In the Statement of Principles for atrial fibrillation the RMA has defined hyperthyroidism as “thyrotoxicosis or subclinical hyperthyroidism”.
Subclinical hyperthyroidism is simply an excess of thyroid hormones without clinical manifestations, ie where symptoms and signs are not apparent or detectable by clinical examination.
Note: While goitre, covered by a SOP, is a clinical manifestation of hyperthyroidism, goitre is not a cause of atrial fibrillation. Therefore, the goitre SOP should not be used for propagation purposes when considering the hyperthyroidism factor in atrial fibrillation.
34729 there is some evidence that hyperthyroidism may be a factor in the development of the condition under consideration.
28996 the veteran has suffered from hyperthyroidism at some time.
34731 the veteran suffered from hyperthyroidism at the time of the clinical onset of atrial fibrillation.<hotword
34732 the veteran has established the causal connection between the hyperthyroidism at the time of onset of atrial fibrillation and VEA service for the clinical onset of atrial fibrillation.
34733 the veteran has established the causal connection between the hyperthyroidism at the time of onset of atrial fibrillation and operational service for the clinical onset of atrial fibrillation.
or
34734 the veteran has established the causal connection between the hyperthyroidism at the time of onset of atrial fibrillation and eligible service for the clinical onset of atrial fibrillation.
34735 the hyperthyroidism is causally related to operational service.
34736 the hyperthyroidism is causally related to eligible service.
