An ECG provides imformation about what?

What is an ECG and what is it?

An ECG test is a non-invasive procedure that records the electrical activity of the heart at rest. Insight Medical Imaging offers ECG exams on a walk-in basis at most of our locations across Alberta. All ECG exams require a doctor’s requisition, Alberta Health Care card, and photo identification. ECG tests can be used to assess heart rate, rhythm, blood pressure, and other symptoms such as palpitation or chest pain. x-ray.ca/services/walk-in-ecg/
