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.

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.
