Cardiology : If that's true you need to see a Cardiologist to determine if you have AV Nodal reentry tachycardia or another dangerous tachyarrythmia that may need to be mapped, ablated, or otherwise controlled. Beta blockers can slow your heart rate but the rhythm must then be identified cardioverted and controlled by pacemaker or pharmacological means. You need a holter monitor and stress test. See cards.
