My Husband Has Chf W/15% Ejection Factor....had A Defib/pacemaker Implanted

My husband has chf w/15% ejection factor....had a defib/pacemaker implanted 4 yrs ago. He has maintained pretty good with the exception of hospitalization 2x's for fluid retention. This last week has been a very noticeable change as in constant sweating especially when sleeping and sleeping at least 14-16 hrs a day with no energy at all. His next cardio dr apt is 8/29 but I really would like to take him to the ER. I guess I am looking for an opinion because can't get get any answers fro his dr as he is out of town.
