Which electrocardiogram change is commonly associated with hypocalcemia?
Correct answer: B. Prolonged QT interval
- A. Shortened QT interval
- B. Prolonged QT interval
- C. Peaked T waves
- D. Absent P waves only
Explanation
Low serum calcium prolongs ventricular repolarisation and may produce a prolonged QT interval. Peaked T waves are classically associated with hyperkalemia, while a shortened QT interval is more consistent with hypercalcemia.
