Okay so it's been about a year since I've started having heart issues. Fast heart rate, weird sensations in my body, low dystolics, shortness of breath at times... I have been to several cardiologist who say it's inappropriate sinus tachycardia. However it still has not resolved like they thought. My pcp thinks I have long covid. I only got one shot and I caught covid several weeks later. I didn't do bad with the shot I had covid for a minute but I made a full recovery. I didn't feel anything for months then these issues struck one night after drinking. My question is did anyone have a period where they were fine and then the long covid hit them?

Thanks!
