Evidence Checklist: Supraventricular Tachycardia

ECG or Holter monitor capturing SVT episodesCritical

Electrocardiogram or ambulatory monitor documenting narrow-complex tachycardia, confirming SVT type (AVNRT, AVRT, atrial tachycardia) and episode frequency. Objective rhythm documentation is essential.

Electrophysiology (EP) study results

EP study documenting inducible SVT, ablation target, and procedural outcome. If ablation was performed, EP records confirm the arrhythmia mechanism.

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

A medical opinion connecting SVT to service-connected hypertension, thyroid disease, stimulant use during service, or other in-service cause.

Exercise stress test with METs estimationCritical

Stress test documenting functional capacity in METs, which drives the cardiac rating percentage. Also documents exercise-induced SVT if present.

Treatment records (medications, ablation, cardioversion)

Records of rate/rhythm control medications, ablation procedures, electrical cardioversion, and treatment response.

Episode frequency and duration log

Personal or medical log documenting SVT episode frequency, duration, and associated symptoms (palpitations, lightheadedness, presyncope, chest pain). Episode burden supports rating level.

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.

Completed DBQ Heart ConditionsCritical

Standardized form capturing arrhythmia documentation, METs, ejection fraction, and functional limitations from SVT.

Service treatment records (STRs)Critical

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