Dysrhythmias under General Anesthesia and Their Management

Cardiac arrhythmias during anesthesia are common and almost benign, with the incidence ranging from 60 to 90%. Arrhythmias are one of several significant predictors for severe cardiovascular outcomes. It is essential, therefore, for the anesthetist to evaluate patients at risk preoperatively with a careful history and to have an appropriate knowledge concerning the etiology, electrophysiology, diagnosis, drug effects and treatment of arrhythmias.
