ABSTRACT
Objective To investigate the electrocardiographic(ECG) characteristics and assess the safety of radiofrequency catheter ablation (RFCA) of ventricular tachyeardia (VT), and frequent ventricular premature con- tractious(VPCs) originating from left ventricular outflow tract(LVOT). Methods Twelve-lead ECG analysis and RFCA were performed in 9 patient with VT or VPCs originating from LVOT. Results The sites to be successfully ablated were in left valsalva sinus in 6 patients,and subaortic valve in 3 patient. ECG revealed tall R wave in leads Ⅱ, Ⅲ ,aVF, V5 and V6. QS morphology in both leads aVR and aVL,QS morphology in lead Ⅰ in most cases. R wave in lead Ⅰ was relative tall, the R/S wave amplitude in lead V1 was over 0.62 ,and precordia R wave transition was irregular. All 9 patients were successfully ablated. No death or recurrenced case during follow-up. Conclusion Ventricular taehycardia and frequent ventricular premature rcontractions originating from left ventricutar outflow tract could be known by some specific ECG characteristics and could be radically treated safely by RFCA.
