Abstract:
Objective To evaluate the electrocardiographic(ECG)characteristics and results of radiofrequency catheter ablation(RFCA)of idiopathic ventricular tachycardia or premature ventricular contractions(VT/PVCs)originating in the vicinity of atrioventricular annulus.Methods Nineteen patients with idiopathic VT/PVCs underwent conventional electrophysiological study and RFCA were included in this analysis.The 12 lcads(ECG)characteristics were also analyzed.Results The VT/PVCs were originated in the vicinity of mitral annulus in 10 cases,including anterolateral(n=5),postemlateral(n=3)and posteroseptal(n=2).The VT/PVCs were originated in the vicinity of tricuspid annulus in the rest 9 cases,including the free wall(n=5)and the septal portion(n=4).The 12-lead ECG patterns of VT/PVCs originating in the vicinity of atrioventricular annulus were helpful for determine the site of RFCA.The Vr/PVCs were successfully eliminated by RFCA in all cages.Conclusion The exact origin of VT/PVCs originating in the vicinity of atrioventricular annulus could be determined by 12.1eads ECG analysis and can be successfully and safely cured by RFCA.
