A new simple method to assess global left ventricular systolic function based on the sum of regional myocardial velocities.
The relations between left ventricular (LV) function and global tissue Doppler velocity, strain rate, and strain were assessed in 99 studies. Significant correlations were found between the LV ejection fraction and global tissue Doppler velocity, strain, and strain rate (r = 0.50, r = 0.63, and r = 0.46, respectively, all p <0.001), suggesting that this global assessment may be useful in evaluating LV function.
