i had 2 heart attracts 12 months ago followed by 4 stents. It is my 5 th week on vacation in Paris France. I have noticed my heart fluttering. I take my medication daily. Prior to my heart attacks ( cardiomyopathy) I was in good health with normal blood pressure and normal cholesterol. I do not smoke and limit my alcohol. I feel good and have no other symptoms. Should I be concerned?
