Overview
Electrocardiogram
Findings on ECG are due to hypercalcemia and includes:[1]
- 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.
- A shortening of the QTc interval
- The decrease is at the expense of the ST segment which becomes shortened or absent.
- This is true for Ca of up to 16 meq/li, after this QTc prolongation occurs
