RT Journal T1 AN atlas of electrocardiography. JF Archives of Internal Medicine JO Archives of Internal Medicine YR 1949 FD October 1 VO 84 IS 4 SP 666 OP 666 DO 10.1001/archinte.1949.00230040145021 UL http://dx.doi.org/10.1001/archinte.1949.00230040145021 AB This atlas is not particularly different from others available. It consists of photographs of electrocardiograms presented on one page with clinical and other related data and the electrocardiographic data on the opposite page. This conventional procedure of making the tracing and the discussion available to the reader simultaneously is obviously a good one. Some interpretations are documented with postmortem findings. Unfortunately, the chest leads presented in most of the cases consist of CF and CR leads rather than unipolar leads. If these leads are to be presented the unipolar leads should not be excluded. As the authors state, the atlas is not intended for beginners; it may be of value to others.
