  • Excitement or excercise (love making included)
  • Exercise, anxiety, drinking lots of caffeinated beverages, coronary artery disease. If its coronary artery disease, there are medications for this, but they also have side effects. They didn't tell me why mine beats fast. In fact she never even named the disease. She told me my heart was doing the cha cha. (eye roll) and I've been on metaprolol tartrate since.

      My mom took that twice a day for several years. It worked effectively, and she eventually got to where she doesn't have to take it any longer.

      Its definitely effective! I've been taking it twice a day for almost ten years. It makes exercise difficult because it doesn't let your heart rate increase with exercise. It makes me tire easily and I can't catch my breath because the blood doesn't supply enough oxygen. They did decrease it though when I went in one day and my BP was 80 something over 50 something. They cut my HCTZ in half as well that day.
    • Linda Joy
      After being hooked up with a heart monitor for a couple of weeks I was diagnosed with a-fib. My cardio oncologist increased my metoprolol and switched to an extended release I only take once a day and added a blood thinner. I asked if I could stop taking the baby aspirin and they said no. They work in two different ways.
