In brief: See Below

Svt: tachycardia means the heart beats faster than normal originating supraventricular, above the ventricles, in the atria caused by abnormal electrical impulses.
Because the heart is not contracting effectively, it may cause lightheadedness, dizzyness or fainting.This arrythmia is usually not dangerous but in a few people it can become dangerous. Your daughter must be assessed by a cardiologist.

In brief: SVT

Normally, the heart beat originates from the the eight upper chamber of the heart and goes to both ventricles.
If there an extra beat originates from any other place, it makes the heart to go into overdrive and and cause svt.
