I'm a 14 year old girl and my heart beats faster when I breathe in and it slows down when I breathe out. In 5 seconds (breathing in) it beats 10 times and breathing out for 5 seconds it beats 6 times. Normal? And in a minute it beats 84 times.. hard to count them but roughly around that. =) Thanks
aziz - normal, it is sinus arrhythmia.
