[Dynamics of amplitude electrocardiographic criteria of left ventricular hypertrophy in response to manual-physical effects on the cervical spine using the method of A.Yu. Shishonin].

It is known that essential arterial hypertension (EAH) leads to structural-geometric and electrophysiological remodeling and these processes, following in parallel, do not always coincide. Thus, in patients with EAH, electrocardiographic (ECG) criteria of left ventricular hypertrophy (LVH) can occur without changing the mass of the left ventricular myocardium and its geometric characteristics. At the same time, they have independent diagnostic and prognostic value.

Purpose of the study: Evaluation of the effect of manual-physical effects according to the method of A.Yu. Shishonin on the amplitude manifestations of electrophysiological myocardial remodeling in patients with EAH.

Material and methods: We examined 148 patients with EAH with high normal blood pressure (BP), or arterial hypertension of the 1st degree, who were divided into the main and control groups. The main group included 114 patients (65 women and 49 men; mean age 61.8±5.2 years) with clinical manifestations of cervical osteochondrosis, who were treated with EAG using the method of A.Yu. Shishonin, including step-by-step manual-physical correction with the formation of a stable muscle corset in the cervical spine. The control group consisted of 34 patients (18 men and 16 women; mean age 61.6±4.0 years) who did not undergo treatment. To prove the effectiveness of the technique in reducing blood pressure and affecting the ECG pattern, instrumental diagnostic techniques for assessing blood pressure using the Korotkov auscultatory method and recording ECG criteria in 12 leads, respectively, were used.

Results: All amplitude ECG criteria had significantly lower values after EAG correction using the method of A.Yu. When assessing the dynamics of the number of patients with amplitude criteria for LVH, a reliable decrease in this indicator was shown during therapy using the method of A.Yu. Shishonin: from 25.69 to 9.03% according to the Cornell criterion and from 26.39 to 8.33% according to the Sokolov-Lyon index. Considering that all patients did not have morphological signs of target organ damage, including criteria for concentric myocardial hypertrophy, the obtained results can be explained by effects at the tissue and cellular level.

Conclusions: In the process of manual-physical correction using the method of A.Yu. Shishonin, a reliable decrease in the absolute values of the total amplitude indicators of the QRS complex teeth was revealed for all analyzed ECG criteria for LVH and a decrease in the number of patients with amplitude criteria for LVH.
