Summary

This study tests whether giving magnesium through an IV can prevent new-onset atrial fibrillation (a type of irregular heartbeat) in critically ill patients in the intensive care unit. Researchers will enroll 200 adults and randomly assign them to receive either magnesium or a placebo. The main goal is to see if the study procedures are practical, not yet to prove the treatment works.

Active substance: Magnesium sulfate
What this could lead to: If it works, this could point toward a simple, low-cost way to prevent a common heart complication in ICU patients.
What could go wrong: This is a small pilot study focused on feasibility, not effectiveness. It may not show a clear benefit, and results may not apply to all ICU patients.
