Obvi-ously also conditions of heart-block, of auricular fibrillation, or of auric-ular flutter will be immediately revealed by the electrocardiogram. Theinterpretation of abnormalities in the contour of the ventricular portionof the curve is, however, not so easy a matter, and should never beundertaken unless curves from the three leads have been secured, for itAvill
