N2 - Dynamic measures of heart rate variability (HRV) and baroreflex sensivity (BRS) may uncover the postoperative course of patients undergoing cardiovascular surgery. 162 patients participated in a prospective study; Cardiovascular signals were recorded the day before, 24h after surgery, one week and three month after surgery. Time domain parameters of heart rate variability showed a significant (p=8,9·10-9) decline 24h after surgery and a significant recovery (p=0,00049) first week after surgery. The bradycardic and tachycardic regulation strength regenerated similar. Furthermore the number of tachycardiac regulations decreased significant (p=) within the first week after surgery. The HRV and BRS parameters of the autonomic system obviously show a tendency towards recovery after coronary artery surgery.
