title: [Association between QT-interval and its dispersion with factors determining prognosis of cardiovascular morbidity and mortality].
abstract: OBJECTIVE
  To elucidate relation between prolongation of corrected maximal QT intervals and QT dispersion (QTcmax, QTcD) and presence and severity of arterial hypertension, as well as other factors determining high cardiovascular risk in female population of Tallinn aged 56 - 66 years.
  
  
  METHODS
  A sample of female citizens of Tallinn (n=123, age 56 - 65 years) were subjected to standard examination including blood pressure measurement, electrocardiography, echocardiography, and laboratory tests.
  
  
  RESULTS
  Presence of prolonged QTcmax and/or QTcD were associated with elevation of pulse pressure, which reflected strain and elasticity of the aorta, as well as with presence of left ventricular hypertrophy, especially concentric variant of changes of left ventricular geometry. Participants with prolonged QTcmax and/or QTcD had higher total 10 year risk of cardiovascular morbidity and mortality.
