ESTIMATION OF THE THICKNESS OF THE CARDIAC WALL BASED ON ECG RESULTS Russian patent published in 2022 - IPC A61B5/107 A61B5/367 G06N20/00 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to medical equipment, namely to a method and system for estimating the thickness of the cardiac wall. The system comprises an interface and a processor. Electrophysiological measurements made in the heart of the patient are received by means of the interface. The thickness of the wall in a predetermined area of the heart is measured by means of the processor based on the electrophysiological measurements. The thickness of tissue is therein estimated using electrophysiological measurements including the use of a trained machine learning model. Based on the results of the ablation procedure executed in the predetermined area of the heart, the model is adjusted. The ML model comprises an auto-encoder type containing an encoder connected with a decoder. The auto-encoder is configured to operate based on an intracardiac electrogram or based on a 12-lead electrocardiogram.

EFFECT: provided are a method and a system for estimating the thickness of the cardiac wall based on electrophysiological testing using machine learning, including an auto-encoder, preventing excessive ablation or damage to the adjacent tissues, such as the esophagus, possibly located behind the cardiac tissue.
