Not well today

I've had a cold for a week.  Feel rather weak.  Today is Friday, day after Thanksgiving. Monday morning about 3:00 am passed out in bathroom.  Sharon took me to hospital in ambulance.  They said I was in afib.  They called Dr. Feiglis.   They all agreed that the passing out was not caused by the afib.  Newt week on the Holter monitor.
