本文通过食管程序电刺激,对20例阵发性室上性心动过速(简称室上速)患者,其中房室结内折返性心动过速(AVNRT)5例,房室折返性心动过速(AVRT)15例,研究静脉注射地尔硫或维拉帕米(0.2mg/kg)的即时疗效和电生理作用。结果表明:①两药均有明显抑制房室结传导作用,对旁路的传导无明显抑制;②对正常窦房结功能者无明显抑制作用;③单剂静脉注射时血压轻度降低,副作用轻;④终止诱发或自发性室上速的有效率分别为60%(地尔硫组)和80%(维拉帕米组)。
In this paper, esophageal electrical stimulation, 20 cases of patients with paroxysmal supraventricular tachycardia (AVSRT) in 5 cases, atrioventricular reentrant tachycardia (AVRT) in 15 patients were studied for immediate efficacy and electrophysiological effects of intravenous diltiazem or verapamil (0.2 mg / kg). The results showed that: ① both drugs significantly inhibited the conduction effect of atrioventricular node, the bypass conduction was not significantly inhibited; ② no effect on normal sinus node function; ③ a single intravenous injection of blood pressure was mildly reduced side effects Light; ④ The effective rate of termination of induced or spontaneous supraventricular tachycardia was 60% (diltiazem group) and 80% (verapamil group).
