@texas14 The sodium (salt) helps with low blood pressure that can come with POTS. I don't know if it does help with the rhythm of the heart. I was underweight when struggling with the low bp. My fast heart rate has happened since I was a child... no matter if I was underweight or overweight or within range with my weight.. or if my bp was in range. The fast heart rate has happened with this salty diet.. but I don't eat salty everyday.. that may make a difference. So far the doctors tell me nothing to be concerned about yet with the fast heart rate. I go through heart test ever once in awhile.

POTS effects the young... teenagers mostly. I am far from that 😁

If it feels like a panic attack it can be scary. I have not been out in public much the past few years and I get panic attacks when I get around many people. I actually ran out of a store a few months back.. before this covid started. Out in the open and a few good breathes and I was okay. I could not bring myself to go back in the store though.
