Secondary Condition Claim · VASRD 7010
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 arrhythmias when it develops after Hyperthyroidism.
Thyroid hormones affect heart rhythm
Primary condition · VASRD 7912
Hyperthyroidism
Overactive thyroid causing fast heartbeat, anxiety, and weight loss.
Secondary condition · VASRD 7010
Supraventricular arrhythmias
Irregular heart rhythms originating in the upper chambers of the heart.
The VA rates Supraventricular arrhythmias the same way whether it's claimed directly or as secondary to Hyperthyroidism — severity of Supraventricular arrhythmias itself determines the percentage.
Example combined rating
30% Hyperthyroidism + 30% Supraventricular arrhythmias = 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.
