Abstract:
Introduction Cardiac pacing requires attachment of pacing leads to the heart. Due to cyclic cardiac contraction the tissue and the leads deform. As a result, heart wall motion may affect proper functioning of the lead. Secondly, the contraction pattern changes due to a different pacing site. Assessment of the effects of changing the pacing site may be facilitated by prediction of the motion of the wall of the left ventricle as a function of time during the cardiac cycle. Objective A finite element model of the complete heart will be developed to simulate the electromechanical events during the cardiac cycle. Fig. 1 Left: Long axis cross-section of the human heart. LA = left atrium, RA = right atrium, LV = left ventricle, RV = right ventricle. Right: Anisotropic fiber distribution in the LV model of Bovendeerd Stress, strain, pressures and volumes will be calculated in a normal working heart as well as during pacing at various site
