摘要

An electrocardiogram (ECG) measurement method with reduced power consumption for displaying a six-lead ECG waveform using a portable apparatus and a smartphone is disclosed. The apparatus includes three electrodes configured to contact both hands and a left leg of a user, two contact detectors configured to detect a contact status of the user, and a microcontroller. Upon detecting simultaneous contact on all three electrodes, the microcontroller transitions from a low-power mode to an active mode, activating two amplifiers and a constant voltage generator to acquire two ECG signals.…
