Abstract

Frequency-domain spectral analysis was used to examine the effect of the parasympathetic division of the autonomic nervous system on heart rate in normal, healthy subjects and stroke patients. Stroke survivors are at increased risk for cardiac events such as myocardial infarction and sudden death. Evidence suggests that decrease in heart rate variability (HRV) is a risk factor for arrhythmias and sudden death. Data were analyzed from normal healthy subjects and stroke patients during rest, paced breathing, progressive exercise and recovery periods. which caused changes in the autonomic regulation of heart rate. After analysis, data were compared to see changes in the parasympathetic function in normal subjects and stroke patients. One significant peak (respiration peak) in the heart rate variability spectrum was examined by this technique.
