An ECG can also detect other important abnormalities which may need further investigation.
The ECG is performed by one of a team of Cardiac Physiologists or an ECG Technician.
A walk in service is availble with GP or Consultant referral letter
- An ECG records the rhythm of your heart and can detect abnormal patterns which can help diagnose various heart conditions.
- It can help tell if you are having a heart attack or if you have had one in the past. It can also detect irregularities in your heart rhythm. It can sometimes detect if your heart is enlarged or if there is any strain on your heart pumping.
- An ECG is often the first heart test you will have, however it is just a snapshot so you may need other tests too.
Small sticky pads called electrodes are placed on your arms, legs and chest. These are connected to wires that link up to the ECG machine. Your heart’s electrical activity is picked up by the electrodes and the machine prints out the pattern. You will need to lie still because movement can affect the recording.
An ECG on its own may not be enough to diagnose your heart condition but it will show if your heart is beating too fast, too slow or with an abnormal rhythm. Sometimes your ECG can be normal but you may need more tests to definitely rule out a heart problem.
An ECG can also provide clues to how your heart is pumping and if it is enlarged. An ECG done while you are having symptoms can often be more informative.
If your doctor finds irregularities on your ECG suggestive of a heart problem, additional tests may be ordered such as an echocardiogram, Holter monitor, coronary angiogram.
You will not be required to prepare for this test. Please avoid adding moisturisers to your skin as it may prevent the electrodes sticking to your skin and cause delays. Please bring a list of medication if needed.
The procedure is painless. It takes approximately 5-10 minutes to complete the test. You will be required to lie down on the couch if possible. Six small electrodes (harmless stickers) will be placed on your chest and one on each ankle and wrist. These will be attached to wires. You will need to remain as relaxed and still as possible to get a clear recording. The result will be printed. The electrodes will be removed from your skin. Some people feel this like a sticking plaster being removed.
The ECG will be reviewed and reported by the Consultant Cardiologist. It will be sent to your referring doctor within 3-5 working days.
No aftercare is necessary.
