[|Human|] I was sitting here at the computer and all of a sudden my heart was beating really fast.  I got a head rush an then my head slowly turned back to normal.  I tried to do some breathing to see if it help.  I could see my chest moving really fast and then I felt my heartbeat go back to normal.  I just ate lunch not sure what caused this.  It happened one time at work about two weeks ago also.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should rule out arrhythmia (rhythm disturbances in heart) in your case. Arrhythmia can cause rapid heart rate, chest movements, head flush etc. and if not treated promptly, arrhythmia can be life-threatening. So better to consult cardiologist and get done 1. ECG 2. 2d echo 3.  Holder monitoring (24 hours continuous recording of ECG). You may need anti arrhythmia Chat Doctor.  Don't worry, you will be alright. But first diagnose yourself and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
