Syndrome of inappropriate antidiuretic hormone electrocardiogram
Introduction
Overview
Overview
Electrocardiogram (EKG) may be helpful in the diagnosis of SIADH. Findings on an EKG suggestive of SIADH are like classic Brugada like pattern, include downward coving of ST-segment and T-wave inversion in the anterior precordial leads. The EKG changes will be normalized after the sodium levels were corrected.
