NCT ID NCT01420393
First seen May 16, 2026 · Last updated May 16, 2026
Summary
This study looked at 411 people with both heart failure and atrial fibrillation (a fast, irregular heartbeat). It compared two approaches: using a catheter to burn small areas in the heart to restore normal rhythm, versus simply controlling the heart rate with medication. The goal was to see which method better reduces deaths and hospital stays for heart problems.
