Which ECG feature may be observed in severe cases of hyponatremia?

Understand the Problem

The question is asking which ECG feature is related to severe cases of hyponatremia. This involves understanding the effects of electrolyte imbalances on heart function as represented on an ECG.

More Information

Severe hyponatremia can cause changes in ECG readings, such as peaked T waves. These changes in T-wave morphology can revert back to normal once the hyponatremia is corrected.

Tips

A common mistake is confusing severity of hyponatremia with other electrolyte imbalances, leading to incorrect identification of ECG features.
