FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine, namely to the system and method for radiofrequency ablation and electrophysiological examination of the heart. The system contains an expandable distal end of the catheter, a processor. The distal end of the catheter has electrodes. The electrodes are made with the possibility of applying ablative energy to the tissue and being used as indicator electrodes to determine the specified criteria. The electrodes are also designed to be placed in contact with the organ tissue. The processor is designed with the ability to determine during the application of ablative energy whether the physical contact of the electrode corresponds to a predetermined contact quality. When implementing the method, the distal end of the catheter is placed in contact with the organ tissue. Ablative energy is applied to the electrodes. During the application of ablative energy, it is determined whether the physical contact of the electrode corresponds to a predetermined contact quality. In this case, the quality of the contact is assessed by evaluating a preset temperature criterion. At the same time, if the physical contact of one of the electrodes with the tissue does not correspond to a predetermined contact quality, this electrode is switched to the indicator electrode mode for electrophysiological examination.
EFFECT: due to the design features of the system, namely electrodes that can switch to ablation or electrophysiological examination modes depending on the quality of contact with the tissue measured using a temperature criterion, safer and more effective performance of balloon ablation treatment procedures is provided, which improves the clinical result of medical procedures.
