The Mechanism and Graphic Registration of the Heart Beat.

·1925·JAMA: The Journal of the American Medical Association

Abstract

This is really a new edition and not simply a reprint of the previous edition, with slight changes. We may quote from the publisher's announcement the following facts that are borne out by an examination of the volume: Three of the original chapters have been omitted and eight new chapters have been added. Much new material has been incorporated into other chapters. Much of the old text has been compressed. Altogether there are sixty more pages than in the former edition. The book has been brought down to date. There is full consideration of circus movement, the action of quinidin, the origin of extrasystolic disturbances, and the theory of heart block. We may add that the commanding position occupied by Lewis as an authority on the heart, his gift of clear writing, and the excellent work of the publishers, make this a book that students of heart problems will be

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
