✦ Synopsis
The heart rate variability power spectra is computed using an on-line microcomputer system. In normal subjects (n = lo), standing and post-exercise states demonstrated statistically significant increases (p < 0.05) in the peak power at 0.1 Hz. During exercise, the peak power at 0.1 Hz was reduced significantly (p -z 0.05). In patients with myocardial infarction, either the peak at 0.1 Hz or the peak associated with breathing frequency was augmented. Our system is mobile and is useful especially when on-line heart rate variability power spectra are required in experimental or clinical situations.
