Background Two years after the COVID-19 pandemic, it became known that one of complications this disease is myocardial injury. Electrocardiography (ECG) and cardiac biomarkers play a vital role in early detection cardiovascular risk stratification. The study aimed to investigate value new electrocardiographic metric for detecting minor injury patients during treatment. Methods was conducted 2021. A group 26 with verified diagnosis admitted intensive care unit infectious diseases examined....

The diagnostic management of patients with chest pain remains a clinical challenge. Magnetocardiography (MCG) is noninvasive method for the recording cardiac electromagnetic signals at multiple sites above cage. Contrary to electrocardiogram (ECG) magnetic field unaltered by surrounding tissues. present study aimed analyze value an unshielded four-channel MCG detection coronary artery disease (CAD) in pain.The included 417 subjects: 177 angiographically documented CAD (stenoses > or =50%),...

The aim of this paper is to investigate the predictive value new integrated magnetocardiographic (MCG) index (CI) in diagnosis coronary artery disease (CAD) patients with suspected CAD intermediate pretest probability and uninformative results routine tests.The study was carried out Clinic Cardiology Main Military Clinical Hospital Ukraine, Kiev (clinic 1), Second Medical 'Katholisches Klinikum Essen', Germany 2).The main group (group 1) included 89 without a history myocardial infarction....

Abstract Background : The noninvasive detection of coronary artery disease (CAD) remains a clinical challenge. Magnetocardiography is completely method that permits the registration cardiac electrical activity at multiple sites in plane above chest cage without need for electrodes. In contrast to electrocardiogram (ECG) which suffers from boundary effects and variety potential artifacts (electrode placement, etc.) MCG unaffected by such impediments as magnetic field unaltered surrounding...

In the principles of organization armed struggle defense forces most developed countries world, considerable attention is paid to evaluation combat readiness military personnel. This procedure conditioned by such interconnected goals as maximum realization potential and minimization personnel losses. The purpose work determine physiological cost activities soldiers Defense Forces Ukraine with help miniature electrocardiographic hardware software complexes.In research, ultra-miniature ECG...

Background: The noninvasive detection of restenosis after percutaneous coronary intervention (PCI) remains a clinical challenge. Previous studies have shown that magnetocardiograms reveal obvious changes in patients with artery disease (CAD) and normal electrocardiogram (ECG) at rest. Hypothesis: present study aimed to evaluate the potential magnetocardiography (MCG) for electrophysiological course successful PCI. Methods: Twelve‐lead ECG unshielded four‐channel MCG (SQUID AG, Essen,...

Introduction. Telerehabilitation is a complex of rehabilitation exercises and training programs provided to the patient remotely using telecommunication computer technologies, mainly at outpatient stage treatment. must be accompanied by appropriate software. The purpose work. To give an idea high-tech platform for telerehabilitation, which being created Institute Cybernetics named after V. M. Glushkov National Academy Sciences Ukraine. Methods. Work carried out under project Research...

Magnetocardiography is an advanced technique of measuring weak magnetic fields generated during heart functioning for diagnostics huge number different cardiovascular diseases. In this paper, k-nearest neighbor algorithm applied binary classification myocardium current density distribution maps (CDDM). CDDMs from patients with negative T-peak, male and female microvessels (diffuse) abnormalities sportsmen are compared normal subjects. Number neighbors selection k-NN classifier was performed...

Magnetocardiography is non-invasive and risk-free technique allowing body-surface recording of the magnetic fields generated by electrical activity heart. In this paper, k-Nearest Neighbor algorithm applied for binary classification myocardium current density distribution maps (CDDM). Different types CDDMs from patients with ischemic heart disease are compared normal subjects. Selection number neighbors k-NN classifier was performed to optimize characteristics. Specificity, accuracy,...

Magnetocardiography is a modern method of registration the magnetic component electromagnetic field, generated by heart activity. results are useful source for diagnosis various diseases and states, but their usage still undervalued in cardiology community. In this study, two-stage classification correlation analysis using k-Nearest Neighbor (k-NN) algorithm applied binary myocardium current density distribution maps (CDDMs). Fourteen groups CDDMs from patients with different healthy...

Goal of this study is to develop an objective assessment the severity physical status wounded combatants based on ECG records using system comprehensive scoring. Cluster analysis module Data Mining (Statictica 10) was carried out identify homogeneous subgroups in patients with combat trauma composite indicators functional states cardiovascular system. Data-mining CART decision tree algorithm for these indicators. The best combination markers, including their possible discriminator limits...

Detail description of hardware and software novel pulse-meter device - 4-channel photoplethysmograph CARDIOPULS has been presented. Above is intended for noninvasive measurements optical signals recorded from the pulse wave induced by human heart. Hardware part includes 4 photometric channels, single- or 6 standard reference ECG data processing unit, electrodes, computer software. Device can perform examination patients within 10-15 minutes at lying sitting positions both in clinical...

Magnetocardiography is one of the most progressive tools for diagnosis and investigation heart diseases, such as coronary disease. Noninvasiveness, contactlessness, high sensitivity makes magnetocardiography suitable this purpose comfortable in use physician. In paper analysis myocardium current density distribution maps proposed. Current map surface area dependence on time intensity threshold obtained.

Abstract Background The prevalence of left ventricular hypertrophy (LVH) is strongly related with established cardiovascular disease (CVD) risk factors and, hence, there has been some uncertainty about its independent relevance for ischaemic heart (IHD) after taking account such factors. Purpose To examine the associations LVH prevalent and incident cases IHD adjustment CVD in a population-based study Chinese adults. Methods prospective China Kadoorie Biobank cohort was conducted general...

The aim: To evaluate the functioning of autonomic nervous system in combatants, relationship between heat rate variability (HRV) and ques¬tionnaire indicators, to improve diagnosis post-traumatic stress disorder (PTSD) effectiveness Transcendental Meditation (TM).Materials methods: 57 combatants 30 civilians, with registering ECG HRV-analysis, self-questionnaire testing.Results: combatants' group showed an increase heart rate, degree centralisation control R.
