The fourth complex is always premature, most prob-ably a nodal extrasystole, and the whole represents a recurring dislocation of the pace-maker, the origin of each of the 4 stimuli being different. Congenital Heart —In most cases of congenital heart disease,the electrocardiogram will merely show the result that the lesion hasproduced in the muscle balance [, there is usually a right ventricularpreponderance) with exaggerated amphtude of all deflections. Indextrocardia, however, there is so great a change in the position of theheart in relation to the 3 customary leads that the form o
