The invention works like an electrocardiogram and was highly accurate in testing with patients, contributing to the diagnosis of heart disease.

Scientists at the University of Eastern Finland have developed a necklace that detects abnormal heart rhythm. It works like an electrocardiogram (ECG) and connects to a smartphone app to show the results.

The procedure is simple: first, patients start an application on their smartphone and place the necklace between their palms or between their palm and chest for 30 seconds. The data is automatically sent to a cloud service and analyzed by an artificial intelligence system. Within a few seconds, the application displays the analysis and sends a report to the doctors, who confirm the diagnosis.

“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 the study’s author, Elmeri Santala, in a statement. The disease can be dangerous because it has no symptoms, making diagnosis difficult. When detected, it is possible to avoid complications such as stroke, heart failure and heart attacks.

The study involved 145 adults who used the necklace to measure their own heart rhythm. The participants were simultaneously submitted to an ECG and two cardiologists analyzed all the readings without knowing the initial rhythm of each one. After the analyzes, the team found that the exam performs the correct reading and with high precision.

According to Santala, the test is recommended for people over 65 and for those at high risk of stroke. However, no matter how much the patient uses the collar to measure the heart rhythm, the diagnosis of atrial fibrillation must always be confirmed by a doctor.
