Abstract
Aims To investigate the characteristics of bipolar intracardiac electrograms (bi-EGMs) in target sites of ventricular arrhythmias (VAs) originating from the distal great vein system (DGCVs).
Methods 169 patients undergoing first-time ablation for VAs originated from DGCVs were enrolled in present study. Successful ablation was achieved in 146 patients. Bi-EGMs on successful sites were recorded and analyzed.
Results In the 146 cases, the DGCVs...
