Inclusion Criteria: 1. History of remote myocardial infarction 2. Left ventricular ejection fraction ≥ 30 to ≤ 50 % as estimated by cardiac MRI, 3D-echocardiography or via ventriculography within 30 days before enrollment 3. Documentation of sustained ventricular tachycardia (VT) by any kind of Electrocardiography (ECG) including 12 lead ECG, holter ECG, rhythm strip, event monitoring, event recorder or pacemaker within 30 days before enrollment 4. Implantable cardioverter-defibrillator (ICD) indication for secondary prevention 5. Patients who are planned to be implanted with BIOTRONIK ICDs (single, dual, triple chamber or DX device) 6. Patient has provided written informed consent 7. Patient accepts activation of Home Monitoring® Exclusion Criteria: 1. Age \< 18 years or \> 80 years 2. Known arterial or venous thrombosis 3.

Significant medical problem that in the opinion of the principal investigator would preclude enrollment in the study 16. Unwillingness to participate or lack of availability for follow-up 17. Participation in another interventional clinical investigation during the course of the study, i.e. the participation in a non-interventional clinical investigation is allowed.
