ABSTRACT
Objective:
To observe the influence of sot alol on the QT dispersion in patients with atrioventricular accessory pathways u nderwent radiofrequency catheter ablation (RFCA).Methods:
Thirt y-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 intracar diac electrophysiological study was performed every 30 min for 5 times. Th e other group(control group, 18 cases) only treated by RFCA.QTd,QTcd and QTLcd w ere measured before and after RFCA.Results:
There was no signif icant 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; QT Lcd(30.8±14.1)ms vs (25.6±19.4) ms (P<0.05).Conclusion:
Sotalol can slightly lower QT dispersion, which is beneficial for preventing malignant ventricular arrthythmia. It is safe in RFCA in pateints with accessory pathway.
