My garmin watch tells me abnormal heart rate detected when im playing bridge! ? i can feel my heart racing. my issue is that it seems to take a long time before i can use my watch again as the heart just shows. i am not sure how concerned to be. ?

Time to see a doctor: A woman who feels palpitations should be checked by her primary care doctor (family medicine or internal medicine, not Ob-Gyn) to make sure her body is ok from a general check-up point of view, and to listen to her heart. It could be a thyroid hormone problem, or could be that her heart is beating irregularly for another reason, etc... Additionally, a cardiologist can also evaluate.
