Walk-In ECG

An ECG test is a non-invasive procedure that records the electrical activity of the heart at rest. Electrodes placed on the skin measure heartbeat regularity. This information can be used to assess heart rate, rhythm, blood pressure (hypertension), and symptoms such as palpitations or chest pain (angina).

Insight Medical Imaging offers ECG exams on a walk-in basis at most locations. All exams require a doctor’s requisition, Alberta Health Care card, and photo identification. We do not book appointments for ECG. Therefore, this service is first-come, first-serve. If you are unable to take time off work during the day, we recommend visiting a clinic that has extended hours in the evenings or over the weekend.

ECG vs. EKG vs. Electrocardiogram

Researching ECG imaging can be confusing and frustrating, as multiple abbreviations are used interchangeably with no explanation. While spelling variations may imply various unique exams, all three terms are synonymous, referring to the same cardiac assessment.

The difference in abbreviations stems from language translations between German and English. The German language spells electrocardiogram as elektro-kariographie, hence the acronym EKG. Therefore, there is no actual difference between ECG, EKG, and electrocardiogram.

Electrocardiogram vs. Echocardiogram

Insight Medical Imaging offers multiple types of scans to examine the heart, including electrocardiograms and echocardiograms. These two tests are often confused because they have similar spelling and are often used in conjunction as they are complementary for cardiac assessments. However, each exam provides your doctor and our cardiologists and radiologists with different information, so it is important to understand the differences between both exams.

Electrocardiograms record the electrical activity of your heart at rest using a heartbeat monitor. The monitor records the rhythm of the heartbeat, and our internal medicine specialist analyzes the pattern for inconsistencies.

Echocardiograms provide images of internal structures and how the blood flows through the heart. This exam is done by ultrasound, which uses high-frequency sound waves to investigate the communication and function of your heart’s anatomy, such as valves, vesicles, and atriums.

What Happens During my ECG Scan?

  • After you’re checked in, a technologist will give you a gown to change into.
  • Once in the examination room, you will have six leads placed on your chest, plus one on each arm and leg. We attach the leads as discretely as possible for your comfort.
  • Occasionally, men will opt to take their shirt off instead of changing into a gown, based on their comfort level.
  • One of our internal medicine specialists will review the results and send a detailed report to your doctor. We try our best to send the results as soon as possible, usually within one business day.

Important Notes

  • Please save your questions until the end, as talking during this procedure can change your heart rate and impact your exam results.
  • Sometimes we may need to shave or clean the patient’s chest so the electrodes can be attached properly.


Our technologist will help position you on a bed, where you will lie flat on your back while we attach the leads for your exam.


If you have an Alberta Health Care card or valid healthcare card from out of province, there is no cost for a walk-in ECG procedure (except Quebec).


Typical ECGs take approximately 15 minutes to complete. Exam length can vary based on each patient.
