Overview
The ECG findings associated familial hypocalciuric hypercalcemia are due to cardiac complications of hypercalcemia.
Electrocardiogram
There are no ECG findings associated with familial hypocalciuric hypercalcemia. However, an ECG may be helpful in the diagnosis of cardiac complications of hypercalcemia. 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 the 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.
