bradycardia and enlarged right ventricle

[dadof7]

I have had asymptomatic bradycardia (45) since I can remember but noone questioned it b/c I was athletic.  My GP thought I should get an echo which revealed enlarged right ventricle 3.3cm mild mitral regurge and a trace of tricuspid regurge.  The rest of the echo was normal.  Is  3.3cm really large for the right vent and is it related to the brady that has been present most of my life.  Also should I be exercising or can it worsen the problem
Thanks for any input

I also have bradycardia and my recent echo was similar to yours.  After further testing, I was ultimately diagnosed with severe sleep apnea.  I never even knew I had it.  Do you snore and/or wake up tired in the morning?  If so, you may want to ask your doctor about a sleep study.
