摘要
本文对35例无临床器质性心脏病证据的室性心动过速患者进行了电生理检查及心室晚电位检查,并随访41.2±24个月。结果发现,临床表现为单形持续性室速者电程序刺激阳性率高(6/8),若不积极治疗,少数患者可能有猝死的危险。临床表现为非持续性室速者,电程序刺激及晚电位检查的阳性率均极低(分别为0/27和1/27)。我们认为,对于无临床器质性心脏病的持续性室速者,应进行电生理检查并筛选有效药物,给予抗心律失常治疗;而非持续性室逮不是电生理检查的适应证,对无症状者可不予治疗;对有症状者可对症治疗,其预后良好。
Thirty-five patients with ventricular tachycardia (VT) without clinical evidence of organic heart disease were evaluated and followed up for 41.2±24 months. It was found that the inducible rate of VT was higher in patients presenting sustained VT (6/8), and some of them may have sudden death if they were not treated properly. In patients with non-sustained VT, the inducible rate of sustained VT was 0/27, and the ventricular late potentials were positive only in oneout of 27 cases.
It is concluded that sustained VT, though without over heart disease, may be an indication of electrophysiological test, and suitable antiarrhythmic agents should he administered. While non-sustained VT may not be indicated for electrophysiological test. If patients with the latter kind of VT were asymptomatic, antiarrhythmics is not necessary.
