Abstract

Aim: The study defines criteria for localization of ventricular arrhythmias. Materials & methods: Data from 40 premature ventricular complex (PVC)/ventricular tachycardia (VT) were studied. The interval from PVC QRS onset to His potential and ratio of this interval to PVC/VT QRS duration was analyzed. Patients were divided into epicardial and endocardial groups based on mapping/successful ablation site. Results: The interval from PVC QRS onset to His potential in the epicardial versus endocardial group was 99 ± 21 ms and 64 ± 37 ms (p = 0.002). A cut off of 88 ms had a sensitivity of 73% and specificity of 76%. A cut off of 0.50 for the ratio had a sensitivity of 82% and specificity of 72%. Conclusion: Two new parameters can help localization of PVC/VTs origin.
