TRUE OR FALSE

supraventricular tachycardia

1 FALSE SVT is an abnormally fast heart rate of over 100 beats per min. Episodes can last seconds, minutes, hours – or even days, in rare cases.

2 True Anyone, of any age, can have SVT, which often appears for the first time in children or young adults. It’s caused by a problem with the heart’s electrical system.

3 True As well as dizziness, it may cause chest pain, fatigue lightheadedness, breathlessness – and, in rare cases, fainting.

4 FALSE Most episodes are harmless, short and need no treatment. It’s rarely life-threatening, but breathing techniques and medication can help prevent on-going episodes.
