  Electrocardiography (ECG) is a useful monitoring method during anesthesia. Among the numerous ECG parameters, QT dispersion (QTd) is an indicator of instability during ventricle repolarization. According to previous reports, an increase of QTd may be occurred any patients with sympathetic instability. However, almost all such noncardiac patients have a physical status of 1 or 2 according to the American Society of Anesthesiology. Therefore, anesthesiologists should be aware whether the patient’s condition may increase QTd, and should be able to treat unexpected arrhythmia during the perioperative period. Increases in QTd occur during various perioperative anesthetic managements or surgical procedures. Several reports have indicated that stabilizing autonomic excitation with opioids, volatile anesthetics, β-blockers, or magnesium can prevent unexpected ventricular arrhythmia.. View More»
