About this trial

This is an interventional diagnostic trial for Cardiac Arrhythmia

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • All patients who will have cardiac surgery
  • The patient must be mentally able and willing to participate in the study
  • Male or female patients over the age of 18

Exclusion Criteria:

  • Patients with major renal, hepatic, respiratory, or cerebral dysfunction
  • Patients with atrial fibrillation or other forms of sinus node dysfunction
  • Patients requiring continuous artificial pacing
  • Patients with significant congenital heart disease with or without arrhythmias
  • Patients on Intra-Aortic Balloon Pump
  • Patients experiencing cardiac emergencies or undergoing cardiac salvage operations

Sites / Locations

  • Hahnemann University Hospital

Arm Label

A

Arm Description

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.

Outcomes

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.

Secondary Outcome Measures

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