I have been diagnosed with a prolapsed mitral valve 10 years ago. At nite time especially in the recumbent position it is more noticeable my irregular heart beats. The heart beats can be so irrgular it is almost like popcorn inside of my chest cavity. That it keeps me awake at nite time. I have had an ekg and it was read as negative 2 years ago I am wondering it depends on the day time and who actually does it. I also had a 24 hour heart monitor and the person put it on wrong they said. Yet a nurse told me that she can actually feel the irreular heat beats when she takes my pulse and anyone can. It is very easy. Once I went into the ER and the nurse said Oh you acutally can feel your irreuglar heart beats? as I said I felt that one! as she was looking at my heart monitor. Would it help if I elevated the head of my bed about 2 inches up so the blood wouldnt flow backwards into the wrong leaflet of my heart? Could this be what is causing the irrgular heart palpations at nite time? I have noticed also when I gain weight that the palpations also coincide so now I am trying to get back down again to my idea goal weight again my heart acts better this way. good advice only please! no nonsense please I am a female 5 4 and I weigh 160 pounds I am over weight and I am trying to loose now I work out daily and I started riding my stationary bide last week with my work out I usually am not at this weight and my irrg heart beats increase esp at nite time and it keeps me awake till 4 or 5am yes I get chest pain occasionally if I get under stress so I immediately relax myself and stay away from high stress I am also epileptic. right now I have eplitictologist in such a disaray wanting to know what are minature seizures and which are irruguar heat beats from my prolapsed mitral valve I can feel them both if only I could get the cardiologist and neuro to work together maybe I just need a good vacation in taheetee or however you spell it!
