High-resolution digital Holter recording was
carried out in 21 patients (15 men, 64 ± 12 yr) with chronic
atrial fibrillation. Dominating atrial cycle length (DACL) was derived
by frequency domain analysis of QRST-reduced electrocardiograms.
Daytime mean DACL was 150 ± 17 ms, and nighttime mean was
157 ± 22 ms ( P = 0.0002). Diurnal fluctuation in
DACL differed among patients: it tended to be virtually absent in those
with a short mean DACL, but in those with longer DACL the night-day
difference was as much as 23 ms ( R = 0.72, P |

High-resolution digital Holter recording was
carried out in 21 patients (15 men, 64 ± 12 yr) with chronic
atrial fibrillation. Dominating atrial cycle length (DACL) was derived
by frequency domain analysis of QRST-reduced electrocardiograms.
Daytime mean DACL was 150 ± 17 ms, and nighttime mean was
157 ± 22 ms ( P = 0.0002). Diurnal fluctuation in
DACL differed among patients: it tended to be virtually absent in those
with a short mean DACL, but in those with longer DACL the night-day
difference was as much as 23 ms ( R = 0.72, P < 0.001, correlation of mean DACL to night-day
difference). Mean DACL also correlated with ventricular cycle length
( R = 0.40, P < 0.001), particularly at
night ( r = 0.49). The shorter cycle lengths found in
this study during the day are consistent with sympathetic and/or other
physiological modulation, but since increased vagal tone shortens
atrial refractoriness in most models, parasympathetic influences are
not likely to play a major role. Alternatively, atrial effective
refractory period may not be the sole determinant of atrial cycle
length during atrial fibrillation.
