Brief Summary
The purpose of this study is to identify markers of increased risk for incident ventricular arrhythmias and cardiovascular events in patients already being treated with an implantable cardioverter-defibrillator (ICD) by exploring patient history and clinical findings, biological markers, ECG markers, and echocardiographic markers.

Outcome Measures
Primary Outcomes (1)
Episodes of ventricular fibrillation (VF) or ventricular tachycardia (VT) resulting in appropriately delivered ICD therapies (including antitachycardia pacing) or sustained ventricular tachyarrhythmia (>100/min, >30sek).
Registered from the monitoring function of the ICD
Duration of follow-up will be a minimum of 180 days following inclusion of the final patient.
Secondary Outcomes (8)
All-cause mortality
Duration of follow-up will be a minimum of 180 days following inclusion of the final patient.
Cardiovascular mortality
Duration of follow-up will be a minimum of 180 days following inclusion of the final patient.
Major adverse cardiac event (MACE), i.e. acute myocardial infarction, stroke, urgent myocardial revascularization and cardiovascular mortality
Duration of follow-up will be a minimum of 180 days following inclusion of the final patient.
Heart failure hospitalization
Duration of follow-up will be a minimum of 180 days following inclusion of the final patient.
The combination of cardiovascular mortality and heart failure hospitalizations
Duration of follow-up will be a minimum of 180 days following inclusion of the final patient.

Eligibility Criteria
Patients treated with an ICD. Inclusion from outpatient clinic.
You may qualify if:
- Patients ≥ 18 years old
- Current treatment with an ICD
- Signed written informed consent before study commencement
You may not qualify if:
- Participation in other interventional clinical trial or previously included in the current study
- Patients not able to provide written informed consent
- Known or suspected, non-curable cancer,
- Neurological condition with short life expectancy; e.g. amyotropic lateral sclerosis (ALS)
- Patients unwilling or unable to comply with the protocol
- History of non-compliance to medical management and patients who are considered potentially unreliable by the Investigator
- History or evidence of alcohol or drug abuse with the last 12 months that may influence the participation of the patient in the study, as assessed by the Investigator during the screening phase
- Any surgical or medical condition, which in the option of the Investigator, will impair the ability of the patient to participate in the study
