The aim of present study is analyze the relationships other marker of sympatho-vagal balance Ca/K Plasma Ratio with parameters of HRV. <strong>Methods. </strong>In basal conditions in twentee volunteers – ten women add ten men aged 33-76 years with diathesis urica recorded Heart Rate Vatiability (HRV) (“Cardiolab+VSR”, KhAI Medica, Ukraine). In blood plasma measured the concentration of Calcium and Potassium. <strong>Results. </strong>No correlation ascertained between Ca/K Plasma Ratio and LF/HF Ratio (r=-0,07) and LFnu (r=0,09). However, Ca/K Plasma Ratio moderately negatively correlated with vagal markers: SDNN (r=-0,30), RMSSD (r=-0,34), pNN<sub>50</sub> (r=-0,36), HRV TI (r=-0,34), absolute PS HF (r=-0,33) and positively with sympathetic marker Amplitude of Moda (r=0,24 for actual values and 0,38 for portion of age norm) as well as with relative PS ULF (r=0,39). The strongest correlations of Ca/K Plasma Ratio proved with absolute PS LF (r=-0,45) and variational sweep: r=-0,42 for actual values and -0,49 for portion of age norm. Canonical correlation between Ca/K Plasma Ratio, on the one hand, and the parameters of HRV, on the other hand, is strong: R=0,713; R<sup>2</sup>=0,509; Adjusted R<sup>2</sup>=0,437; F<sub>(5,3)</sub>=7,0; χ<sup>2</sup><sub>(5)</sub>=25,2; p=10<sup>-4</sup>. <strong>Conclusion. </strong>Ca/K Plasma Ratio reflects inversely vagal tone and less direct sympathetic tone, therefore is really marker of sympatho-vagal balance.</p> <p> </p> <p><strong>Keywords: </strong>Ca/K Plasma Ratio, HRV, correlations.</p>
