My father is 73 y.o. and has a recent history of heart disease. Last year, he had a stent put in and was feeling better than ever. recently, however, he has had problems sleeping at night due to anxiety that he might have a heart attack. he feels hyper-aware of his heart beat which causes an increase and irregularity to the rhythm. he has started experiencing palpitations and generalized disorientation during the attacks, too. After getting a battery of tests that revealed no problems, he recognized that he is having panic attacks, but is worried that the attacks could lead to a heart attack. I have talked hi into taking yoga (which he had his first class tonight!!!). Any other suggestions for him? Is this common among cardiac patients?

Thank you!!!
