In the field of medicine and wearable health devices, the need to monitoring cardiac activity continuously represents a challenge. Due to the random nature of many pathologies affecting the cardiac system, it is often necessary to continuously monitor cardiac activity. This means that portable ECG devices have to cope with movement noise, which is normally not present during an ambulatory measurement.

The aim of this study is to present a 12-lead ECG portable system based on TI ADS1298 and LSM6DSV16X from STMicroelectronics. The proposed device is capable of real-time ECG acquisition, managing to solve the problem of movement noise. A threshold mechanism was therefore implemented to allow the acquisition of the ECG signal based on the signal read by the accelerometer.

A threshold mechanism was therefore implemented to allow the acquisition of the ECG signal based on the signal read by the accelerometer. As a result, patients are able to carry out their daily activities while remaining continuously monitored.

The entire system has been extensively tested, and this article demonstrates its function. It was also demonstrated that the proposed layout does not degrade the performance recorded by the chip used.

We are currently developing a wearable board characterized by reduced weight, better portability, wireless connectivity, and integration of bioimpedance sensors.
