Our goal was to establish normal values for quantitative color kinesis indexes of left ventricular (LV) wall motion over a wide range ages, which are required objective diagnosis regional systolic and diastolic dysfunction. Color-encoded images were obtained in 194 subjects (95 males, 99 females, age 2 mo 79 yr) four standard views. Quantitative magnitude timing function studied age- gender-related differences. Normal limits all ejection filling narrow (< or =25% the mean), with no major Despite invariable fractions, both peak rates decreased (30 20%, correspondingly) concomitant increase mean times, resulting five- twofold increases late early ratios, correspondingly. Diastolic asynchrony increased (from 4.7 +/- 2.0 6.4 3.2 from 2nd 7th decade). The should allow detection LV
