right sided pain after exercise

[KAD]

Thank for this service and your time.  Sometimes after I exercise I get this pretty bad pain on the right side of my chest.  I am 28yo female with atrial pacemaker for IST ablation gone bad.  Pacer put in 1 year ago.  I am in pretty good shape and exercise 1 hour a day mon-fri.  About 1 hour after walking last week, I was shopping and got this really bad pain on the right side of my chest.  It gets more severe with a deep breath and leaves me a little short of breath.  Sometimes I will break out into a sweat with it also. Do you think it is the pacemaker doing this?  It doesn't feel like my heartbeat is unusually slow or fast at the time.  It then will just spontaneously go away after about 20 minutes or so. Do you think it is muskulosketetal or GI related?  I don't really ever have GI problems.  Occasionally my electrolytes are abnormal.  And I am watching my weight very carefully.  Could my K+ level have anything to do with it?  MD checked my K+ level once and it was kind of low-3.0.  I have AAIR pacer and use it 95% of the time.  Thanks in advance for any thoughts or suggestions.

this is probably totaly unrelated to your chest pain in rght side  during exercise,  but i've read that people usually exhale when their right foot hits the ground while running/jogging which causes the liver to be stessed somehow and cause right sided cramping.  While running, try exhaling when your left foot hits the ground,  Like i said,  it is probably not what you're feeling, but maybe worth a try.  good luck

KAD,

Thanks for the post.

Your symptoms really do not sound cardiac or related to your pacer.  The quality and timing of your symptoms sound more pulmonary in nature, one thing that comes to mind is occult Asthma or reactive airway disease.   Your electrolytes really shouldnt have any of this type of effect either.

I would discuss the symptoms with your physician.  Also,  keep up the exercise.

good luck
