No, tachycardia + neuropathy = dysautonomia (often hyperandrenergic POTs). It’s not a problem with your heart, it’s a problem with the autonomic nerves that control it, which are the same type of c-fiber nerves that are causing your full body burning. This comorbidity of neuropathy/dysautonomia is very well established.
Also wanted to add you can improve this if you get to the root cause of your issue. My POTs mostly went away with IVIG (unfortunately i still have peripheral nerve damage and my neuropahty still flares on IVIG from time to time, just less so, but my POTs is like 90% better). Given yours is happening with food it could be histamine related.
