Study Summary
Hypothesis- Radiofrequency ablation, targeting the sympathetic input of the sinus node identified by 20Hz stimulation at the junction of the superior vena cava and the right atrium, will effectively reduce sinus rate acutely and will reduce palpitations due to inappropriate sinus tachycardia without the need for pacemaker implantation due to sinus node dysfunction post ablation.
Interventions
- PROCEDURE electrophysiology study and radiofrequency ablation
