Summary
A Reddit user said long COVID began three months after a COVID infection, with tachycardia as its first and most frightening symptom. An attack sent them to the ER, where the heart returned to normal, and a battery of tests was inconclusive. They later took LDN and NAC and reported no tachycardia attacks since August.

They say too little about how ill they were at each step to draw it on the severity scale, so the steps are listed as they describe them. Dates are when they posted.
