Isopotential body surface maps and their relationship to atrial potentials in the dog.
The origin of body surface P waves was evaluated in the intact dog by recording body surface isopotential maps and atrial epicardial potential maps. P waves were recorded from 150 points on the body surface, and 80 atrial unipolar electrograms were recorded by means of permanently implanted atrial electrodes during normal sinus rhythm and during atrial pacing. When the atrial pacing sites were ...
متن کاملInterpretation of Isopotential Surface Maps in Patients with Ostium Primum and Secundum Atrial Defects By RIcHARD
purpose was to interpret the isopotential surface maps in terms of the position of intracardiac electrical wave fronts. Body surface activity throughout QRS demonstrated three major intervals: developing, transitional, and declining potentials. Patients with both types of atrial septal defects demonstrated complex distributions (multiple maxima) during the transitional interval which were not e...

متن کاملExperimental evidence for regional cardiac influence in body surface isopotential maps of dogs.
Isopotential mpas based on 192-200 body surface electrocardiograms were obtained for 20 dogs during multiple patterns of ventricular activation. The purposes of the study were to determine whether the cardiac location of events responsible for surface potentials had a recognizable influence on surface potential patterns and to examine the influence of electrical events occurring simultaneously ...
