My heart races when I am resting, eating, sleeping. I can feel it moving in my chest & if I look down, I can see & feel it thumping. It has been doing this for a couple of months. I am awaiting some heart test from my doctor, but I am really worried as to what this means or if I am on the verge of something serious or life threatening happening. I am on meds for various health conditions, but not for my heart. My blood pressure has been normal but last month it was 140/90. I do have depression and anxiety, but this heart thumping & racing extremely fast is new. Why is this happening.
