ECG Tests at Parkhealth Medical Centres in Cape Town

What is an ECG?

An ECG, or electrocardiogram, is a test which analyzes and records the electrical signals in the heart. This test is done to monitor the heart’s overall health and to detect serious problems.

Why is an ECG Done?

An ECG is used to diagnose suspected heart problems such as:

  • Coronary artery disease – Blocked or narrowed arteries in the heart which could be causing chest pain or putting you at risk of a heart attack
  • Arrythmias – Irregular heart rhythm
  • Previously undiagnosed heart attacks

There are certain symptoms that can be experienced which indicate potential cardiovascular illnesses. These symptoms include:

  • Chronic heart palpitations
  • Unexplained shortness of breath
  • Chest pain
  • Chronic fatigue and/or weakness
  • Dizziness, confusion, light-headedness
  • Rapid pulse

An ECG test is not needed in low-risk individuals. In other words, if you are not experiencing any of the above symptoms, or if you do not have a family history of heart problems, you may not need an ECG. Your doctor will advise you further on this.

What Happens During an ECG?

The test takes a few minutes to complete and requires you to be warm and comfortable enough to lie still.

Your doctor will place a number of electrodes on your body, mainly the chest and your limbs. The electrodes are small, sticky patches which contain wires that connect to a special monitor. During the ECG, the system will record the electrical signals produced when the heart beats. The computer then displays the recorded information as waves on a paper or on a monitor for your doctor to analyze.

Any anomalies detected during the ECG will be assessed by your doctor who will then discuss formulate a report before providing you with feedback.

An ECG gives your doctor information about the following:

  • Changes in the structure of the heart
  • Abnormal heart rate
  • Irregular heart rhythm
  • Previous heart attack or risk of future heart attack
  • Reduced oxygen and blood supply to the heart

If you suspect you are at risk of cardiovascular disease, or if you have been experiencing any of the symptoms discussed here, please contact us immediately to arrange an appointment with one of our doctors. Heart disease is serious and early detection ensures effective treatment and prevention of potentially fatal complications.
