  • Title: Perioperative cardiac issues: postoperative arrhythmias.
    Author: Heintz KM, Hollenberg SM.
    Journal: Surg Clin North Am; 2005 Dec; 85(6):1103-14, viii. PubMed ID: 16326196.
    Abstract:
    This article reviews current concepts about the diagnosis and acute management of postoperative arrhythmias. A systematic approach to diagnosis of arrhythmias and evaluation of predisposing factors is presented, followed by consideration of common bradyarrhythmias and tachyarrhythmias in the postoperative setting. Postoperative arrhythmias are common and represent a major source of morbidity after surgical procedures, both cardiac and noncardiac. Postoperative dysrhythmias are most likely to occur in patients with structural heart disease. The initiating factor for an arrhythmia following surgery is usually a transient insult such as hypoxemia, cardiac ischemia, catecholamine excess, or electrolyte abnormality. Management includes correction of these imbalances and, if clinically indicated, medical therapy directed at the arrhythmia itself.
