High Frequency of Early Repolarization and Brugada-Type Electrocardiograms in Hypercalcemia.

ABSTRACT:

Background

J wave, or early repolarization has recently been associated with an increased risk of lethal arrhythmia and sudden death, both in idiopathic ventricular fibrillation and in the general population. Hypercalcemia is one of the causes of J point and ST segment elevation, but the relationship has not been well studied. The aim of this study was to examine the effects of hypercalcemia on J point elevation.

Methods

Electrocardiographic findings were compared in 89 patients with hypercalcemia and 267 age- and sex-matched healthy controls with normocalcemia. The association of J point elevation with arrhythmia events in patients with hypercalcemia was also studied.

Results

The PR interval and the QRS duration were longer in patients with hypercalcemia than in norm
