I am a 61 year old female.  My heart rate has always been in the 68-70 rate.  For the past year it is always around 98 or 99.  During the past year I feel tired all the time, along with other strange symptoms.  Heart disease is part of my family history.  Is this a cause for concern?
Family history is a risk factor for heart disease. But it doesn't mean that you are having some heart problem.if you do your all household work including some have exertion and morning walk without any symptoms, then you are healthy...relax and live your health life
