Hi.... many thanks if can answer my question...i think i also face this problem - random fast heartbeat...which is sometimes my heartbeat suddently will run very fast..up to 200 per minute and i can not catch up the breath for that time....it will maintain around 30 mins / 1 hour...at that time...i feel very tired and my face is pale.....after that...it will back to normal... is that consider as random fast heartbeat?
Hi, When you feel your heart beats fast It's because the rate has increased. It might be because of simple reason like anxiety or complex on like some problem in the current of the heart.  It is important to know because if the rate and rhythm of your heartbeat is changing then you might require medical help.  I would suggest getting a 24-hour Holder test done to look at the heart rate and rhythm over 24 hours. This will give an idea of whether It's something minor versus a rhythm problem.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
