Visual evoked potentials (VEPs) were recorded in a group of 20 operators aged 25-45 years during two sessions, before and after a 5-hour work at computer terminals, in order to assess visual system fatigue. The outcomes were referred to the norms established for the age-matched population of 30 subjects not exposed to professional contact with computers.… (More)
PURPOSE The intensity of post-exertion heart rate recovery, evaluated in the first minute of the recovery period (HRR₆₀), is considered to be a strong predictor of risk for cardiac death. Intensification of physical activity performed as part of cardiac rehabilitation (CR) increases the HRR₆₀ value in ischemic heart disease (IHD) patients. In this context,… (More)
A goal of the present work was to analyze the correlation between a course of visual potentials elicited with the pattern stimulation and gender of the examined subjects. VEPs (Visual Evoked Potentials) recordings were performed using STELLA system in a group of 65 healthy adult subjects, with the age ranging from 18 to 70 years, consisting of the… (More)
While testing neurotic patients it was noted that almost all of their complaints concerned physical weakness, easy tiredness, chest pain, heart beating and palpitation. In order to evaluate objectively their physical efficiency, the patients were subjected to exercise test on a treadmill, their ECG, HR and blood pressure being monitored. The exercise test… (More)
Down's syndrome is the most frequently occurring chromosomal aberration which causes, among others, central nervous system (CNS) impairment leading to mental retardation as well as lesions of the sensory analyzers. Contrary to former reports, lesions concerning the hearing organ are relatively common and appear, according to various authors, in 40-78% of… (More)
BAEPs examinations performed in healthy newborns aged up to 14 days of life revealed that in the youngest group (up to 4 days of life) the percentage of the results with delayed peak I latency was relatively high -57.8%. In the further age group (5-7 days of life) the number of the abnormal results decreased considerably down to 14.1%.
