Abstract

The antiarrhythmic efficacy if low dose amiodarone treatment was studied in 30 cases of ventricular premature beats(VPBs). Amiodarone was administered 600mg daily in three divided doses for for initial 7-10 days as loadihg dosage,then 100-200mg once daily as maintenance. The results obtained were as follow :
1) The complete control of VPBs was achieved by amiodarone treatment in 90%, 27cases of 30 cases(all 11 cases with simple VPBs and 16 cases of the remainders with complex VPBs).
2) The QT interval and QTc were significantly prolonged, whereas heart rate was reduced significantly after amiodarone treatment.
3) In 27 cases of responder, the frequency of VPBs began to decrease overtly 2-3 days after amiodarone administration, then relatively stablized in 6 days, and complete cnotrol of VPBs was achieved in all cases about 10 days after treatment.
4) No significant side-reaction was observed except the decrease of serm T3 level after treatment.
