We analyzed results of 24-hour ECG monitoring of 238 patients with PLVA. The main group was divided into 3 subgroups depending on the treatment approach: patients who were treated with optimal background therapy (OBT), percutaneous coronary interventions (PCI), coronary artery bypass graft (CABG) surgery. All patients underwent 24-hours standard ECG monitoring.</p><p><strong>Results</strong>. Our research showed that 50.0% of patients of the first group had tachycardia. AV-junction conduction problems often were observed in those persons (PQ interval was 179.7±8.4 ms, which was significantly higher than in the control group, 149.3±5.4 ms, р&lt;0.05). The longest QT interval was also stated for the first group, 532.4±27.3 ms, which was significantly longer than the average values of the control group (438.7±24.6 ms) and the second group (460.2±20.5 ms) respectively, р&lt;0.05. Revascularization procedures (in the second and third groups) allowed achieving heart rate (HR) control in 66.1% and 62.5% of patients respectively. Complete right bundle branch block (CRBBB) was the most frequent phenomenon of patients of the third group (47.9%), which was significantly higher than in the patients of the first and control groups. We also detected a high frequency of supraventricular ectopic complexes in patients of the first and the third groups. A percentage of ventricular ectopic beats was the highest in the third group (17.7%).</p><p><strong>Conclusions</strong>. Patients with PLVA tended to have tachycardia, but the use of LV revascularization procedures allowed improvement of heart rate control. The patients were also characterized by a high percentage of impulse conduction in the atria, “AV-junction” and His bundle branches and the use of LV revascularization procedures did not improve the mentioned phenomena, and increased the risk of ectopic complexes in some cases (after CABG).</p><p>Patients with PLVA had significantly prolonged “QT-interval” and therefore (along with the frequent disorders of repolarization) increased risk of sudden death. However, the use of LV revascularization (PCI) reduced it significantly.</p&gt;}, number={4}, journal={Galician Medical Journal}, author={Chinyerenwa, Okara and Vakaliuk, Igor P. and Libryk, Oleg M.}, year={2016}, month={Nov.}, pages={E201643} }
