  Purpose

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.

Further study details as provided by Drexel University:

Primary Outcome Measures:
  • 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. [ Time Frame: Sept 07 - Sept 08 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Registration of HRV changes during cardiac surgery, and comparison HRV pre-operatively, post anesthesia induction, on emergence from anesthesia and postoperatively. [ Time Frame: Sept 07 - Sept 08 ] [ Designated as safety issue: No ]

Estimated Enrollment: 100
Study Start Date: September 2007
Arms Assigned Interventions
A
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.
