Study of The Electrical Properties of Pacemaker Leads

Abstract:   Abstract The purpose of this thesis is to examine the electrical properties of pacemaker leads by measurements and theoretical analysis. If time allows, recommendations on how to construct a simple circuit model to explain the phenomenon will be given based on the electrical properties obtained from measurements performed during the work of this thesis. Additional information on pacemaker lead heating during impact of magnet in X-ray (MRI) will be presented if time allows. Significant electrical properties of pacemaker leads are compiled in this thesis.   ANALYSIS OF CIRCUIT MODEL The purpose of this model is to create an equivalent electronic circuit model that describes a pacemaker lead electrical property. The model is divided into three different sections: proximal part, the homogeneous coil part and the distal end.  The model will include series inductance, parallel capacitance, series resistance, lossless admittance and winding capacitance between each loop for the homogeneous coil part, additionally the impedance of the proximal and distal part will be included.
