Abstract
Emergency treatment for premature contraction is unnecessary in most cases, though premature atrial contraction (PAC) and premature ventricular contraction (PVC) are among the most common arrhythmias observed in the perioperative period. PACs during the perioperative period are associated with perioperative atrial fibrillation. The conventional viewpoint suggests that perioperative atrial fibrillation is less likely to affect the survival of patients when compared with chronic atrial fibrillation. However, more recent reports suggest that perioperative atrial fibrillation is associated with a significant incidence of various complications, including cardiovascular events, renal failure, infection, and cerebral infarction. Thus, caution must be exercised in patients with PAC. It is also necessary to rule out PVC without accompanying myocardial ischemia, because PVC associated with myocardial ischemia can develop into ventricular fibrillation. The causes and sequelae of premature contraction should be checked for in patients who show perioperative extrasystoles.
