Novel necklace detects abnormal heart rhythm

May 05, 2020

Sophia Antipolis - 5 May 2020: 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).

"The wearable necklace-ECG (electrocardiogram) provides a new and easy method for detecting an abnormal heart rhythm called atrial fibrillation, which is a fast-growing public health problem," said study author Mr. Elmeri Santala, a medical student at the University of Eastern Finland.

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 (see photo). 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 (i.e. they were blinded to the 3-lead ECG recordings and initial 12-lead ECG). 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.

Mr. Santala said: "The necklace ECG is simple to use and allows repetitive self-monitoring of heart rhythm, thereby improving the likelihood of detecting atrial fibrillation. The ESC recommends screening for atrial fibrillation in people over 65 years of age and in those at high risk of stroke;1 automated analysis by the necklace ECG is well suited for this purpose. Diagnosis of atrial fibrillation should always be confirmed by a physician using the ECG report."

What If?
There's plenty of speculation about what Donald Trump might do in the wake of the election. Would he dispute the results if he loses? Would he simply refuse to leave office, or even try to use the military to maintain control? Last summer, Rosa Brooks got together a team of experts and political operatives from both sides of the aisle to ask a slightly different question. Rather than arguing about whether he'd do those things, they dug into what exactly would happen if he did. Part war game part choose your own adventure, Rosa's Transition Integrity Project doesn't give us any predictions, and it isn't a referendum on Trump. Instead, it's a deeply illuminating stress test on our laws, our institutions, and on the commitment to democracy written into the constitution. This episode was reported by Bethel Habte, with help from Tracie Hunte, and produced by Bethel Habte. Jeremy Bloom provided original music.
