Overview
There are no ECG findings associated with hyperparathyroidism. However, an ECG may be helpful in the diagnosis of cardiac complications of hyperparathyroidism.
Electrocardiogram
There are no ECG findings associated with hyperparathyroidism. However, an ECG may be helpful in the diagnosis of cardiac complications of hyperparathyroidism. Findings on ECG are due to hypercalcemia and includes:[1]
- ST segment - ST segment is short in patients with hyperparathyroidism when compared to normocalcemic patients. This represents a decrease in systolic interval.
- QRS complex - QRS complex has an increased amplitude in patients with hyperparathyroidism when compared to normocalcemic patients. This represents an increase in ventricular muscle mass.
- T wave - T wave is prolonged in patients with hyperparathyroidism when compared to normocalcemic patients.
