An ECG, or electrocardiogram, is a simple test that monitors your heart’s rhythm and electrical activity.
It is used diagnostically to determine if you have any heart issues and can be conducted at our clinic by one of our cardiologists or trained specialists.
An ECG test takes only a few minutes, and you can resume your normal activities immediately afterwards. It can also be performed while you are using a treadmill or exercise bike (stress ECG) or while you go about your daily activities (ambulatory ECG), allowing the heart to be assessed under different conditions.
The type of ECG recommended will depend on your symptoms, such as whether they are triggered by physical activity or occur more randomly. Our experienced specialist cardiologists can perform these tests in the clinic, if appropriate, to diagnose the cause of any symptoms you may be experiencing.
An ECG is a non-invasive diagnostic test that records the electrical activity of the heart over a period of time. During an ECG, electrodes are placed on specific areas of the body, typically the chest, arms, and legs. These electrodes detect and record the electrical impulses generated by the heart.
The data collected is then processed by an ECG machine, which produces a detailed graph reflecting the heart’s electrical activity. By translating these electrical signals into a graphical representation, an ECG provides valuable insights into the heart’s rhythm, function, and overall health.
An ECG is usually suggested if you are experiencing symptoms of a heart problem, such as chest pain (angina), palpitations (where you feel your heartbeat very strongly), dizziness, and shortness of breath. Conditions it can diagnose include:

It is best to avoid caffeinated drinks and foods before your appointment, as caffeine can affect your heart rate. Choose clothes that allow easy access to your chest area, such as a loose-fitting top or shirt. Let us know if you are taking any medications or if you have any pre-existing conditions. Unlike some tests, you do not need to fast before an ECG.
You can resume your normal activities immediately after the test. Our medical professionals will review the results and provide you with a detailed explanation. They will discuss any findings and recommend further steps if necessary. If needed, your doctor may schedule follow-up tests or appointments based on the ECG results.
