Fig. 4From: Feasibility study of transfer function model on electrocardiogram change caused by acupunctureThree SAECGs and simulated results. a Three SAECGs; measured SAECG, simulated SAECG by individual, and generalized transfer function. b Example of 3 acupuncture SAECGs: a measured SAECG, a simulated SAECG by individual transfer function, and a simulated SAECG by generalized transfer function. ITF, individual transfer function; GTF, generalized transfer function; SAECG, signal-averaged electrocardiogram; BDA, before and during acupunctureBack to article page
