3D PRINTED HOLTER ELECTROCARDIOGRAM (ECG)

This study was aimed to design a low cost and ergonomic Holter Electrocardiogram (ECG) that allows remote monitoring of patients who need to be followed up by a doctor with the Covid19 pandemic period, sends SMS to the doctor or relatives of the patient in risky situations, and recordes and stores patient data. In this study, a 55x84 mm PCB electronic circuit was designed. Signals received from the patient through the electrodes are detected with the help of the AD8232 ECG sensor and transmitted to the ESP32, which is the processor of the system, and an SMS is sent to the doctor or relatives of the patient in risky situations, thanks to the UG96 GSM module. In addition, thanks to the wifi feature of the UG96 GSM module, the ECG data recorded in risky situations is stored in the ubidots. The doctor can access the patient's ECG data via ubidots.
