Abstract :
Exercise ECG (XECG) testing is one of the clinical routine examinations which produces a large amount of data if full-disclosure records aree to be provided. We describe a system for XECG analysis which takes advantage of the data compression procedures and the data format of the SCP-ECG (Standard Communication Protocol for computer-assisted Electrocardiography) protocol. Processing the XECG data in consecutive 10-s data sections resulted in six SCP blocks per minute. Over a test set of 20 XECGs with various test durations, a median compression ratio of 11.1 has been achieved. We have also investigated the influence of noise on the compression ratio. 50 μV RMS may reduce the compression ratio from ~17 to ~8
