[|Human|] I am 51 years old in  good shape, thin and exercise.  Lately I noticed nail beading on several of my finger nails and shortness of breath at times doing minor things like sweeping or throwing a ball or just turning over in bed.  I feel like I ran a mile. no chest pain just  have to breath hard and heavy...I also feel jittery like I have had too much caffeine but do not drink coffee or caffeinated beverages. I feel my heart doing flip flops, I have low blood pressure about average 100 over 57...and taking no medications I do not have anxiety or asthma. my primary said my heart has "extra beats" ...whats wrong
[|AI|]  Hello. The heart grows old with us, unfortunately. It has a certain rhythm to do its job, so we can do our everyday things and help us do some extraordinary things. In order for this rhythm to be on cue/on time the heart has an electrical system to keep in sync. This sometimes gets off track as we grow older. Sometimes it can be caused by a clogged heart artery supplying the system. Further investigation by a heart specialist might clear up this problem for you. Hope this helps
