Brief Summary:
This retrospective multicenter cohort will validate an independent association of electrocardiographic (ECG) global electrical heterogeneity (GEH) measures with sustained ventricular tachyarrhythmias and appropriate ICD therapies in systolic heart failure patients with primary prevention ICD, and will validate and re-calibrate GEH ECG risk score for prediction of sustained ventricular tachyarrhythmias and appropriate ICD therapies in systolic heart failure patients with primary prevention ICD.

Primary Outcome Measures :
- Primary outcome: sustained VT/VF event with appropriate ICD therapy (either ATP or shock) [ Time Frame: up to 15 years ]Sustained ventricular tachyarrhythmia event with appropriate ICD therapy (either antitachycardia pacing or shock)
- Primary competing outcome: All-cause death without preceding sustained VT/VF with appropriate ICD therapy [ Time Frame: up to 15 years ]All-cause death without preceding sustained ventricular tachyarrhythmia with appropriate ICD therapy
Secondary Outcome Measures :
- sustained monomorphic ventricular tachycardia [ Time Frame: up to 15 years ]Sustained monomorphic ventricular tachycardia with appropriate ICD therapies (either antitachycardia pacing or ICD shock)
- sustained polymorphic ventricular tachycardia / ventricular fibrillation [ Time Frame: up to 15 years ]sustained polymorphic ventricular tachycardia or ventricular fibrillation with appropriate ICD therapies (either antitachycardia pacing or ICD shock)

Study Population
retrospective records of systolic heart failure patients with primary prevention ICDs/CRT-Ds implanted for routine clinical indications
Criteria
Inclusion Criteria:
- records of systolic heart failure patients with primary prevention ICDs/CRT-Ds implanted for routine clinical indications
Exclusion Criteria:
- absent baseline pre-implant digital ECG;
- missing data on clinical predictors and covariates;
- missing ICD programming data (including number of intervals to detect [NID] or time to detect, number of detection zones, heart rate for each detection zone, and anti-tachycardia pacing [ATP] programming);
- missing outcomes data.
- records of patients with inherited channelopathies (e.g. long QT syndrome, Brugada syndrome), inherited cardiomyopathies (e.g. hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy), and congenital heart disease.
