A resting ECG, also known as a resting electrocardiogram, is a simple and non-invasive test used to record the electrical activity of the heart. It provides important information about the heart’s rate, rhythm and electrical signals while the patient is lying comfortably at rest. At Hout Bay Family Medical Centre, our doctors may recommend a resting ECG as part of an assessment for certain symptoms, an existing medical condition or a general heart health evaluation. The procedure is quick, painless and can be performed conveniently at our family medical practice in Hout Bay, Cape Town.
Every heartbeat is controlled by electrical signals that travel through the heart and cause its chambers to contract. A resting ECG records these signals and displays them as a series of lines or waves that can be assessed by a doctor.
The test can provide information about how quickly the heart is beating, whether the heartbeat is regular and how electrical signals move through the different areas of the heart. An ECG does not send electricity into the body and simply records the heart’s existing electrical activity.
A doctor may recommend a resting ECG when investigating symptoms that could be related to the heart or circulatory system. These may include:
A resting ECG may also form part of a broader health assessment for patients with high blood pressure, diabetes, a known heart condition or a family history of cardiovascular disease. It may be performed before certain medical treatments or used to assess how prescribed medication could be affecting the heart.
During the procedure, you will be asked to lie comfortably and remain as relaxed and still as possible. Small adhesive patches called electrodes are placed on specific areas of the chest, arms and legs. These electrodes are connected to the ECG machine, which records the heart’s electrical signals.
You may need to remove clothing from the upper part of your body so that the electrodes can be positioned correctly. In some cases, a small amount of chest hair may need to be removed to help the electrodes adhere properly.
The recording itself usually takes only a few minutes. The procedure is painless, although there may be slight discomfort when the adhesive patches are removed.
The ECG tracing can help your doctor assess the rate and rhythm of your heartbeat and identify certain changes in the heart’s electrical activity. An abnormal result does not always mean that a serious heart condition is present, and the findings must be considered together with your symptoms, medical history and physical examination.
A resting ECG records the heart during a brief period while you are at rest. Some intermittent heart rhythm problems may therefore not appear during the test. Depending on your symptoms and results, your doctor may recommend further investigation, monitoring or referral to an appropriate specialist.
