General & Family Physician,  's  Response
Hi lithium in high dose can affect thyroid hormone production. Are u still taking lithium? Tiredness can be because of lack of thyroid hormone. Considering that you have a cardiac history the possibilities for loss of breath can be many. It's advisable to meet your doctor to get a better idea of the cause of your symptoms and appropriate treatment. I wish you good health. Take care :)
