Well, if this is genuine and not a time wasting hoax
, you seriously need to get to the hospital immediately. Why do I say hoax? because the only thing which can produce a clicking sound in the heart is the mechanical valves and you would need a leaflet to be hanging off for such a loud sound, but even then it would be a different sound. According to your sample, your heart rate was in excess of 170 bpm at the start which is ridiculously high unless you had just run a marathon.
