ANAESTHESIOLOGY AND INTENSIVE CARE The influence of epidural anesthesia on the electrical activity of heart atria
Journal: Polish Journal of Cardio-Thoracic Surgery
Year: 2014

Regardless of its location, epidural anesthesia and sympathetic blockade associated with this procedure do not significantly affect the electrical functions of the cardiac atria reflected in superficial ECG, including the electrocardiographic parameters that are considered to be markers of increased risk of perioperative atrial fibrillation, such as P wave dispersion and its maximum duration.
