Heart Rate Variability During Sleep After Fast-track Surgery

December 13, 2011 updated by: Lene Krenk
Based on prior findings concerning sleep disturbances, in particular REM sleep disturbances, after fast-track hip and knee arthroplasty (H-2-2010-011) we performed a supplemental analysis of heart rate variablity after arousals during sleep. We compared preoperative and postoperative results.
