To deal with shortcomings of current ECG monitoring system
design an ECG monitoring system based on wearable device. This system is mainly composed of an AD8232 biochip
ultra low power consumption Microcontroller MSP430FR5738 and a Micro-SD card. Introduce the specific designs of system software and hardware are introduced detailedly and a realtime heart rate extraction algorithm is proposed with dynamic double threshold value. By testing power consumption of this system and by verifying realtime heart rate algorithm
it is concluded that this system has many advantages of wearable devices
