Per nuclear stress test all is fine. Don't consume caffeine. Don't have anxiety. Still having odd rhythm/dypsnea. Electrophysiology consult?

Yes. An event recorder will allow your ECG to be recorded during symptoms. This will help determine if your symptoms are caused by an abnormal heart rhythm.
Rhythm issues. Possibly. Your rhythm disturbances maybe benign- i don't have the details. If you have on going symptoms then a ep consult may help.
