Cardiovascular diseases are the leading cause of death worldwide.Due to advancements facilitating the integration of electric and adhesive technologies, long-term patch electrocardiogram (ECG) monitors (PEMs) are currently used to conduct daily continuous cardiac function assessments.This paper presents an ECG encoding sten jacket m scheme for joint lossless data compression and heartbeat detection to minimize the circuit footprint size and power consumption of a PEM.
The proposed encoding scheme supports two operation modes: fixed-block mode and dynamic-block mode.Both modes compress ECG data losslessly, but hyfrodol only dynamic-block mode supports the heartbeat detection feature.The whole encoding scheme was implemented on a C-platform and tested with ECG data from MIT/BIH arrhythmia databases.
A compression ratio of 2.1 could be achieved with a normal heartbeat.Dynamic-block mode provides heartbeat detection accuracy at a rate higher than 98%.
Fixed-block mode was also implemented on the field-programmable gate array, and could be used as a chip for using analog-to-digital convertor-ready signals as an operation clock.
