Summary

The purpose of this study is to determine how the position of the right ventricular (RV) coil of an implantable cardioverter defibrillator (apex versus septum) affects the defibrillation threshold; specifically, can defibrillator threshold be improved by implantation site selection.

Detailed description

The investigators propose a prospective, pseudo-randomized study of patients who are electing to undergo implantation of an implantable cardioverter defibrillator (ICD). There are two locations in the heart in which ICDs are normally implanted: the apex and the septum. The purpose of this study is to determine whether the ICD performs better in one location or the other, as measured by defibrillation threshold. In this study, both locations will be tested in each patient. The final location will be determined by the implanting physician as the location that is best for the patient.

Conditions

• Ventricular Tachycardia
• Ventricular Fibrillation

Interventions

Type	Name	Description
PROCEDURE	Implantable Cardioverter Defibrillator (ICD)	Patients will receive an Implantable Cardioverter Defibrillator (ICD), with the leads implanted in either the apex or the septum as the first location. After defibrillation threshold is determined, the leads position will be changed to the second location and DFT will be determined again.
