Summary

This study looks at whether keeping low- and intermediate-risk fainting patients in the hospital for 24 hours with a heart monitor is better than sending them home right away. About 640 adults will be randomly assigned to either stay or go home. The goal is to see if the longer monitoring catches more heart rhythm problems that could be dangerous.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: 24-hour heart monitor (Holter)
What this could lead to: If it works, this could show that 24-hour observation helps detect hidden heart rhythm problems in low-risk fainting patients, potentially improving care.
What could go wrong: This is an early-stage trial with 640 participants, so results may not apply to everyone. The benefit of extra monitoring might be small and not worth the hospital stay.
