Synchronized electrical countershock is an intriguing new method for the treatment of ectopic tachycardias. The authors applied this treatment to 20 patients with chronic atrial fibrillation and, in 17 patients, sinus rhythm was restored immediately. An additional four patients with atrial flutter were successfully converted to sinus rhythm. One patient developed a hemiplegia two weeks after cardioversion. No other untoward side effects were observed. In two patients with ventricular fibrillation electrical countershock terminated the arrhythmia. After successful cardioversion of atrial fibrillation, a maintenance dose of quinidine is given to help maintain sinus rhythm. In spite of this precaution, one-half of the patients reverted to atrial fibrillation within a month. The quinidine was administered for two to three days in advance of cardioversion; on this regimen, 10 of 34 patients reverted to sinus rhythm on quinidine alone and did not require countershock. The exact place of this treatment of cardiac arrhythmias has not yet been clearly defined.
同步电复律是一种用于治疗异位性心动过速的有趣新方法。作者将这种治疗方法应用于20例慢性心房颤动患者，其中17例患者立即恢复了窦性心律。另外4例心房扑动患者成功转为窦性心律。1例患者在心脏复律两周后出现偏瘫。未观察到其他不良副作用。2例心室颤动患者经电复律终止了心律失常。心房颤动成功复律后，给予维持剂量的奎尼丁以帮助维持窦性心律。尽管采取了这一预防措施，但仍有一半的患者在一个月内恢复为心房颤动。在复律前提前两到三天给予奎尼丁；采用这种方案，34例患者中有10例仅使用奎尼丁就恢复了窦性心律，无需进行复律。这种治疗心律失常的方法的确切地位尚未明确界定。
