There is one symptom that is really bothering me more than usual for the last month. I get these heart pounding with skipped beats. I can be sitting down and then upon moving slightly on the sofa my heart rate increases by 20 beats a minute and more troublesome is that my heart pounds pretty uncomfortably in my chest and every 5 or 10 beats it missed a beat and then gives a great big thud with a strange sensation in middle of the chest. This can last for up to an hour or so and can reappear later in the day. This tends to happen during periods where I dont feel so good as this week I have been sofa/bed bound. Also when standing up or walking get some pretty heavy thuds quite often. Does anyone else get this, any idea what this is due to? Could it be lack of energy to the heart?
