Yep, same thing for me. My doctor mentioned pectus excavatum about 25 years ago, and I get palps....He said there is a correlation, but I don't notice anything unusual or peculiar other than the palps. He said it is kinda like your chest caves in a bit, changing the anatomical placement of "stuff" inside...but not in a big way.
So, my conspiracy theory about pectus causing my atrial flutter or others complex arrhythmias has no basis? Oh well, not funny... :(
I have pectus excavatum used to be more severe , my case got better with age, always was aware of my heartbeat, with tachycardia and PVCs. one cardio once told me that having pectus excavatum probably made me more aware of heartbeat and thus contributed to the anxiety which caused more palps. Both my sons age 18 and 21 have moderate pectus excavatum, curiously enough they are not heart aware like I am and have never complained of palpitations.I have read that there is a connection between the two, though apparently even some severe cases there appears to be no significant problems.
