I m a 66 year old black man who exercises regularly. With medication, my BP is normally 120/73 ... HR between 60 and 70. For the last several of days, my pressure has been around 95/60 with a HR of 37. This morning, it was 100/70 ... HR was 37. Just a few moments ago (2110) it was 104/73 ... HR 43. Should I be alarmed or can I just monitor this for a few more days.
