阵发性室上性心动过速,是临床上常见的一种症状。一般采用刺激迷走神经的机械方法,如用迷走神经兴奋药、升压药、毛地黄制剂、以及奎尼丁、β肾上腺素能受体阻滞剂等措施,能使其终止发作。最近我们遇到二例顽固性室上性心动过速,综合使用上述方法无效,而用小剂量异搏停静脉滴入,获得满意效果。现报告如下: 病例摘要例1.男性、50岁医院干部。主诉:阵发性心悸已三年余。患者于1976年8月21日晚上在书案上写字时,突然感到心悸、胸闷、脉率达200余次/分,半小时后发作自行终止,终止后患者无自觉不适。此后有类似间断性发作,持续时间自几分钟到几小时,心电图检查示室上性心动过速,发作时能用刺激迷走神经及口服安定使其控 Paroxysmal supraventricular tachycardia, is a common clinical symptoms. The general use of mechanical methods to stimulate the vagus nerve, such as the vagus nerve stimulant drugs, vasopressors, hair yellow preparations, and quinidine, β-adrenergic receptor blockers and other measures, can make it stop the attack. Recently, we encountered two cases of intractable supraventricular tachycardia, the combined use of the above method is invalid, but with a small dose of verapamil intravenously, to obtain satisfactory results. Now report as follows: Case Summary 1. Male, 50-year-old hospital cadres. Chief complaint: paroxysmal palpitations have more than three years. When the patient wrote the book on the night of August 21, 1976, he suddenly felt palpitations and chest tightness with a pulse rate of more than 200 beats / min. After half an hour, the patient stopped his own seizure and stopped without conscious discomfort. After a similar intermittent seizure, duration from a few minutes to several hours, ECG showed supraventricular tachycardia, attack can stimulate the vagus nerve and oral stability to its control
