[Heart rate and QT-interval dispersion with consideration of left ventricular geometry in a population study of men and women aged 35-59 years].

Interrelationships between heart rate (HR), parameters of QT interval dispersion on resting ECG and four variants of echocardiographically defined left ventricular geometry were elucidated in 723 participants of a population study of inhabitants of Tallinn aged 35-59 years. Examination included anthropometry, blood pressure (BP) measurement, registration of ECG and echocardiography. None of normotensive examinees had concentric left ventricular hypertrophy.

[Left ventricular geometry in inhabitants of Tallinn (an echocardiographic population study)].

Echocardiography was performed in 325 men and 398 women in the framework of a population survey of inhabitants of Tallinn aged 35 to 59 years in 1999-2001. Left ventricular geometry was analyzed according to generally recognized four types. Prevalence of concentric hypertrophy was similar in men and women (7.

Echocardiographic assessment of the different left ventricular geometric patterns in middle-aged men and women in Tallinn.

The aim of this study was to determine the association of left ventricular (LV) geometry with sex, age, arterial hypertension and obesity in Tallinn. In a framework of a population study for cardiovascular risk factors, echocardiography was carried out in 325 men and 398 women (69.3% of all 1043 participants aged 35-59) in 1999-2001.

[QT interval dispersion and hypertension in different variants of left ventricular geometry (population study)].

Aim: To assess relationship between QT dispersion, hypertension, and different variants of left ventricular geometry (concentric or eccentric hypertrophy, concentric remodeling).

Material And 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.

Blood pressure and contributing factors in inhabitants of Estonia: 15-year trends.

Aim: To study the 15-year trends of blood pressure (BP) values in inhabitants of Estonia, three independent random samples of the population of Tallinn aged 20-54 years were examined in 1984/86, 1992/94 and in 1999/2001.

Results: A substantial decrease in BP values was observed in the population of Tallinn by the early 1990s; it continued to a smaller extent during the late 1990s. An improvement in some factors contributing to the development of arterial hypertension: decrease in body mass index (BMI) mean values and positive dietary changes were observed during this period.
