报告5例心动过速患者6次电生理-药物试验(EPPT)结果。A组3例[2例室上性心动过速(SV7)与1例复发性持续性室性心动过速(RVT)]仅做了静注异搏定的急性药物试验,RVT患者间隔9月后复发而做了第2次EPPT;B组2例(1例SVT与1例RVT)做了持续一周的系列EPPT。EPPT不仅明确了各例心动过速发生的机理,而且找到了有效的治疗方法——有效的治疗药物和(或)有效的起搏终止心动过速的方式。
Five electrophysiological-drug test (EPPT) results were reported in 5 patients with tachycardia. Three patients in Group A [2 patients with supraventricular tachycardia (SV7) and 1 patient with recurrent persistent ventricular tachycardia (RVT)] were given only acute drug trials of intravenous verapamil. Patients with RVT had an interval of 9 months After the second episode of recurrence, EPPT was performed; two cases in group B (one case of SVT and one case of RVT) underwent continuous one-week EPPT. EPPT not only clarified the mechanism of occurrence of tachycardia in each case, but also found effective treatment methods - effective treatment of drugs and / or effective pacing termination of tachycardia way.
