Indications and Usage
St. Jude Medical™ ICDs and CRT-Ds are intended to provide ventricular antitachycardia pacing and
ventricular defibrillation for automated treatment of life-threatening ventricular arrhythmias.
AF Suppression™ pacing is indicated for suppression of paroxysmal or persistent atrial fibrillation in
patients with the above ICD indication and sinus node dysfunction.
In patients indicated for an ICD, CRT-Ds are also intended:
to provide a reduction of the symptoms of moderate to severe heart failure (NYHA Functional
Class III or IV) in those patients who remain symptomatic despite stable, optimal medical therapy
(as defined in the clinical trials section included in the Merlin PCS on-screen help) and have a left
ventricular ejection fraction less than or equal to 35% and a prolonged QRS duration
to maintain synchrony of the left and right ventricles in patients who have undergone an AV nodal
ablation for chronic (permanent) atrial fibrillation and have NYHA Class II or III heart failure
