-T interval is extended to 0.55 seconds or more, the heart rate <50 beats / min that withdrawal or reduction,
