Digital Simulating A Wave Shape Of Current Impulse Appearing On The Heart During Defibrillation
Dieter Lung, I. Basic · 2005
SUMMARY In this work. defibrillation of the heart has been analysed by impedance model of human body. The process of defibrillation was simulated on a personal computer and it was obtained a wave shape of electric current i mpul se appear i ng on the heart during def i br i 11 ati on. The analysis was done in 2 different positions of def i bri 11 ator electrodes. the ti me analysis of defibrillator impulses on other parts of the body shows the existence of current and voltage in the surroundings of heart. so we have to be very careful during defibrillation. This article points to an urgent need for the reduction of transient r esistance between skin and defibrillrtor electrodes up to lowest possible limit because of joule lossrs appearing here. The time analysis of impulses shows that we have to take in considerable influence on the wave shape of impulses and on voltage appearing on el ect r odes
