What are the causes and patterns of electrocardiographic disturbances during cardiac surgery?
What are the causes and patterns of electrocardiographic disturbances during cardiac surgery?
Intraoperative arrhythmias during cardiac surgery are often related to systemic factors like hypoxia and anesthesia rather than the surgical procedure itself.

Highlights modifiable systemic triggers for perioperative arrhythmias; leaves open whether targeted interventions improve outcomes in cardiac surgery.
The electrocardiographic behavior of the heart was observed in 100 patients undergoing heart operations. Most of the arrhythmias were unrelated to the cardiac operative procedure, but as in other thoracic procedures, were related to hypoxia, level of anesthesia, vagal reflexes, and changes in blood pressure. T A and S-T displacements occurred in all groups and were thought to be related to altered dynamics of the right auricle and ventricle. Prevention, recognition and control of disturbances of cardiac mechanism are discussed.
