Abstract
Ivabradine is used to control heart rate in patients of heart failure with reduced ejection fraction. Although considered safe, it is reported to prolong QTc interval when given with other QTc prolonging drugs or in setting of hypokalemia or hypomagnesemia. Ivabradine causing isolated QTc interval prolongation without any provoking condition is rare. Our patient developed Torsades de Pointes after initiating Ivabradine and her QTc interval reduced after stopping Ivabradine. This may be due to a potential independent dose dependent effect of Ivabradine on QTc interval by its effects on its effects on human Ether-à-go-go-Related Gene (hERG) potassium channels.
