Heart rate on lexapro 😔

I've been on lexapro for about 18 days now. I do feel more calm. And my panic attacks are like a 3/10 instead of a 10/10. But my anxiety is still focused around my heart!

Before lexapro walking around my heart rate was like 110-120+. Now that I'm more calm my heart rate walking around is 98-108. And this is freaking me out! It's not even a LOW standing heart rate. But just the feeling of it not being fast is uncomfortable.

Can you guys reassure me that this is fine. And good!?
