5 years ago in my echo LA - 31 mm, Last year LA - 40 mm at one centre, LA - 38mm at other centre Now recent echo LA - 33 mm, and 34 mm at two different centre..rest all measurements are normal and almost same since 5 years.. But at that time my HR was a above  100bpm and tachycardia was there... I am a cardiophobia, health anxiety, death anxiety patient sive 5 years.... Somewhere I have read that RCM also have that same pattern like LA enlargement So I got worried about that ... My question is tha is it my anxiety there is something else I echo... please guide I am attaching some of my reports, One is of 1 year ago and other one is latest.
