Abstract
We report the case of a 16-year-old boy with cardiomyopathy induced by inappropriate sinus tachycardia (IST). The patient was resistant to treatment with conventional rate-decreasing medications. Therapy with the selective sinus node If current inhibitor ivabradine was started. After 3 months of ivabradine therapy, an improvement in ejection fraction and a successful decrease in heart rate were observed. No side effects occurred. We suggest that ivabradine, currently used to treat stable angina, could be considered as a second-line treatment in patients with symptomatic and refractory IST.
