Anyone experience Wide QRS. If so, what symptoms?

I just recently got over being sick and dealing with alot of PVCs, PACs which always happens when i get sick. I ended up going to the ER and they found a Wide QRS while I was there. I was scheduled to follow up with cardiologist which I'll see tomorrow. Today I started feeling that flush weak feeling again and I thought is was remnants of the virus. I started feeling it again this evening and checked ekg and it said sinus rhythm with Wide qrs. I see the electrophysiologist tomorrow and they are rechecking potassium and electrolyte levels. I have not been dehydrated and BP has been slightly elevated but otherwise normal. Has anyone else experienced Wide QRS with those nausea feelings? Thanks in advance...
