Electrocardiogram (ECG/EKG)
An electrocardiogram (ECG or EKG) is a test that records the heart's electrical activity through electrodes on the skin, producing a tracing of rhythm and conduction. It screens for arrhythmias and ischemia and is routine in pre-operative evaluation before surgery.
What is an electrocardiogram (ECG/EKG)?
An electrocardiogram (ECG or EKG) is a test that records the heart's electrical activity using electrodes placed on the skin, producing a tracing of the heart's rhythm and conduction. The resulting pattern lets clinicians see how the heart's electrical signals are firing.
It is a quick, non-invasive test that can screen for irregular rhythms and signs of reduced blood flow to the heart muscle.
How is an ECG used before surgery?
An electrocardiogram (ECG/EKG) is a routine part of many pre-operative evaluations, helping clinicians identify arrhythmias or ischemia that could raise the risk of anesthesia and surgery. The results inform whether a patient is cleared to proceed.
In an ambulatory surgery center, where cases are meant to be lower-risk and same-day, an unremarkable ECG supports safe patient selection, while abnormal findings may prompt further cardiac review.
