Kardi Ai ECG telemetry monitoring for detecting heart rhythm problems

Clinical Safety and Efficacy Testing of a Medical Device Kardi Ai, an ECG Telemetry Monitoring System Using Artificial Intelligence to Evaluate ECGs Measured by Hardware Component (POLAR H10 Chest Strap)

Not applicable Interventional KARDI AI Technologies s.r.o. · NCT07018648

The Kardi Ai wearable ECG system will be tested to see if it can accurately detect irregular heart rhythms in adults with or suspected of having heart rhythm disorders.

What this trial studies

Participants are given the Kardi Ai system (Polar H10 chest strap plus mobile app) to record ECGs at home on at least five different days, totaling at least 10 hours of data with measurements typically done three times per week for two hours each. Recorded ECGs are uploaded to the Kardi Ai cloud and analyzed by the device's AI algorithm, with results compared to expert cardiologist interpretation as the reference standard. The study will report diagnostic test statistics (sensitivity, specificity, predictive values) across all targeted rhythm disorders and for each disorder separately, and will also rate ECG recording quality. Inclusion requires adults able to use a smartphone and the app; key exclusions include pregnancy and skin problems at the chest strap site.

Who should consider this trial

Good fit: Adults (18+) with confirmed or suspected heart rhythm disorders who can use a compatible smartphone and wear a chest-strap ECG sensor are the ideal candidates.

Not a fit: People who cannot operate a smartphone, have skin reactions at the chest strap site, are pregnant, or who need implantable monitoring rather than external ECGs are unlikely to benefit from this device.

Why it matters

Potential benefit: If successful, Kardi Ai could allow earlier, more convenient detection of atrial fibrillation and other arrhythmias from home, enabling faster clinical follow-up and treatment.

How similar studies have performed: Previous studies of wearable ECG devices and AI algorithms have shown promising accuracy for atrial fibrillation detection, though performance varies by device, recording quality, and rhythm type.
