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]
