| 内容記述 | An analysis of the relation between electrocardiogram (ECG) and intracellular action potential in heart cells was performed using two considerations, that is, with the extracellular action potential induced from the differentiated intracellular action potential (Inomata et al (2005)), and the size of the extracellular action potential dependent upon the number of synchronized cells. The following results were obtained : (1) The extracellular action potential from Ventricular muscles was larger than such potentials from other parts, and this potential from the Atrial muscles was secondary (1/5～1/10 potential from Ventricular muscles), but this potential from other parts (Atrioventricular node, Common bundle, Purkinje fibers etc.) was small, so this small potential disappeared from the record of ECG, then these two extracellular action potentials (Ventricular and Atrial muscles) were applied for an analysis of the ECG. (2) Similar patterns for the P wave and QRS complex in ECG was found in the course of the differentiated intracellular action potential in Atrial and Ventricular muscles (Fig.4,A'+V'). (3) The peak of the T wave usually showed positive (same direction for R wave), but sometimes it showed negative (Goldman, M.J. [Intermediate Heart Position]), the cause for this discrepancy was as follows : a) the relationship between electrode and heart position in the thorax. b) the existence of afterhyper-polarization (intracellular action potential) on Ventricular muscle fibres or absence of this afterhyper-polarization. c) the electrical effects of muscle fibres in the Vortex of the Heart. (4) Sometimes the U wave disappeared in ECG, so that, more investigation for this wave is necessary for an analysis of this wave. | |||||
