Overview
There are no specific ECG findings associated with Multiple endocrine neoplasia type-1. However, hypercalcemia secondary to hyperparathyroidism.
Electrocardiogram
There are no ECG findings associated with MEN-1. 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.
