Abstract
Analysis of heart rate variability in patients with inappropriate sinu s tachycardia showed a 24-hour decrease in all temporal and spectral i ndexes, even after attempted correction to a rate of 75 beats/min. Thi s may have resulted from a global decrease in parasympathetic activity or from a rapid sinus rate produced by other ill-defined mechanisms.
