Supraventricular Tachycardia (SVT) Secondary to Hyperthyroid Heart Disease
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Supraventricular Tachycardia (SVT) when it develops after Hyperthyroid Heart Disease.
Why Supraventricular Tachycardia (SVT) Is Linked to Hyperthyroid Heart Disease
Thyroid hormone excess
Primary condition · VASRD 7008
Hyperthyroid Heart Disease
Hyperthyroid heart disease is cardiac impairment specifically caused by an overactive thyroid, where excess thyroid hormone overworks the heart, distinct from hyperthyroidism's other symptoms like weight loss or anxiety. Because this code requires showing the cardiac impact specifically, evidence connecting your thyroid diagnosis to actual heart findings is essential.

Supraventricular Tachycardia (SVT)
Supraventricular tachycardia is an abnormally fast heart rhythm arising above the ventricles. The schedule names atrial fibrillation, atrial flutter, sinus tachycardia, atrial tachycardia, junctional tachycardia, multifocal atrial tachycardia, and several reentrant tachycardias among its examples. What sets the rating is not how often you feel an episode but how many treatment interventions the rhythm required over a year — or, at the lower tier, whether it is controlled by continuous oral medication or by vagal maneuvers. Both tiers open with confirmation by ECG.
Supraventricular Tachycardia (SVT) VA Rating Tiers
The VA rates Supraventricular Tachycardia (SVT) the same way whether it's claimed directly or as secondary to Hyperthyroid Heart Disease — severity of Supraventricular Tachycardia (SVT) itself determines the percentage.
Example combined rating
30% Hyperthyroid Heart Disease + 30% Supraventricular Tachycardia (SVT) = 51%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 30% and 30% combine to 51%, not 60%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.

Evidence for a Supraventricular Tachycardia (SVT) Secondary Claim
- •ECG tracings confirming supraventricular tachycardia, which both rating tiers require by name.
- •Records of each treatment intervention over the past year — intravenous pharmacologic adjustment, cardioversion, or ablation — since the annual count sets the tier.
- •A medication list identifying any oral medication used continuously to control the rhythm.
- •Cardiology notes identifying which supraventricular rhythm is present, such as atrial fibrillation or atrial flutter, both of which the schedule lists among its examples.
Common questions about Supraventricular Tachycardia (SVT) secondary to Hyperthyroid Heart Disease
- Can Supraventricular Tachycardia (SVT) be service-connected as secondary to Hyperthyroid Heart Disease?
- Yes. Under 38 CFR § 3.310, a condition that is caused or aggravated by an already service-connected disability can be granted secondary service connection. Thyroid hormone excess You'll need a current Supraventricular Tachycardia (SVT) diagnosis and a medical nexus opinion linking it to your service-connected Hyperthy…
- What VA rating can I get for Supraventricular Tachycardia (SVT) as a secondary condition?
- Supraventricular Tachycardia (SVT) is rated under VASRD diagnostic code 7010 using the same criteria whether it's a direct or secondary claim: possible ratings are 30%, 10%. The rating depends on the severity of Supraventricular Tachycardia (SVT) itself, not on the severity of Hyperthyroid Heart Disease.
- How does a secondary Supraventricular Tachycardia (SVT) claim affect my combined VA rating?
- The VA doesn't add ratings together. Using the official combined-ratings formula (38 CFR 4.25): a 30% rating for Hyperthyroid Heart Disease combined with a 30% rating for Supraventricular Tachycardia (SVT) (example figures) produces a combined rating of 51%, not 60%. Approving Supraventricular Tachycardia (SVT) as sec…
- What evidence do I need to service-connect Supraventricular Tachycardia (SVT) as secondary to Hyperthyroid Heart Disease?
- Strong evidence for the underlying Supraventricular Tachycardia (SVT) diagnosis includes: ECG tracings confirming supraventricular tachycardia, which both rating tiers require by name.; Records of each treatment intervention over the past year — intravenous pharmacologic adjustment, cardioversion, or ablation — since…
