Supraventricular Tachycardia (SVT) Secondary to Hyperthyroidism
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 Hyperthyroidism.
Why Supraventricular Tachycardia (SVT) Is Linked to Hyperthyroidism
Thyroid hormones affect heart rhythm
Primary condition · VASRD 7900
Hyperthyroidism
Hyperthyroidism is an overactive thyroid producing excess hormone, which speeds up metabolism and can cause rapid heartbeat, tremor, anxiety, heat intolerance and weight loss. Graves' disease is the most common cause and is rated under the same code.
Secondary condition · VASRD 7010
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 Hyperthyroidism — severity of Supraventricular Tachycardia (SVT) itself determines the percentage.
Example combined rating
30% Hyperthyroidism + 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 Hyperthyroidism
- Can Supraventricular Tachycardia (SVT) be service-connected as secondary to Hyperthyroidism?
- 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 hormones affect heart rhythm You'll need a current Supraventricular Tachycardia (SVT) diagnosis and a medical nexus opinion linking it to your service-conn…
- 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 Hyperthyroidism.
- 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 Hyperthyroidism combined with a 30% rating for Supraventricular Tachycardia (SVT) (example figures) produces a combined rating of 51%, not 60%. Approving Supraventricular Tachycardia (SVT) as secondary stil…
- What evidence do I need to service-connect Supraventricular Tachycardia (SVT) as secondary to Hyperthyroidism?
- 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…
