Heart rhythm secrets in thick heart muscle disease revealed
NCT ID NCT04112290
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This study looks at heart rhythm problems in people with hypertrophic cardiomyopathy, a condition where the heart muscle is thicker than normal. Researchers want to see how often new rhythm issues like atrial fibrillation happen, and whether sleep apnea plays a role. About 260 adults are being followed over time to gather this information.
