My husband, who is very overweight, was hospitalized with a racing pulse a year ago. He underwent a treatment to shock it back to a normal rhythm, and it worked. Last weekend(7 days ago), he overdid some yard work -shoveling rock- and got tired very fast. The next day he and I both developed chest congestion and cough, and I noticed his breathing seemed labored. His blood pressure is fine--around 121/69, or lower--but his pulse is 135-136. ( it was as low as116 one day) HIs cholesterol is great, his BP has been under control. He says he is going to the Dr, on Monday. Should I make him go to the ER, or can it wait?
