title: [Rhythm and conductivity disorders in patients at the initial stages of metabolic syndrome].
abstract: The aim of the work was to evaluate the prevalence of cardiac rhythm and conductance disturbances in patients with early manifestations of metabolic syndrome (MS). 24-hour ECG monitoring was undertaken in 105 patients meeting AHA/NHLBI (2005) MS criteria and in 79 healthy subjects. Exclusion criteria were the presence of diabetes mellitus, CHD, and obesity (body mass index > 40 kg/m2). MS was associated with an increased number of supraventicular extrasystoles (628.9 +/- 49.5 vs 415.9 +/- 57.9, p < 0.05) and ventricular extrasystoles (34.4 +/- 9.9 vs 11.8 +/- 6.5 for paired ones and 9.5 +/- 3.7 vs 2.2 +/- 4.0 for group ones, p < 0.05), higher frequency of tachyarrhythmia (supraventicular tachycardia: 18.1 vs 7.6%, p < 0.05; atrial fibrillation: 9.5 vs 2.5, p < 0.05; sinus node arrest: 6.7 vs 0%, p < 0.05). Regression analysis revealed significant correlation between arrhythmias and the number of components of the disease. It is concluded that cause-and-effect relationship between MS and cardiac rhythm disturbances is apparent at the early stage of the disease.
