The authors examine the distribution of the transmembrane potential in the periodic strand of cardiac muscle established by configurations of sources similar to those arising during extracellular stimulation and defibrillation, during intracellular stimulation, and during propagation of action potential. The closed-form solution indicates that during extracellular stimulation with large current and during defibrillation, the period component of the transmembrane potential is very important. The closed-form solution obtained from asymptotic analysis revealed that the potential field reflects the periodicity of cardiac muscle, but in very different ways that depend on the location of the sources. The results derived were used to compare the mechanism of depolarization during extracellular stimulation and defibrillation, during intracellular stimulation, and during propagation.Keywords:
