I have been suffering sudden pain in chest mainly in the mid portion of the heart for more than one month.i have done ECG,PFT,X-RAY and all BLOOD TESTS. but every report is normal without any single abnormalcy in report.and now I have done the ECHO CARDIOGRAPHY yesterday and found that everything is normal but
LEFT ATRIUM---44mm(20-40)
RIGHT VENTRICLE(diastole)---27mm(06-23)
L.V.E.F----63%
my weight is 76 and I do nt take any alcohol or smoke.
so I want to know what is the cause of sudden pain with feeling of restlessness ??
