- Patients with known ICD lead problem (lead dislodgement)
ICD without the following characteristics :
- data logging function with cumulative counting of device intervention (shocks and anti-tachycardia pacing [ATP])
- electrogram storage capabilities
- ventricular demand pacing.
- Recent unstable angina pectoris or myocardial infarction (< 4 weeks),
- History of torsades de pointes,
- Genetic channelopathies including congenital long QT syndrome,
- Wolff-Parkinson-White syndrome,
- Patients in unstable hemodynamic condition such as acute pulmonary edema within 12 hours prior to start of study medication; cardiogenic shock; treatment with intravenous pressor agents; patients on respirator; congestive heart failure of stage New York Heart Association (NYHA) IV within the last 4 weeks; uncorrected, hemodynamically significant primary obstructive valvular disease; hemodynamically significant obstructive cardiomyopathy; a cardiac operation or revascularization procedure within 4 weeks preceding randomization,
- Incessant sustained VT/VF (VT/VF that recurs promptly despite termination attempts) during the three days preceding randomization.
- Patients with inappropriate (not triggered by VT nor VF) shocks during the month preceding randomization.
- Clinically relevant haematologic, hepatobiliary (ALT, AST > 3 times the upper limit of normal at randomization), gastro-intestinal, renal (serum creatinine > 221 µmol/l (2.5 mg/dl) at randomization), pulmonary, endocrinologic or psychiatric disease.
- Patients treated with oral amiodarone (more than 20 tablets during the 2 months preceding randomization)
