I can not relate to your situation, but I and my wife do have our disorders, mine being rythym disturbances, many of them, and my wife with various conditions, so I in some way can relate to your anguish. Please do not distress yourself to badly, I am sure that your husband will get superb care, and be right back in the pink of things soon. You have come to the right forum, for there are many compassionate and well educatd people here who will support you. my
best to you and your husband.
