Abstract

This work presents the development of an automated modeling system to obtain a piece-wise linear electrical model of bradycardia pacing leads. In vivo studies were performed on a canine model under acute conditions, and a computer algorithm was used to determine and verify the model parameters. This iterative algorithm provided a first order electrical model of a type 4058 atrial pacing lead, where the mean point-to-point discrepancy in the time domain was around two percent. This study showed that a piece-wise linear equivalent circuit for the impedance seen by a pacemaker can be determined automatically from acutely collected data
