Implantable Defibrillator:

Cameron Health's S-ICD System:
delivers a jolt through a sensor
implanted under a patient's skin, but
not wired to a patient's heart.

Implantable Cardioverter Defibrillators
(ICDs) provide a shock or pacing
therapy to bring back a normal heart
beat when a patient experiences a
dangerous abnormal heart rhythm
such as ventricular tachycardia (VT).
ICDs are very successful in bringing
back a normal heart beat when VT
occurs, but they do not prevent further
dangerous heart rhythms from

This study is designed to determine
the best way to manage patients who
have an ICD and who continue to have
episodes of VT. There are two
methods for treatment the VT: 1)
Ablation, and 2) Medication.
An ablation procedure involves placing
a flexible catheter (insulated wire) in
the groin area and threading it into the
heart. After the doctor has located the
affected area responsible for the VT,
radiofrequency energy is delivered by
the power generator through the
catheter to the inside of the heart. The
radiofrequency energy ablates (burns)
a small area of the heart tissue
thought to cause the VT.

A medication called Amiodarone is an
"anti-arrhythmic" prescribed to prevent
abnormal heart rhythms from recurring.

The purpose of this study is to
compare these two different methods
for treating VT.
