TI  - Left ventricular tissue Doppler imaging in normal adults with clinic BP of 
      120/80mmHg or less.
PG  - 16-21
AB  - BACKGROUND: There is only scanty data on tissue Doppler imaging (TDI) of 'normal' 
      adults. METHODS: Twenty eight asymptomatic adults (20-45 yrs) without 
      cardiovascular risk factors, clinic BP < or = 120/80mmHg and normal 
      echocardiographic examination were evaluated by tissue Doppler imaging to find 
      normal reference values in this population. RESULTS: There was significant 
      heterogeneity in TDI velocities and duration of different segments of left 
      ventricle (LV). Sa and Ea velocities were lower at medial mitral annulus and 
      middle part of interventricular septum (IVS) than at lateral mitral annulus and 
      middle part of left ventricular lateral wall. Isovolumic contraction time (IVCT) 
      was significantly less at lateral mitral annulus and mid part of lateral wall of 
      LV. Isovolumic relaxation time (IVRT) was significantly less at lateral mitral 
      annulus. Aa velocity was lower at middle part of IVS. E/Ea velocity ratio was 
      significantly lower at lateral mitral annulus. Ea/Aa velocity ratio was always 
      more than 1. Relatively higher values were recorded at lateral mitral annulus and 
      mid part of left lateral wall. Myocardial performance index values were higher at 
      mid segments than at annulus. CONCLUSION: Our data provides reference values of 
      TDI for healthy normal adults and may help in the detection of onset of early 
      diastolic dysfunction in this age group.
