Evidence Checklist: Ventricular Arrhythmia

ECG and Holter monitor documenting ventricular arrhythmia typeCritical

Electrocardiogram and 24-48 hour Holter monitor confirming ventricular arrhythmia: PVCs (premature ventricular contractions), non-sustained VT, sustained VT, or ventricular fibrillation. Episode frequency and duration are critical.

Echocardiogram with ejection fractionCritical

Echocardiography documenting EF and structural heart disease (cardiomyopathy, prior MI) that is the substrate for ventricular arrhythmia. EF below 35% typically triggers ICD implantation.

Nexus opinion linking ventricular arrhythmia to service ("at least as likely as not")Critical

A medical opinion connecting ventricular arrhythmia to service-connected cardiomyopathy, prior MI, ischemic heart disease, toxic exposure, or other in-service cardiac condition.

Exercise stress test with METs (if safe to perform)Critical

Stress test documenting functional exercise capacity in METs — the primary driver of the heart condition rating percentage. May include exercise-induced arrhythmia documentation.

Electrophysiology (EP) study and ablation records

EP study documenting inducible VT, VT origin, and ablation procedures. Documents arrhythmia mechanism and treatment history.

ICD (implantable cardioverter-defibrillator) records and shock logCritical

ICD implant records, device interrogation reports, and ICD shock log documenting appropriately-treated ventricular arrhythmia episodes. ICD shock data is powerful objective evidence of life-threatening arrhythmia.

Buddy statement from spouse, family, or fellow service member

A written statement from someone who can describe observable symptoms and how your condition affects daily life.

Personal statement describing symptoms and functional impact

Your own written account of how this condition affects your daily activities, work, and relationships. Describe your worst days.

Completed DBQ Heart ConditionsCritical

Standardized form capturing arrhythmia type, ECG/Holter findings, ICD records, METs, ejection fraction, and functional limitations from ventricular arrhythmia.

Service treatment records (STRs)Critical

Military medical records showing in-service treatment, complaints, or injuries related to this condition.
