Fig. 4From: Electrocardiogram: his bundle potentials can be recorded noninvasively beat by beat on surface electrocardiogramComparative study of PAs, AHs and HVs interval recorded on “New electrocardiogram” and PA, AH and HV interval recorded on His bundle electrogram in one subject. a shows the new electrocardiogram (upper trace) and conventional electrocardiogram (lower trace). b shows the His bundle electrogram. The PAs, AHs and HVs intervals on new electrocardiogram are consistent with the intra-atrial measurement (PA, AH and HV interval). Figure is representative of one subject with similar resultsBack to article page
