title: [Is there a relation between cardiorespiratory fitness and systolic time intervals?].
abstract: Systolic time intervals measured by polycardiography significantly correlated with some spiroergometric parameters of cardiorespiratory fitness both at rest and during dynamic exercise. The correlations were mostly free. There were considerable intraindividual differences. The method of polycardiography can thus not be recommended for exact intraindividual differentiation of left vetricular functional ability. Intraindividual detection of systolic time intervals will be the subject of our further investigation.
