A Case Report of Rate Control With Ivabradine in a Patient With Refractory Atrial Tachycardia and Heart Failure

Abstract Background: Already known ivabradine’s effects in decreasing atrial spontaneous activity and in pulmonary veins, the focal atrial tachycardia, New information is that it is candidate for re-entrant atrial arrhythmias.Case presentation :An 85-year-old woman with a history of underlying ischemic cardiomyopathy complained of worsening heart failure symptoms due to rapid atrial tachycardia, which was resistant to several rate control drugs but responded well to ivabradine. An electrophysiology study demonstrated a roof dependent macro-reentrant tachycardia of the left atrium. Linear ablation at the left atrium roof resulted in termination of the tachycardia. Conclusion: Ivabradine can be used as an effective rate controll drug of reentrant atrial tachycardia.
