NCT01359683

Brief Summary

The purpose of this study is to investigate non-linear heart rate variability indexes as predictors of the incidence of cardiac arrhythmias in patients undergoing cardiac surgery, including coronary artery bypass graft (CABG) and valvular surgery.

Outcome Measures

Primary Outcomes (1)

  • Investigate non-linear heart rate variability (HRV) indexes as predictors of the incidence of cardiac arrhythmias in patients undergoing cardiac surgery, including coronary artery bypass graft (CABG) and valvular surgery.

    Sept 07 - Sept 08

Secondary Outcomes (1)

  • Registration of HRV changes during cardiac surgery, and comparison HRV pre-operatively, post anesthesia induction, on emergence from anesthesia and postoperatively.

    Sept 07 - Sept 08

Study Arms (1)

A

OTHER

This is a prospective observational study. 100 patients in one arm scheduled for cardiac surgery will be enrolled. ECG tracings will be obtained when subject is at rest, in supine position, before induction of anesthesia (within 24 hours prior to induction), after induction of general anesthesia, right before emergence from anesthesia (or before transportation to the ICU if the subject remains intubated), and within 24 hours post-operatively; additional ECG readings may be obtained during the surgery if deemed necessary.
