The ECG Card is a 1-channel electrocardiograph monitor that detects arrhythmias and abnormal heartbeats. The body of the product is made of a flexible polymer and resembles a plastic credit card. Heart rate parameter measurements are taken by simultaneously pressing the card body with fingers of both hands. The sensors convert electrical signals into digital format. The data is transmitted to the user's mobile device and is analyzed using special algorithms. When pathological abnormalities are detected, alert signals are generated, and the result of the analysis is saved in cloud storage.
