Supraventricular tachycardia (SVT) causes episodes of a fast heartbeat. 'Thumping heart' sensations (palpitations) and other symptoms may occur during each episode. Regular medication can prevent episodes of SVT. Another treatment option in some cases is to destroy a tiny part of the heart that triggers the SVT.
