[QT interval dispersion and hypertension in different variants of left ventricular geometry (population study)].
OBJECTIVE
To assess relationship between QT dispersion, hypertension, and different variants of left ventricular geometry (concentric or eccentric hypertrophy, concentric remodeling).


METHODS
Blood pressure measurement, electro- and echocardiography were used in the study of a random sample of Tallinn population (321 men and 396 women) aged 35-59 years. Corrected QT dispersion (QT(c)D) equal to or exceeding 70 ms was considered increased.


RESULTS
Increase of QT(c)D was associated with left ventricular hypertrophy, especially with its concentric variant. QT(c)D prolongation was significantly more frequent in subjects with hypertension.
