Overview
There are no specific ECG findings associated with euthyroid sick syndrome. However, euthyroid sick syndrome leads to hypothyroidism. The decrease in the levels of thyroid hormones causes decreased activity of the sympathetic nervous system. There can also be deposition of myxoedematous material within the myocardium. ECG in hypothyroidism will present with QT prolongation, first degree AV block, interventricular conduction delay. Severe cases of hypothyroidism will have bradycardia and low QRS voltage.
Electrocardiogram
There are no ECG findings associated with euthyroid sick syndrome.
