They can be felt in your chest, throat, or neck. You may Have an unpleasant awareness of your own heartbeat or may Feel like your heart skipped or stopped beats The heart's rhythm may be normal or abnormal when you have palpitations.

sugar levels to look for risk factors. Once you have done that you need to Consult a cardiologist with the reports so get back to me with the reports for a proper consultation.
