A New Method to get the LVEF Reference Values of the Healthy Adult Male by Heart Rate and Geographical Environment Factors

ConclusionThe Chinese healthy adult male LVEF distribution showed a downward trend from south to north. Some geographical environment factors have impact on LVEF reference values including latitude, annual precipitation amount and mean air temperature distribution. LVEF is negative correlation with heart rate. When geographical environment factors and individual's heart rate are known, the local and individual's LVEF reference values can be derived from the formulas.
