hi i have been quite unwell lately on and off,but monday evening was watching tv in bed,when my heart started fluttering i have had these quite often then the rythm goes back to normal after a few seconds but this didnt happen my heart was nearly coming out of my chest and my blood pressure was high and my heart beat was 160 beats per min it was very frightening,the only thing that made my heart go back to normal is when i drifted into sleep and then i jumped in my sleep then my heart beat went back to normal straight away it was very strange
