Abstract:
Objective: To observe the influence of sotalol on the QT dispersion in patients with atrioventricular accessory pathways underwent radiofrequency catheter ablation (RFCA). Methods: Thirty six patients were divided into 2 groups by random. One was the drug group(18 cases) treated by RFCA, and sotalol 160 mg was orally administered and intracardiac electrophysiological study was performed every 30 min for 5 times. The other group(control group, 18 cases) only treated by RFCA.QTd,QTcd and QTLcd were measured before and after RFCA. Results: There was no significant difference with QT dispersion before and after RFCA in control group. When compared with before RFCA, QTd in patients administered sotalol was (30.9?14.3) ms vs (24.7?9.6) ms; QTcd(33.7?17.1) ms vs (25.2?10.1) ms; QTLcd(30.8?14.1)ms vs (25.6?19.4) ms ( P
