The normal values of left and right ventricle differ. Due to the high pressures which must be generated by the LV, the isovolumic times of the LV are relatively long. The RV generates less pressure and therefore the index also lower with average at around 0.28. A Tei index above 0.55 (TDI) is considered abnormal. | The normal values of left and right ventricle differ.
