Abstract
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. The two ECG signals are converted into two digital lead signals and wirelessly transmitted to the smartphone. The smartphone generates four additional derived lead signals and displays a six-lead ECG waveform based on the two received signals.
