Thoracic current pathways for different size position external defibrillation electrodes based on a 3D model

Abstract

A 3D finite difference model was developed base on MR images in order to determine an improved electrode size and position for external defibrillation. With 10×10 cm electrodes in the standard position on the anterior surface of the thoracic, 23% of the current passed through the heart. Moving each electrode laterally 3.3 cm reduced the current passing through the heart to 17% but improved an index based on the uniformity of the currently passing the myocardium by nearly a factor of two. About 42% of the total current flowed through the skeletal muscle independent of electrode size and position. It appears an improved electrode size and position can be developed but its effect on the output level settings used with commercial defibrillators needs to be carefully considered because of load impedance changes.
