Is supraventricular tachycardia treatable?

Yes. Eliminating the "short circuit" in your heart responsible for the tachycardia by way of a procedure called ablation (performed in the cath lab) is one permanent way of treating the svt. Medications can also be used to modify the electrical activity of the heart and control the tachycardia. Consult your cardiologist to see if which treatment option suits you best.
