Arrhythmia?: You may be having an arrythmia of the heart. Important to sort out if the heart beats are regular or random. You can try and see, but better to see a physician and get a holter monitor to capture this activity. The ordering of a holter can prob be done by any health care provider. It records the rhythm for 24-72 hrs, and should be caught if it happens so frequently.
