Evaluation of the accuracy of measuring leads for mapping the electric field of the heart

  • Published:
Measurement Techniques Aims and scope

Abstract

A lead system is described for measuring the electric field of the heart on the surface of the thorax. It is sufficiently accurate and convenient for electrocardiographic mapping under clinical conditions. A method of quasimultipole approximation of the potential is presented. This is based on the expansion of the latter in a series of spatial spherical functions, and provides accurate interpolation, with simultaneous filtering and removing the uninformative highfrequency spatial components of the measured signals.
