Abstract

  • 1.

    (1) A review is presented of the contributions to the understanding of the normal and abnormal spread of the cardiac impulse, which have been revealed by the study of fusion beats (transtitional complexes, combination complexes) in the electrocardiogram.

  • 2.

    (2) A classification of fusion beats is given, based on two criteria: origin of the fusing impulses and site of fusion.

  • 3.

    (3) The various mechanisms reflected in the electrocardiogram exhibiting fusion beats are discussed and illustrated.

  • 4.

    (4) A case of Wolff-Parkinson-White syndrome with auricular fibrillation, showing complexes with a transitional contour (fusion beats), is presented as new evidence to demonstrate the functioning of both the normal, and an accessory, pathway in the Wolff-Parkinson-White syndrome.
