My father died of a massive heart attack at the age of 48...no history of problems. I am now 38 (female) with both of my pregnencies I had pregnancy induced hypertension. Blood pressure returned to normal both times. I have also always had a high resting pulse rate, around 100bpm. about three years ago my ob sent me to see a cartiologist for resting pulse in the 120's and high blood pressure about 135/90. Cardiologist heard my history ran a lot of tests and told me everything was fine, then put me on a beta blocker. Several months later I got off of the beta blocker (he told me it was optional) Fast forward three years. I just had a physical, and she put me on Coreg cr 20mg. My resting heart rate was averaging 105ish blood pressure 145/95. Dropped my pulse to 88ish and bp to 133/84. Raised my Coreg cr dose to 40mg and no change in pulse or bp. All of my tests show nothing. Dr. said it is not a weight issue. I feel fine, but this is starting to worry me. What else should I look into?
