Overview
There are no CT scan findings associated with hyperparathyroidism. However, a CT scan may be helpful in the diagnosis of cardiac complications of hyperparathyroidism.
Electrocardiogram
There are no CT scan findings associated with hyperparathyroidism. However, a CT scan 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 amplitudein 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.
