Hello,
Please look into Postural Orthostatic Tachycardia Syndrome (POTS). It is a very unheard of nervous system disorder that prevents the body from being able to properly adjust to the pull of gravity. Therefore, symptoms arise, such as: rapid heart rate upon standing, low or high blood pressure, dizziness, fainting, fatigue, sweating, anxiety-like symptoms, headaches, shortness of breath, inability to exercise, digestion problems, etc. The symptoms are endless and vary person to person day to day. Very few doctors are familiar with this illness and often misdiagnose patients.
Please feel free to contact me if you have any questions.
Best wishes,
Brandi
Do you have a question? How rapid is your pulse? I think it is possible the lupus may be contributing though I don't know that for sure. Have you been to a cardiologist to get checked out? If not you might want to get a work up of your heart. If it is all fine then your rapid beat may be caused by something outside the heart that you can work to correct and hence correct the fast beat or you may just need some meds to regulate your rapid beat. Take care.
