Diagnostic uses of epicardial electrodes after cardiac surgery.
Dysrhythmias after cardiac surgery are common. The etiologies and treatments are diverse depending upon the origin of the dysrhythmia. An atrial electrogram obtained from epicardial electrodes temporarily positioned at the time of surgery can detect the origin of an anomalous rhythm. This article discusses the diagnostic use of epicardial atrial electrograms after cardiac surgery, types of atrial electrograms, steps to interpretation, and nursing implications. An understanding of their use can facilitate patient management and therapy.
