If you have supraventricular tachycardia (SVT) you’ll usually feel your heart racing in your chest or throat and a very fast pulse (140-180 beats per minute).
You may also feel:
- chest pain
- dizziness
- light-headedness
- fatigue (tiredness)
- breathlessness
On rare occasions, you may faint because of a drop in blood pressure.
When to see a doctor
Although the majority of SVT symptoms are not serious, you should contact your GP immediately if you experience any of the above symptoms.
If you are experiencing severe symptoms of chest pain, feeling faint or difficulty breathing, call 999 for an ambulance.
How long do symptoms last?
Symptoms of SVT can last for seconds, minutes, hours or (in rare cases) days.
They may occur regularly, several times a day, or very infrequently, once or twice a year.
