An ingenious necklace which detects abnormal heart rhythm will be showcased for the first time on EHRA Essentials 4 You, a scientific platform of the European Society of Cardiology (ESC).

One of the major causes of stroke is unrecognised and untreated atrial fibrillation. Approximately 25% of all strokes are caused by atrial fibrillation. While it is the most common heart rhythm disturbance, atrial fibrillation is often symptomless and intermittent, making its detection and diagnosis challenging. Innovative methods for detection are therefore needed.

This study examined the diagnostic accuracy of an ECG worn around the neck . A single-lead ECG is embedded into the pendant. To measure their heart rhythm, users start an application on their smartphone then place the necklace pendant between the palms of their hands or between the palm and the chest for 30 seconds. Data are automatically sent to a cloud service and analysed for atrial fibrillation using artificial intelligence (AI). Within a few seconds, the smartphone application displays the results of the analysis. An ECG report is also generated for physicians to confirm the diagnosis.

The study enrolled 145 adults who used the necklace to measure their own heart rhythm. Participants simultaneously underwent a three-lead ECG recording as a ‘gold standard’ comparison.

Two cardiologists analysed all ECG readings without knowing the initial rhythm. Automated AI analysis of the necklace ECG was also performed. The necklace produced ECG recordings with excellent quality to detect and diagnose atrial fibrillation. Atrial fibrillation diagnoses made by standard ECG measurement were also picked up by the necklace device with high accuracy – both the automated AI analysis and interpretation of the ECG report by a cardiologist.
