Effects of Potassium Currents upon Action Potential of Cardiac Cells Exposed to External Electric fields
Effects of Potassium Currents upon Action Potential of Cardiac Cells Exposed to External Electric fields
摘要
Abstract
Previous studies show that exposure to high-voltage electric fields would influence the electro cardiogram both in experimental animate and human beings. The effects of the external electric fields upon action potential of cardiac cells are studied in this paper based on the dynamical model, LR91. Fourth order Runger-Kuta is used to analyze the change of potassium ion channels exposed to external electric fields in detail. Results indicate that external electric fields could influence the current of potassium ion by adding an induced component voltage on membrane. This phenomenon might be one of the reasons of heart rate anomaly under the high-voltage electric fields.关键词
