Abstract

We report the case of a 77-year-old woman who developed complete atrioventricular (AV) block during an episode of thiazide-induced hyponatremia. She was taking hydrochlorothiazide to treat essential hypertension; she had no definite organic disease of the heart or lungs. Generally, the serum sodium concentration does not have a marked effect on cardiac conduction. However, we experienced a case of complete AV block associated with hyponatremia. This was treated successfully by correcting the electrolyte imbalance. Complete AV block associated with hyponatremia is very rare. To our knowledge, this is the first reported case in Korea.
