What symptoms does atrial tachycardia cause?
Symptoms vary greatly. Most people either have no symptoms at all, or are simply aware of palpitation (rapid beating in the chest). Occasionally, atrial tachycardia causes breathlessness, dizziness, or chest pain. If your tachycardia is very fast, you are more likely to notice the difference between your normal heart rhythm and an episode of tachycardia. Young people with healthy hearts are, for some reason, often more aware of symptoms than older people, in whom a modest increase in the heart rate may go un-noticed.
