Yes. That is correct.

I have both and it took a long time to get the correct diagnosis. I was diagnosed with POTS about 10 years ago but nobody caught the IST until this year. I switched to a new EP that made me wear a holter monitor for two weeks and it showed up. Previous holter monitor was only worn for 24hrs. I was so surprised because I didn’t know it was possible to have both. Have never been able to tolerate beta blockers because they lower my blood pressure too much. Was put on Corlanor and it has improved my life.

Did you end up taking Corlanor afterall? I've been on the lowest dose(2.5mg) twice a day for about two months. It has been life changing for me and helps control my tachycardia. I've tried a lot of the typical POTS medications and haven't tolerated any of them. I was able to use the elliptical machine (up right cardio) at the gym for the fist time in 10 years! I was not told about the pregnancy warning because I'm already on low dose birth control for PCOS but it does mention it in the medication pamphlet. As far as side effects I haven't noticed any so far.
