I have been feeling like my heart is racing. Have chest discomfort. I have had a stress test a couple of time, but it shows nothing. I have been walking and trying to do a slow job. Can not jog very very far. Walking has been good. No Dr. can seem to find out what is wrong. They all tell me it is stress. I have lost 15 pounds so my weight is good.
If you have lost weight and your heart is racing, you must first check for hyperthyroidism. To look for a cardiac lesion like mitral valve prolapse causing palpitations you need an echocardiogram. For heart rhythm abnormalities, please get a 48 hr holder. The loss of weight however is not explained by the above cardiac lesions in which case you need to be evaluated for other causes.
