Abstract

Hörnchen et al., Long term cardiorespirography J. Perinat. Med. 11 (1983)32 H. Hörnchen, R. Betz, F. Kotlarek, P. Roebruck Departments of Pediatrics (Director: Professor Dr. H. Schönenberg) and Medical Statistics and Documentation (Director: Professor Dr. med., Dipl. Math. R. Repges), Medical Faculty, RWTH Aachen URBACH et al. [39] and RUDOLPH et al. [35J described as early as 1965 a loss of heart rate variability in severely ill newborns. Similar observations were made by EKERT and KÖHLER [6] and HON and coworkers [15]. Maturity [21, 36] and age [41] evidently influence heart rate variability as well. The present study aimed to investigate the role of machine processed parameters of heart rate variability for the evaluation of the status of premature and term newborns. 1 Methods and patients All studies were made with the apparatus described in parti.
