New filter may stop heart device from shocking you when you move
NCT ID NCT05766943
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at a feature in a heart device (subcutaneous ICD) that might tell the difference between muscle movement and dangerous heart rhythms. About 71 adults who already have the device will do simple arm exercises while the feature is turned on and off. The goal is to see if the filter reduces false signals that could lead to unnecessary shocks.
