A Prospective Observational Study in Adult Medical Intensive Care Unit Patients with Drug-Induced QTc with Correlation of Serum Potassium, Magnesium Level of Clinical Outcome.

Background: Drug-induced QTc prolongation is a significant concern in critically ill patients, increasing the risk of life-threatening arrhythmias. This prospective observational study evaluates the association between QTc prolongation, serum potassium and magnesium levels, and clinical outcomes in adult medical intensive care unit (ICU) patients.

Methodology: The study included 116 adult ICU patients prescribed QTc-prolonging drugs, excluding those with atrial fibrillation, pacemakers, or early transfers.
