The feasibility of using the fast Hartley transform (FHT) algorithm for ECG data compression was studied. The technique is simple and requires the implementation of forward and inverse FHT. Using the percent is difference as a measure of the utility of the reconstructed signals, the limit to which an ECG signal could be compressed and still yield an acceptable reconstructed wave form was determined. Results of compression of ECG data obtained from normal and abnormal subjects are presented.
