The purpose of this study is to collect information about how safe Dual Energy THERMOCOOL SMARTTOUCH™ SF (DE STSF) catheter with TRUPULSE™ Generator is and how effective a specific procedural workflow is when this ablation system is used to treat ventricular arrhythmias. The main aims of this study are to see whether the abnormal heart rhythm can be successfully treated while maintaining a specific procedural workflow with the catheter and generator during the cardiac ablation and to monitor participant safety after the procedure by checking if the participant has any complications.
