A 40-year-old man with severe sleep apnoea syndrome presented significant s
inus pauses during a 48 h electrocardiogram Holter recording. Holter analys
is showed one sinus pause of 6.4 s duration, and many pauses greater than 3
s. The 48 h Holter reevaluation, after a continuous positive air pressure
device was applied, showed no pauses. The electrophysiological study was ne
gative for sick sinus syndrome. (C) 1998 Elsevier Science Ireland Ltd. All
