- A fluttering in your chest
- Rapid heartbeat (palpitations)
- Shortness of breath
- Lightheadedness or dizziness

In infants and very young children, those who have sweating, poor feeding, pale skin and infants with a pulse rate greater than 200 beats per minute may have supraventricular tachycardia. Some people have no symptoms at all.
