Ivabradine as an Alternative Therapeutic Trial in the Therapy of Inappropriate Sinus Tachycardia

Abstract

Inappropriate sinus tachycardia is a disease which is relatively rarely found and sometimes difficult to treat. Up to now it has been mostly treated with a β-blocker or verapamil. If this did not work sinus node modulation was considered. Since the relatively new selective IF-stream blocker ivabradine has been approved for the therapy of chronic stable angina pectoris, a new therapeutic option is available. As ivabradine is well tolerated and only few side effects are known, it may become a new therapeutic step between medication and the invasive sinus node modulation. We report the case of a young female patient with inappropriate sinus tachycardia where a sustained therapeutic success was achieved with ivabradine medication as an alternative therapeutic trial after various ineffective medications.
