- Values are presented as absolute values and z-scores created from published reference data
- aindicates significance according to 95% confidence interval (CI)
- LV, left ventricular wall; IVS, interventricular septum; RV, right ventricular wall; Am, peak myocardial velocity during atrial contraction; Sm, peak myocardial velocity during ventricular ejection; Em, peak myocardial velocity during rapid ventricular filling; SD, standard deviation
