Overview

Most common finding on ECG due to hypercalcemia is short QT interval.

Electrocardiogram

Findings on ECG are due to hypercalcemia and includes:[1][2]

  • QT interval - Short QT interval is seen in pateints if hypercalcemia.
  • ST segment - ST segment is short in patients with hypercalcemia when compared to normocalcemic patients. This represents a decrease in systolic interval.
  • QRS complex - QRS complex has an increased amplitude in patients with hypercalcemia when compared to normocalcemic patients. This represents an increase in ventricular muscle mass.
  • T wave - T wave is prolonged in patients with hypercalcemia when compared to normocalcemic patients.

Note: Severe hypercalcacemia may mimic acute myocardial infarction.[3]
