Body surface isochrone maps of peak R in normal adolescent girls.
The aim of our study was to evaluate the adequacy of a new mapping device for obtaining a reliable set of normal maps characteristic for this approach. We studied body surface isochrone maps of peak R in four healthy adolescent girls using the mapping system CARDIAG 128.1 with 80 unipolar leads placed in a regular grid. The constructed maps were compared with published data using 10 criteria. None of the maps obtained could be regarded as normal. After evaluating the reasons for the "abnormality", we assume that they could be caused mostly by the processing of signals. This fact can be eliminated by improving the existing software.
