N2 - Utilizing a mathematical model of the inhomogeneous torso, the effect of variations in the size of the heart on the amplitude of the surface potential is studied. The results show that the magnitude of the potential is increased with an increase in heart volume. It is shown that in cases of congestive heart failure, low potentials may result in spite of the cardiomegaly. This can be explained by the increased lung conductivity due to edema.
