Abstract

Spatially differentiating rectangular-body-surface electrodes have been designed and fabricated on the basis of computer simulations of the potential generated on the electrodes by propagating dipolar wavefronts. The electrodes were tested on human subjects for their ability to detect atrial and reject ventricular depolarizations. This technique, using 2.2 × 4.4 cm nested electrodes, has yielded detectable atrial signals with body surface electrodes, however, the ventricular signals remained substantial. This result suggests a potentially important application in ambulatory arrhythmia monitoring.
