Postoperative atrial fibrillation (POAF) is a complication that can occur after any operation, but is a frequent complication that occurs in approximately 30% to 50% of patients after cardiac operations (Najmeddine Echahidi, 2008). AF is one of the most common obstacles following a coronary artery bypass surgery (CABG) and is consequently a burden for the patient as well as the hospital (Aranki et al., 1996). Following CABG operations not only is AF commonly found in those patients, but it is also recognized as a major cause of morbidity soon after these procedures (Aranki et al., 1996). The underlying reasons for the development of POAF are currently unknown as each case may vary from one another. Although the cause is unknown, there are some known factors that may play a part in the development of POAF such as increased production of catecholamine, pericardial inflammation, and changes in volume and pressure. These mechanisms can change atrial conduction and refractoriness (Najmeddine Echahidi, 2008).
In a research article from Professional Heart Daily from 2008, the likelihood of POAF development following a CABG procedure and postoperative AF related mortality were considered to guide the study. The observational study consisted of 1832 patients, none of which had AF prior to the procedure, that were undergoing a CABG between January 2000 and December 2005. All the patients in this study were monitored continuously with ECG following the procedure until…
