What are the symptoms of arrhythmia? icon plus
Symptoms of cardiac arrhythmias are varied both in their type and severity. Dependent on the type of heart rhythm problem you have, you may experience:
- Blackouts or fainting (syncope)
- Chest pain
- Dizziness or lightheadedness
- Palpitations
- Peeling that your heart is racing
- Shortness of breath
- Stroke
- Tiredness or fatigue
Arrhythmia often occur in normal hearts but can also be associated with underlying conditions such as heart diseases and thyroid conditions. Certain factors such as stress, excess alcohol, caffeine and certain drugs can also trigger arrhythmia, with no clear cause always easy to define.

How is arrhythmia diagnosed? icon plus
If your GP or consultant thinks you might have arrhythmia, there are a number of outpatient tests available. We'll discuss your symptoms with you and determine the best approach with the help of our experienced consultant electrophysiologists.
Tests we offer to help diagnose arrhythmia include:
- electrocardiogram (ECG)
- ambulatory electrocardiogram
- echocardiogram (an ultrasound scan of the heart)
- implantable loop recorder
- electrophysiology studies (EP studies)
- cardiac stress test
Dependent on how easy it is to diagnose, or if indeed you have an arrhythmia, your consultant may carry out one or more of the above tests. They will likely be repeated over time in order to monitor your progress and the effects of your treatment.
