While some instances of sinus tachycardia may not require any medical intervention and correct themselves, more stubborn or bothersome tachycardia symptoms may be treated with vagal maneuvers, medications and cardioversion techniques, according to Mayo Clinic. Preventing or managing tachycardia sometimes requires catheter ablation or the implantation of a pacemaker or cardioverter-defibrillator. In worst case scenarios, heart surgery may be necessary.
Vagal maneuvers, such as bearing down as if passing bowel movements, medications to control the heart's rhythm, and cardioversion techniques that deliver a shock through the heart that affects the heart's electrical impulses are all common treatments for tachycardia. Medications, such as beta blockers and calcium channel blockers, can help to control fast heartbeats when taken on a regular schedule.
Episodes can also be prevented by catheter ablation, which is a procedure that interrupts the electrical pathway that causes the heart to beat too fast. During the ablation procedure, electrodes are used to damage an extra electrical pathway that causes the symptoms. Another popular option is the implantation of a pacemaker that senses abnormal heartbeats and emits a pulse of electricity to correct it. Similarly, an implantable cardioverter-defibrillator can be implanted into the chest to detect the heart rate and deliver precise shocks to restore the heart's rhythm as needed.
