Abstract
A method has been developed for removing the P-wave from the electrocardiogram to facilitate the study of the electrical activity in the atrio-ventricular conduction system and in particular of the activity in the bundle of His. When the PQ-segment in the electrocardiogram of a subject at rest is subtracted from the PQ-segment of the same subject shortly after exercise stress, the resulting signal will, because of the changed PQ-time, be a distored P-wave. Reconstruction of the P-wave can then be accomplished with the help of a special algorithm after which the reconstructed P-wave can be subtracted from the e.c.g.
