[|Human|] Hi. I was sitting down and my heart out of nowhere just started beating fast like six beats and then went back to normal. My heart has done this thing where it pause and then start beating again but never has it beat that fast without me doing anything to make it do that. What causes this to happen?
[|AI|]  What you describe might be a transient arrhythmia, where the heart misfires for a small-time and regain s normal heart rate soon after, we should know what is the rhythm to know the reason.  Best is to get a EKG done at the time of episode, if it's a happens Daily than a 24 hour holder.  If it's too rare but troublesome something called event recorder.  In some probabilities what you feel might be subject with normal beating of the heart where all the test about may come negative, in such a would reassurance as nothing being wrong either your heart All the above discussion is to find directions the reason behind the increased which you can follow only if your episode is more sever, lasts longer or is frequently happening otherwise you may just forget about it Regards
