                                                          Hi,                                                                                                                In archives of the forum  I found three different normal  values for left atrium and left ventricle.               left atrium                                3.0-4-0cm     left ventricle end diastolic diameter      4.5-5.6cm     left ventricle end systolic diameter       3.0-4.0cm                                                               left atrium                                3.0-4.0cm     left ventricle id(dia)                     3.5-4.5cm     left ventricle id(sys)                     2.5-3.5cm                                                               left atrium                                3.0-4.0cm     left ventricle                             4.0-5.0cm     left ventricle                             3.0-4.0cm                                                               What are normal values of left atrium and left ventricle for a  (a) sedentary man, (b) a man who exercises a lot and (c) athletic man? What is the difference between left ventricle end diastolic and systolic with left ventricle iddia+idsys. Is left atrium normal value same as left ventricle idsys? In archive I found out that normal ejection fraction is >55 but does not say  up to what number. What is normal ejection fraction range? Is it better if it is on low, average or high side of normal? Thank you for your time. Bob
