@article{Vatseba_2015, title={Electrolyte Imbalance in Cardiology Practice}, volume={22}, url={https://ifnmujournal.com/gmj/article/view/462}, abstractNote={<p><strong>The objective</strong> of the research was to establish the dynamics of electrolyte balance, pyruvate and lactate in patients with arterial hypertension (AH), long QT syndrome and heart rate turbulence.</p><p><strong>Materials and methods</strong>. The study included 60 patients with stage II AH. All patients were divided into three groups: Group I included 20 patients with stage II AH and normal myocardial electrical stability; Group II included 20 patients with stage II AH and long QT syndrome (LQTS); Group III comprised 20 patients with stage II AH and heart rate turbulence (HRT). The control group included 20 practically healthy persons. The parameters of heart rate turbulence, QT-interval duration, potassium, magnesium, calcium, lactate and pyruvate levels were determined.</p><p><strong>Results.</strong> A total calcium level in patients of Groups II and III increased by 27.14% (p&lt;0.001) and 29.41% (p&lt;0.001) compared to Group I, and ionized calcium level increased by 27.14% (p&lt;0.001) and 27.65% (p&lt;0.001), respectively. The level of potassium in Groups II and III was 20.63% (p&lt;0.001) and 19.59% (p&lt;0.001) lower than in Group I, and magnesium level was 14.51% (p&lt;0.001) and 12.69% (p&lt;0.001) lower compared to Group I. The level of pyruvate in Group II decreased by 60.53% (p&lt;0.001), and in Group III it decreased by 54.84% (p&lt;0.001). The level of lactate increased by 27.01% (p&lt;0.001) and 25.24% (p&lt;0.001), respectively.</p><p><strong>Conclusions.</strong> Considering the obtained results, deeper investigation of the role of electrolyte balance in the pathogenesis of arterial hypertension and myocardial electrical instability should be continued.</p><p> </p&gt;}, number={4}, journal={Galician Medical Journal}, author={Vatseba, M.
