Lynn, my husband, older than yours, was diagnosed with an ejection fraction of 25% on the left side, more severe.  I'd say get your husband to the emergency room and they should provide you with a Cardiologist on call.  My husband has two Cardiologist and they have referred him to a special Clinic for Congestive Heart Failure Clinic and a Cardio Rehab. My son in law just retired to help me, he was a 40 year Police Commander in Waco, Texas.  My heart and prayers are with you. My husband was a very active Rancher/Beer Distributor, did not drink or smoke and believed in hard work, even at the age of 87, he still worked 12 hours a day. If I can supply you with any info, do not hesitate to get to me. I know how alone it can be. Joyce Loftin 1joyceloftin@att.net
