Hi... Welcome to HEALTHCARE MAGIC... I have gone through your query and can understand your concerns... Heart palpitations can be bothersome or frightening. They usually aren t serious or harmful and often go away on their own. Most of the time, they re related to stress and anxiety or to consumption of stimulants such as caffeine, nicotine, few Medications or alcohol. Palpitations also often occur during pregnancy. As you mentioned that you had physical tests and all have been normal. I will advise you to do necessary lifestyle changes like: •Reducing anxiety and stress. Common stress-management therapies include relaxation exercises, yoga, tai chi, biofeedback, guided imagery, and aromatherapy. •Avoiding certain foods, beverages, and substances. This may include alcohol, nicotine, caffeine, and illegal drugs. •Avoiding medications that act as stimulants. These include cough and cold medicines, and certain herbal and nutritional supplements. If lifestyle changes fail to reduce or eliminate palpitations, you should consult with a doctor. Hope this information helps... Thanks & Regards, Dr.Shiwani
