Abstract
Displacement of the horizontal level of chest electrodes produced larger changes in data recorded with Frank than with axial leads, but anteroposterior displacement of lateral chest electrodes did not result in consistent differences between the lead systems. Variability of data recorded from normal subjects with Frank and axial leads was very similar, so this study did not provide a basis for a selection between these lead systems. Data recorded with Frank leads revealed smaller magnitude of QRS and T variables and a more superior location of mid and maximal QRS vectors in older normal subjects than in young subjects, while a shift in azimuth of mid and maximal QRS vectors was related to body build.
