Document Type and Number:
WIPO Patent Application WO/2020/005027
Kind Code:
A1
Abstract:
The present invention relates to an electrocardiogram measurement system using a wearable device, comprising a photoplethysmograph, and an electrocardiograph provided in a wearable device or an electrocardiograph which can be separated from the wearable device and carried, wherein the photoplethysmograph comprises a photoplethysmogram measurement circuit comprising an LED and a photodiode, an AD converter connected to an output terminal of the photoplethysmogram measurement circuit, for converting an analog signal to a digital signal, a wireless communication means for transmitting and receiving data, and a microcontroller for measuring photoplethysmogram, the microcontroller extracts photoplethysmogram parameters by analyzing the measured photoplethysmogram, determines generation of an alarm by using the extracted photoplethysmogram parameters, and generates the alarm on the basis of the determination result, and the electrocardiograph comprises three dry electrocardiogram measurement electrodes and two amplifiers for amplifying two electrocardiogram signals induced for two electrocardiogram electrodes out of the three electrocardiogram electrodes.
