[Heart rate variability in the prognosis of tilt-testing results].

Study aim was assessment of dynamics of spectral parameters of heart rate variability (HRV) during the Westminster and Italian protocols of tilt-test (TT). We included in this study 114 patients with recurrent vasovagal syncope (VVS). Basing on TT results we distinguished 4 groups of patients: with positive result of the Westminster protocol (WPTT) (group 1, n=30); with negative result of WPTT (group 2, n=23); with positive result of the Italian protocol (IPTT) (group 3, n=44); with negative result of IPTT (group 4, n=11).

[Assessment of vasovagal origin of syncope based on history features].

Study aim was to elaborate questionnaire for diagnostics of vasovagal syncope (VVS) based on data of anamnesis. We examined 182 patients (mean age 37.1+/-14.

[Clinical features and history of vasovagal syncope].

Aim of this investigation was to study special characteristics of natural course of vasovagal syncope (VVS). During 3 years we examined 212 patients (44% men) in accordance with recommendations of European Society of Cardiology using tilt tests according to Westminster or Italian protocols for confirmation of vasovagal genesis. Depending on results of initial investigation patients were divided into 2 groups: group 1 comprised 144 patients (68%) satisfying criteria of VVS; group 2 comprised other patients (n=41, 19%) with transitory loss of consciousness of unclear origin.

Can the result of a tilt test be predicted in the first five minutes?

Background: Head-up tilt testing (HUT) plays a pivotal role in the management of vasovagal syncope (VVS). Heart rate variability (HRV) is a well-known method used for noninvasive evaluation of autonomic nervous system activity. However, different results have been obtained in studies that have evaluated the HRV response to HUT in patients with VVS.

[Wall motion abnormalities and hemodynamic parameters in patients with left bundle branch block during exercise echocardiography].

Study aim was to investigate dynamics of local contractility and hemodynamic parameters during exercise stress echocardiography (EEcho) in patients with left bundle branch block (LBBB). We examined 23 patients (15 men, 8 women) aged 48-65 years (mean age 53.9+/-8.

[Frequency of detection the of Brugada syndrome signs in the course of ECG registration].

The aim of the study was to assess prevalence of the Brugada syndrome during carrying out ECG in the conditions of medico-sanitary division of a large industrial enterprise. Signs of the Brugada syndrome were found on 20 of 42779 ECGs (0.047%) registered during 1 year in patients aged 22-68 years.

[Diagnosis of coronary atherosclerosis using echocardiography with bicycle ergometry exercise].

Aim: To determine sensitivity and specificity of stress echocardiography (SEC) in diagnosis of stenosing atherosclerosis of coronary arteries (CA), especially in patients recovered from Q-myocardial infarction.

Material And Methods: The above sensitivity and specificity were studied in 75 patients (70 males and 5 females; mean age 53.7 +/- 7 years) with coronary atherosclerosis (CS).

[Prognostication of the course of stable ischemic heart disease by exercise stress echocardiography].

We analyzed data from 549 patients (450 with high and 99 -- low pretest probability of ischemic events). Duration of observation was 12-42 (mean 20.1+/-11.
