Outcome Measures
Primary Outcomes (1)
Number of participants with implantable cardioverter defibrillator (ICD) related adverse events
ICD related adverse events are defined as inappropriate shocks and/or implant-, lead- and device related complications. An inappropriate shock is shock therapy for anything else but ventricular fibrillation or ventricular tachycardia. Implant related complications are defined as ICD related infections, ICD related bleedings, thrombotic events, need for lead reposition, post-implant pneumothorax, post-implant hematothorax, or post-implant perforation/tamponade. Lead- or device related complications are all complications related to the lead or device.

Eligibility Criteria
You may qualify if:
- Patients 18 years and older
- Patients with class I or IIa indication for ICD therapy according to the ACC/AHA/ESC 2006 Guidelines for Management of Patients With Ventricular Arrhythmias and the Prevention of Sudden Cardiac Death
You may not qualify if:
- Patients with documented therapy refractory monomorphic ventricular tachycardia
- Patients having an indication for pacing therapy
- Patients with ventricular tachycardia less than 170 bpm
- Patients failing appropriate QRS/T-wave sensing with the S-ICD ECG patient screening tool provided by Cameron Health/Boston Scientific
- Patients with incessant ventricular tachycardia
- Patients with a serious known concomitant disease with a life expectancy of less than one year
- Patients with circumstances that prevent follow-up (no permanent home or address, transient, etc.)
- Patients who have had a previous ICD implant
- Patient who receive cardiac contractility modulation therapy or are likely to receive cardiac contractility modulation therapy.
- Patients who are unable to give informed consent
