Summary

This study tested a wearable heart monitor called Cardea SOLO against a standard 12-lead EKG to see if it could better detect paroxysmal atrial fibrillation (a temporary irregular heartbeat) in people who had a stroke of unknown cause and have an enlarged heart. 257 participants wore the device or had standard EKGs. The goal was to see if the device catches more cases of atrial fibrillation lasting over 30 seconds, which could help guide treatment to prevent another stroke.

What this could mean

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

Active substance: Cardea SOLO (a wearable heart monitor device)
What this could lead to: If successful, this device could help doctors find hidden atrial fibrillation in stroke survivors more easily, potentially preventing future strokes.
What could go wrong: This is a completed study with 257 participants, but the device may not detect all cases of atrial fibrillation, and results may not apply to all stroke patients.
