A very recent stress test confirms he is functioning at 30% of his heart's ability. His pacemaker's battery was replaced a week ago, it only lasted three years, so that tells you it was working overtime. They usually last five to seven years. He finally revealed last night that he is upset that "no one told him" he was that bad off, he thinks I knew about it (I did not not until the cardiologist read the results.) Dad is wanting a miracle from the doctor, it is difficult to discuss the issue with him as he gets agitated pretty quickly. Dementia is also getting worse. Any suggestions on how to cope with this phase? I have a sense that I will find him passed away in his chair one of these days from a major heart attack, he also has a sense of doom now. I know it's coming, but I don't think you are ever really ready. Thanks for listening. . .
