Popis: | Objectives: The differences in orthostatic blood pressure result from dynamic changes in the sympathovagal balance. We studied sex-related variations in autonomic tone regulation. Study design: The study included 237 individuals (114 males, 123 females) who were asymptomatic and had no abnormal laboratory or physical findings. The mean age was 47 years (range 20 to 79 years) for men, and 39 years (range 20 to 71 years) for women. All the participants were subjected to a careful history taking, physical examination, routine biochemical examinations, electrocardiographic recording, 24-hour Holter monitoring, and orthostatic tests. Results: In heart rate variability analysis, parasympathetic tone parameters, in particular the high frequency (HF) component was significantly high in females, whereas sympathetic tone parameters, in particular the low frequency (LF)/HF ratio was significantly high in males (p |
