Interactions between two simultaneous tachycardias within an electrically isolated pulmonary vein.

abstract：INTRODUCTION:Epicardial catheter ablation is increasingly used to treat arrhythmias with an epicardial component. Nevertheless, percutaneous epicardial access remains associated with a significant risk of major complications. Developing a technology capable of confirming proper placement within the pericardial space co...
