Heart shock therapy put to the test: Placebo-Controlled trial reveals true impact on daily life
NCT ID NCT05136131
First seen Jun 25, 2026 · Last updated Jul 01, 2026 · Updated 2 times
Summary
This study compares electrical cardioversion—a procedure that delivers a shock to restore normal heart rhythm—to a sham version where no shock is given. Researchers want to see if the real procedure truly improves quality of life in people with persistent atrial fibrillation, a common heart rhythm disorder. One hundred participants will be randomly assigned to receive either the real shock or the sham, and their quality of life will be measured using a standard survey.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
electrical cardioversion
What this could lead to
If it works, this could confirm that restoring normal heart rhythm with cardioversion meaningfully improves quality of life for people with persistent atrial fibrillation.
What could go wrong
This is a small, early-stage trial with only 100 participants. The sham control may reveal that the perceived benefit is partly due to a placebo effect, and results may not apply to all AF patients.
