First seen Jun 24, 2026 · Last updated Jun 30, 2026 · Updated 3 times
Summary
This study tests whether giving magnesium along with the standard drug metoprolol can quickly lower a dangerously fast heart rate in people with atrial fibrillation or atrial flutter. About 196 adults in the emergency room will receive either magnesium or a placebo, plus metoprolol. The goal is to see if the combination works better than metoprolol alone.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Magnesium sulfate (given intravenously) plus metoprolol
- What this could lead to
- If it works, this could provide a simple, low-cost way to quickly lower dangerously fast heart rates in people with atrial fibrillation in the emergency room.
- What could go wrong
- This is a small, early-phase trial (196 participants) testing a common mineral supplement. The benefit may be modest, and there are risks like low blood pressure or slow heart rate. Results may not apply to all patients.
