I was recently placed on Ivabradine for PoTS with strong tachycardia and elevated BP upon standing. Do you recall about how long after starting Ivabradine you started noticing decreased tachycardia?
Ivabradine (5mg twice a day) was not useful for me. In contrast, my tachycardia decreased with betablockers (propranolol or bisoprolol), although they did not have any effect on my remaining symptoms.
