Abstract
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 incases 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.
摘要
利用非均匀躯干的数学模型，研究了心脏大小变化对体表电位幅度的影响。结果表明，在充血性心力衰竭的情况下，尽管心脏肿大，电位仍可能较低。这可以用因水肿导致的肺电导率增加来解释。
