Electrocardiogram
What is an Electrocardiogram?
An electrocardiogram or an ECG is a quick non-invasive method to record the electrical signals of your heart. If you are experiencing heart palpitations, shortness of breath, chest pain, dizziness, or weakness, your physician may refer you for an ECG.
A technician will place multiple electrodes across your chest and limbs while asking you to remain still. They will then capture the electrical signals of your heart for a short period of time.
An ECG can be an effective tool to detect:
Irregular heart rhythm
Structural abnormalities
Arteries that are narrowed or blocked
Previous myocardial infarction (heart attack)
Preparation
Before your ECG
There is no preparation needed. Be sure to bring a list of medications as some medications may affect your heart’s rhythm.
During your ECG
You will be asked to lie on the exam bed while the technician places electrodes onto your chest and limbs. The electrodes assist in reading the electrical activity of your heart. If there is hair on your body, the technician may need to shave where the electrodes will be placed in order to get an accurate reading. The technician will then take a recording of the electrical activity of your heart which is then interpreted by the cardiologist.
After the Test
Unless otherwise stated by your physician, you may resume normal activity after your ECG.
