摘要：
A new method for estimation of changes in the atrial cycle length during atrial fibrillation is presented. The objective is to investigate whether or not respiration, through the autonomic nervous system, modulates the atrial cycle length in patients with permanent atrial fibrillation. A group of eight patients with permanent atrial fibrillation, AV block III and permanent pacemaker was studied during rest, rhythm controlled respiration at a rate of 0.125 Hz, and during rhythm controlled respiration after full vagal blockade using atropine. Using the new method, it was possible to detect a prominent spectral peak at 0.125 Hz during rhythm controlled respiration in two of the eight patients; the spectral peaks disappeared after full vagal blockade.
