Abstract

A triangulation method is developed to detect and classify cardiac rhythms. The method is based on using omnidirectional concentric ring electrodes which are sensitive to local activation. Following extensive computer simulations, concentric, planar ring electrodes were tested in vitro. Selectivity is due to spatial differentiation, which is useful to determine the moment of depolarization near the electrodes. The signature of a specific depolarization pattern is characterized by the delays in depolarization among the three sensors. The origin of the depolarization is not necessary for classifying the arrhythmia. The signature depends only on the activity in the region of the triangle.
