There are 2 ways to measure ECG, including rapid measurement by electrodes integrated and long-term measurement with lead wires:

1. Integrated electrode measurement: fast and easy ECG measurement via the integrated electrodes can be done by placing the electrodes in the hand, leg, and chest, respectively.

2. Measurement by external wires:
ECG signal through external wires is more stable than the manual. ECG measurement by external wires can be made by placing electrodes in the limbs or chest, respectively.
