“…Однако следует понимать, что прогрессирование беременности не всегда сопровождается специфическими электрофизиологическими изменениями в миокарде и проводящей системе сердца, которые способствуют формированию или трансформации субстрата основных конструкций аритмогенеза и повышают риск нарушения работы сердца [11]. Предикторами риска формирования сердечно-сосудистых осложне-ний у беременных являются предшествующие кардиологические происшествия: выраженная аритмия, легочная гипертензия, врожденные пороки сердца с цианозом, сердечная недостаточность, цереброваскулярные заболевания, снижение фракции выброса менее 35 % и сатурации кислорода менее 90 % [8,12].…”

The aim of the study was to identify the dominant types of rhythm disturbances in pregnant women, to discuss the features of the pathogenesis of ventricular arrhythmias during pregnancy, the relevance of pre-gravidar diagnosis, the expediency of using antiarrhythmic drugs during gestation. Basics. Proarrhythmic mechanisms of pregnancy are associated with cardiovascular, vegetative and hormonal changes. The risk factor for complications is a previous cardiological disease. Ventricular extrasystoles are the most common. The risk of pregnancy complications increases with persistent rhythm disturbances. Conclusions. Pregnancy is associated with an increased risk of arrhythmias. Patients with a burdened history are at significant risk of relapse during pregnancy. Conducting a thorough examination of women at risk at the stage of pre-pregnancy preparation will allow timely corrective treatment.

This study is aimed at analyzing the important role of deep learning-based electrocardiograph (ECG) in the efficacy evaluation of radiofrequency ablation in the treatment of tachyarrhythmia. In this study, 158 patients with rapid arrhythmia treated by radiofrequency ablation were divided into effective treatment group (142 cases) and ineffective treatment group (16 cases). ECG examination was performed on all patients, and the indicators of ECG examination were quantified by the deep learning-based convolutional neural network model. The indicators of ECG examination of the effective treatment group and the ineffective treatment group were compared. The results showed that compared with the ineffective treatment group, the end-systolic volume (ESV), end-diastolic volume (EDV), end-systolic volume index (ESVI), and end-diastolic volume index (EDVI) of the effective treatment group were significantly decreased, and the left ventricular ejection fraction (LVEF) was significantly increased ( P < 0.05 ). After radiofrequency ablation, the ventricular rate of patients in the effective treatment group was significantly lower than that of the ineffective treatment group at 12 h and 24 h after treatment ( P < 0.05 ). In addition, compared with patients in the ineffective treatment group, the QT dispersion of the ECG in the effective treatment group was significantly higher ( P < 0.05 ). The accuracy, specificity, and sensitivity of ECG in evaluating the therapeutic effect of patients with tachyarrhythmia were 86.81%, 84.29%, and 77.27%, respectively. The area under the curve was determined as 0.798 according to the receiver operating characteristic (ROC) curve of the subjects. In summary, indicators of ECG examination based on deep learning can provide auxiliary reference information for the efficacy evaluation of radiofrequency ablation in the treatment of tachyarrhythmia.
