The accuracy of models of cardiac anatomy obtained using endocardial mapping and models supplemented with contrast-enhanced computed tomography (CT) data was assessed for catheter ablation in patients with supraventricular arrhythmias. A comparative analysis of the geometric characteristics of the models, including the location and orientation of the pulmonary vein ostia, was performed using quantitative and qualitative metrics. The results showed that integration of CT data supports more accurate reproduction of atrial anatomy, improving navigation and increasing the effectiveness of radio-frequency ablation and cryoablation. The approach proposed here can be recommended for widespread clinical use to improve the accuracy and safety of interventional procedures.
This report presents a description of a physiotherapy apparatus in which the therapeutic factor is a low-frequency pulse-modulated alternating current of adjustable amplitude and frequency. The results of testing the device are presented—it was used for preparation for competitions and for the treatment and rehabilitation of injuries in professional athletes. The potential for using the apparatus in wide clinical practice is considered.
The relevance of cardiovascular research is determined by World Health Organization data indicating that cardiovascular diseases are currently among the leading causes of death worldwide. The development of mobile diagnostic devices, which are part of the modern workflow of the practicing physician (general practitioner, cardiologist), is therefore required. These devices support faster diagnosis without the need for in-office examination.
This study aimed to evaluate the effectiveness of the Real Go controller, which uses walking on the spot, in preventing the development of symptoms of simulator sickness (SS), as compared with traditional joysticks. A total of 30 subjects (aged 15–25 years) took part in the experiment and were randomly assigned to two groups. The results showed a statistically significant reduction in symptoms of SS in the Real Go group (p = 0.022), along with an inverse correlation between virtual reality (VR) experience and symptom severity (Rs = −0.57; p = 0.001). The data obtained here confirm the potential of using natural movement methods in VR to improve user comfort.
This report presents approaches to the development of a robotic system for the rehabilitation of patients with neuromotor disorders of the musculoskeletal system. A method for determining the target trajectory of a wrist point during Nordic walking with poles is proposed for the subsequent development of algorithms for controlling the movement of a robotic exoskeleton and for gait analysis and correction of the movement performed.
