METHOD OF TREATING VENTRICULAR HEART RHYTHM DISORDERS Russian patent published in 2025 - IPC A61N1/18 

FIELD: medical science.

SUBSTANCE: invention refers to medicine, namely to cardiology. That is followed by a ventricular myocardial ablation by a pulse field with using a catheter comprising at least one microelectrode configured to perform the irreversible electroporation of the cardiac tissue within the ablation region. Method includes the electroporation pulse packets sequential transmission by the high-voltage electric current to the endocardial surface of the ventricle, with the subsequent production of fibrous tissue in the impact area, wherein exposure to bi-phase electric current with voltage of up to 5 kV, pulses with duration of 1-10 mcs, with inter-pulse pauses of 1-10 mcs, combined into packets of 10-100 pulses, applied by 3-10 packets per focus of ventricular arrhythmia.

EFFECT: method enables performing the effective ablation of a portion of the ventricular myocardium in a single procedure and reducing a risk of developing long-term recurrence.
