<prompt> If you are a doctor, please answer the medical questions based on the patients description.One day I went to brush my teeth I felt like I was going to be sick I got some water and sat back down then my body temperature went up I went to get some air and my heart started racing and you could see my heart beating thru my chest what does that mean  <response>: Hello there, and thank you for using Chat Doctor. I carefully read your question and I totally understand your concern. Dont worry, I will try to explain you something and give you some advises. As you describe, my opinion is that we are dealing with a heart rhythm problem. It is difficult to tell what is exactly. You may feel that your heart is racing for different reasons. It may be a simple tachycardia. It means that your heart beats exceeds 100 beats for minute. Furthermore, it may happen for many reasons to simple emotional stress, during physical examination and from other different pathologist. There may be a different rhythm problem. If your heart is beating too fast and in a chaotic way, not rhythmic, it may be what we call atrial fibrillation. If you feel like skipping a beat, it may be an ekstrasystol. So, if I was your treating doctor I will recommend you some simple examinations. Beginning with a blood analyze, an electrocardiogram and an echocardiography. All sow I will recommend a holder monitoring to register and see what happens with your rhythm. If you feel that your heart is beating in a chaotic way. It is advisable to make an electrocardiogram in that exact moment to your nearest cardiologist. In mean time avoid coffee and caffeine products because they exacerbate these symptoms. When we document and see what kind of rhythm problem is this we can talk about treatment. Hope I was helpful. Wish you good health. Best Regards
