Radiofrequency catheter ablation in frequently single premature ventricular beats / 中国基层医药

ABSTRACT

Objective To discuss curative effect about radio frequently catheter ablation(RFCA) in frequently single originating premature ventricular beats.Methods 19 patients with frequently single original premature ventricular beats.The site of orgin was determined by activation mapping for the earliest endocardial activation,and by pace mapping for the exact QRS pacing site.Results 18 patients operation obtained immediate success,1 patient was failure,but no complication happened.After RFA in 2 weeks 24 hour Hoter ECG was used to examine arrhythmia condition,and all cases were follow up for 6～24 months after RFA,there were 17 patients who had no recurrence or phenomenon of premature beats augument,1 patient showed other type premature ventricular bearts.Conclusion It is safe and effective about RFA in frequently single origin premature ventricular beats of outflow lane.
