Effect of T-Wave Dispersion on ULV and DFT/ A method of device testing during ICD generator changes or new ICD or Biventricular ICD implants. (partial support - Medtronic)

For more information, speak with your EP MD prior to upgrade, implant or generator change

Analysis of Extracted Pacemaker and ICD Lead-Derived Tissue. The purpose of this study is to understand the cellular, molecular and physical properties of tissue derived from extracted pacemaker and ICD leads.

For more information, speak with your EP MD prior to lead extraction.

Hansen Trial- clinical trial using the Hansen robot versus manual positioning of the ThermoCool catheter in Atrial Fibrillation Ablations. The purpose is to asses the safety and performance of the robotic system during Atrial Fibrillation Ablations.

Decision Making in Implantable Defibrillator Treatment / The purpose of this survey study is to understand the decision making process of patients prior to being implanted with a cardiac defibrillator.

For more information, speak with your EP MD prior to new implant of ICD

EP Suite Protoype for X-Ray based device.

For more information, speak with your EP MD prior to your procedure.
