Testing a device feature to reduce interference in heart monitoring

Official title: The Efficacy of the Smart Pass Filter to Reduce the Risk for Inappropriate Subcutaneous Implantable Cardioverter-defibrillator Shocks From Myopotential Interference

Run by Medical University of South Carolina · NCT05766943 · Data updated 2026-11-12

This study is testing a new feature in heart monitoring devices to see if it can better tell the difference between muscle movements and heart signals during arm exercises for people who already have an implanted device.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who have an EMBLEM S-ICD device implanted.

Probably not a fit

Patients who are hemodynamically unstable or unable to perform the required exercises due to orthopedic issues or cognitive impairment may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study involves participants who already have a subcutaneous ICD device implanted and are attending a routine follow-up appointment. The goal is to evaluate a feature that can distinguish between muscle movements and irregular heart signals during simple arm exercises. Participants will be randomly assigned to have this feature either activated or deactivated during the exercises, with data collected in both scenarios. The study requires only one visit for participation.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of heart monitoring in patients with S-ICD devices.

How similar studies have gone: While this approach is innovative, similar studies have not been widely reported, indicating this may be a novel investigation.
