Two Extremes of Classically Normal Electrocardiograms, a Concave RS-T Elevation with a TU Fusion and a Gently-Sloped ST-T Segment with an Accentuated U Wave, Disclosed by Reaction Patterns in a Five-Minute Postural Test

抄録

Changes in the regulatory mechanism of the autonomic nervous system affect almost all organs including the cardiovascular system. The changes in the autonomic nervous system can be caused by an extremely abnormal mode of daily life such as a severely muscular (especially in athlets) or mentallytense daily life on one hand and a recumbent, sedentary or mentally-relaxed daily life on the other hand. Previously, the author indicated the possibility of electrocardiographic dif-ferentiation of an overload (abuse) and an overprotection (disuse) of the autonomic nervous systeml. This paper deals with electrocardiographic manifestations of these two extremes of vegetative cardiovascular disturbances.
