My husband is a generally healthy and health conscious 47 year old man. In 2012 he was sick three times, a bacterial infection, pneumonia and unexplained racing heart episodes. He went to the doctor for each of these episodes but there was very little explanation as to what caused the issues just treatment. Now he regularly gets sick when he never did before. This week he has been ill off and on all week. He will be well enough to head off to work and come home exhausted and feverish. After a little rest he will improve and be back to his normal self. One night his heart was racing for no reason. 90+ beats each minute when his resting heart rate is generaly in the 70s. I feel like these episodes are tied to the multiple illnesses in 2012. He feels like doctors are just guessing and does not want to go to doctors anymore. Is there anything I can do to get him back to normal?
