Recent Diagnosis of POTS but also have episodes of Bradycardia?

I have recently been diagnosed with POTS after failing a tilt table test and being seen by multiple physiscans. What keeps bothering me about the diagnosis is I had a more recent episode where I felt as though I was going to pass out while driving I pulled over and attached a pulse Oximeter to my finger and it read 48 then it shot up to 170. This was noticed on my event monitor reading as well. I was under the impression that with POTS syndrome you typically have an elevated heart rate (which I do most of the time). I’ve asked my physcians about the episode I had and no one can explain why it happened. They have since prescribed me medications to lower my heart rate but I haven’t started them because I am scared that it will mke my heart rate too low in the event that I had another Brady episode.... this morning I woke up feeling pressure in my chest I was still lying flat when I took my heart rate it was in the 100s. I’m so concerned about my heart rate that I feel it’s causing me anxiety. My blood pressure also fluctuates from being either slightly high, relatively normal, or even on the lower side. Is all of this things that I will have to learn to manage with this syndrome? Thanks so much for reading my post and hopefully you can provide me with a more detailed understanding of something that is so complex. Has anyone else had Bradycardia not while lying down and suffer from POTS? Is this all normal? I’m so confused and frustrated at this point.

To be honest 'Bradycardia' is subjective to the person. How old are you? Are you physically active? If you're quite young and/or active then 48 really isn't that low, many Doctors are now trying to shift the old 60-100 beats a minute instead to 50-90. It's possible to have a healthy heart and still have POTS as backwards as that sounds. I agree with the above poster, now you've got this diagnosis you're bound to focus in on it, and the anxiety that creates can have a massive effect on your heart rate.
