[|AI|]  Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. I will try to explain you something and give you my opinion. This heart racing has to do with a rhythm issue. There are some electrical impulses that generates from a part of the heart different from normal sinus rhythm. They can cause a premature heart contraction that we call extra systolic beats or different arrhythmia like atrial fibrillation. This rhythm heart issues can cause heart palpitation, flattering sensation or heart racing. You might experience anxiety, nausea, difficulties in breathing deeply, chest discomfort, sweats. There are different causes of this rhythm issue like simple stress, coffee and alcohol consumption.  Also, pathologies like anemia, hyperthyroidism or ischemic heart disease might be other causes. So, if I was your treating doctor I will recommend some examination like an electrocardiogram, a cardiac echo to evaluate heart function and walls and the most important one holder rhythm monitoring to see what happens with your rhythm during day and night. After all this we can better understand what we are dealing with and how to treat the problem. Hope I was helpful. Wish you good healthiest regards.
