In brief: Complex
Usually it is caused by an electrical abnormality in the atria .
It can be dangerous if it causes the heart to beat too long. But the. Patient would definitely feel it and know something is wrong. When the heart beats in svt for a long time there is a risk of heart failure or even cardiac arrest.

It is complicated. Often there is an electrical path that loops around and around and bypasses the supposed regegating sinus node. Treatment depends on how long you are in SVT, how fast your heart goes and can be by trying for permanent conversion to sinus rhythm rate control with meds only or destruction of th abbé rant pathway. Hope this helps& you feel better!

In brief: Usually genetic
Svt is a hodgepodge of many different diagnosis, it is most likely hereditary, but it can be rarely related to heart disease or hyperthyroidism, or pulmonary hypertension.
Most instances, svt does not cause any long term heart damage as long as the heart rate is under control, either with medication or an ablation to burn the area of focus of the svt.
