Abstract

From January 1996 to May 2002, 61 patients with ventricular tachycardia from right ventricular outflow tract were referred to Siriraj hospital. All patients underwent clinical examination, Doppler echocardiography and electrophysiologic study. Mapping of ventricular tachycardia was performed by activation mapping and pacemapping. There were 44 females and 17 males with an average age of 41.7 +/- 9.9 years. Presenting symptoms were palpitation (95.1%), presyncope (39.3%), and syncope (26.2%). Six patients were found to have underlying cardiac disease. Radiofrequency catheter ablation was successful in 56 patients (91.8%). There were no major complications. Seven patients (12.5%) had recurrent ventricular tachycardia. Five of them were successfully reablated. The authors concluded that radiofrequency ablation is an effective treatment in patients with ventricular tachycardia from right ventricular outflow tract.

摘要

1996年1月至2002年5月，61例右心室流出道室性心动过速患者被转诊至诗里拉吉医院。所有患者均接受了临床检查、多普勒超声心动图检查和电生理研究。通过激动标测和起搏标测对室性心动过速进行标测。有44名女性和17名男性，平均年龄为41.7±9.9岁。主要症状为心悸（95.1%）、先兆晕厥（39.3%）和晕厥（26.2%）。6例患者被发现有潜在的心脏疾病。56例患者（91.8%）射频导管消融成功。无重大并发症。7例患者（12.5%）出现室性心动过速复发。其中5例再次成功消融。作者得出结论，射频消融是治疗右心室流出道室性心动过速患者的有效方法。
