Supraventricular Tachycardias

Abstract Background Supraventricular tachycardias (SVTs) are common in the first year of life and may be life-threatening. Acute cardioversion is usually effective, with both pharmacological and non-pharmacological procedures. However, as yet no international consensus exists concerning the best drug required for a stable conversion to sinus rhythm (maintenance treatment). Our study intends to describe the experience of a single centre with maintenance drug treatment of both re-entry and automatic SVTs in the first year of life. Methods From March 1995 to April 2019, 55 patients under one year of age with SVT were observed in our Centre. The SVTs were divided into two groups: 45 re-entry and 10 automatic tachycardias. As regards maintenance therapy, in re-entry tachycardias, we chose to start with oral flecainide and in case of relapses switched to combined treatment with beta-blockers or digoxin. In automatic tachycardias we first administered a beta-blocker, later combined with flecainide or amiodarone when ineffective. Results The patients’ median follow-up time was 35 months. In re-entry tachycardias, flecainide was effective as monotherapy in 23/45 patients (51.1%) and in 20/45 patients (44.4%) in combination with nadolol, sotalol or digoxin (overall 95.5%). In automatic tachycardias, a beta-blocker alone was effective in 3/10 patients (30.0%), however, the best results were obtained when combined with flecainide: overall 9/10 (90%). Conclusions In this retrospective study on pharmacological treatment of SVTs under 1 year of age the combination of flecainide and beta-blockers was highly effective in long-term maintenance of sinus rhythm in both re-entry and automatic tachycardias.

The goal is to establish the frequency of supraventricular tachycardias in children of the Republic of Belarus, to determine the structure and characteristics of these rhythm disturbances. An in-depth study of the properties of the conduction system of the heart was carried out by performing in the course of the esophageal electrophysiological study 108 children. A more rare detection of SVT in children in the neonatal period, in the first year of life and maximum detection at the age of 17 years, a comparatively rare finding (11.8 %) of concomitant pathology in children with SVT.

Aim. To study the association of single nucleotide polymorphism rs556621 (G> T) with development of stroke in patients of the East Siberian population with cardiovascular pathology and risk factors.Material and methods. The study involved 260 patients (157 men and 103 women) with stroke (mean age 57.0 [51.0-62.0]) and 272 patients (170 men and 102 women) of the control group (mean age 55.0 [51.0-62.0]). The examination of the main group included: collection of complaints, anamnesis, clinical examination, computed tomography of the brain, electrocardiography, echocardioscopy, ultrasound duplex scanning of extracranial brachiocephalic arteries, daily blood pressure and heart rate monitoring, analysis of the blood coagulation system. The patients of the main group have arterial hypertension, paroxysmal supraventricular tachycardias, dyslipidemia, atherosclerosis of the brachiocephalic arteries, disorders of the hemostatic system. The control group was studied in the framework of the HAPIEE international project. Molecular genetic research was performed by real-time polymerase chain reaction.Results. There were no statistically significant differences in the frequencies of genotypes and single nucleotide polymorphism rs556621 alleles (G>T) in the subgroup of patients with stroke and those in the control group. The frequency of the rare TT genotype among patients with stroke was 13.3%±4.16, among healthy individuals – 8.8±3.37% (p=0.1). Gender differences when comparing the frequencies of genotypes and alleles were also not detected (p>0.05). The frequencies of the TT genotype were approximately the same in the subgroup of patients with arterial hypertension (13.1%±4.22) and in the control group (7.4±5.25%; p>0.05). No significant differences were observed in the frequencies of the rare genotype of the studied polymorphism in the subgroup of patients with supraventricular tachycardias (20.0±14.37%), hypercoagulability (15.9±7.64%) and the control group (8.8±3.37%), p>0.05. A statistically significant relationship was found between the rare genotype TT of single nucleotide polymorphism rs556621 (G>T) and the development of stroke in patients with dyslipidemia and atherosclerotic lesions of the coronary arteries (p=0.041; odds ratio 1.86, 95% confidence interval 1.02-3.41).Conclusion. The genotype of TTs of single nucleotide polymorphism rs556621 (G> T) increases the risk of developing stroke in patients with dyslipidemia and atherosclerosis of the brachiocephalic arteries compared with carriers of the GG and GT genotypes. The obtained data are recommended to be considered when prescribing lipid-lowering and antithrombotic therapy.
