What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests how well a new device, Withings SCT02, can detect atrial fibrillation, a type of irregular heartbeat. Participants will use the device to record their heart's electrical activity, and researchers will compare these results with those from standard devices. The trial includes groups for people with atrial fibrillation, normal heart rhythms, and other irregular heartbeats. It suits individuals who frequently experience irregular heartbeats and do not have implanted electrical devices, such as pacemakers. As an unphased trial, this study allows participants to contribute to innovative research that may enhance heart health monitoring.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the study staff for guidance.

What prior data suggests that this device is safe for atrial fibrillation detection?

Research shows that the Withings SCT02 device, which uses an app to check for irregular heartbeats, is both reliable and safe. Studies on similar devices, such as the Withings ECG App, have found they can detect heart problems without causing harm. While specific side effect information for the SCT02 is unavailable, similar devices have been well-tolerated. This study aims to confirm these findings, suggesting that the device is expected to be safe. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Withings SCT02 device because it offers a new way to detect atrial fibrillation (AFib) using simultaneous ECG recordings with both investigational and reference devices. Unlike traditional methods that often require in-clinic visits or cumbersome equipment, this device could potentially allow for more accessible and continuous heart monitoring, making it easier for patients to track their heart rhythms in real-time. This could lead to earlier detection and intervention for AFib, which is crucial for preventing complications like stroke. By providing a user-friendly and possibly more efficient way to monitor heart health, the Withings device stands out from existing treatments that generally focus on medication or invasive procedures.

What evidence suggests that the Withings SCT02 device is effective for detecting atrial fibrillation?

Research shows that the Withings SCT02 device, equipped with an ECG app, effectively detects atrial fibrillation (AF), a common heart rhythm issue. One study found that the device correctly identified 86% of actual AF cases, demonstrating its sensitivity. It also accurately recognized 94% of cases without AF, indicating its specificity. In this trial, participants will join different arms to test the device's effectiveness in detecting AF, normal sinus rhythm, and arrhythmias other than AF. These findings suggest that the device reliably identifies AF and distinguishes it from other heart rhythms, making it a promising tool for monitoring heart health, particularly for detecting AF. ^{2 3 4 6 7}

Published Research Related to This Trial

Wearable technology, particularly smartwatches using photoplethysmography (PPG), shows promise in effectively screening for asymptomatic atrial fibrillation (AF), which is crucial since AF can lead to strokes in individuals who may not even know they have it.

While smartwatches can increase the detection of AF cases compared to traditional methods, they should be viewed as a preliminary screening tool rather than a definitive diagnostic method, necessitating follow-up with healthcare professionals for confirmation and treatment.

Apple Watch, Wearables, and Heart Rhythm: where do we stand? Raja, JM., Elsakr, C., Roman, S., et al.[2020]

Mobile health devices that detect atrial fibrillation are becoming widely used and can identify more cases than traditional care, but there is ongoing debate about the appropriateness of screening, especially in younger populations.

Physicians need to be aware of the capabilities and limitations of these devices, as increased detection may lead to more referrals for genetic evaluation in younger patients with early-onset atrial fibrillation.
