Does ivabradine help POTS?

Background: Ivabradine is a selective If channel blocker that reduces heart rate without affecting other cardiovascular functions. In case reports and case series, it was shown to improve symptoms in patients with postural tachycardia syndrome (POTS).

Can ivabradine cause fluid retention?

The mortality rate for HF ranges from as low as 5% at year one to 50% at five years after diagnosis, depending on the severity of symptoms, heart function, age, and other factors. The primary symptoms of HF are dyspnea and fatigue, and may also include fluid retention.

Can stimulants make POTS worse?

Although stimulants can increase tachycardia, a recent placebo-controlled trial found that modafinil in- creased orthostatic BP did not significantly worsen standing HR or acute orthostatic symptoms in POTS patients (Kpaeyeh Jr et al., 2014).

When should I stop taking ivabradine?

Ivabradine Is… a “cardiotonic” agent mostly used to reduce symptoms of chest pain and heart failure by reducing the heart rate via inhibition of the pacemaker current. It’s used off-label in postural orthostatic tachycardia syndrome (POTS) to reduce the excessive hearts rates POTS patients experience during standing.
