AI Technical Summary

Technical Problem

Existing implantable diagnostic and treatment systems rely primarily on cardiac electrical signals for decision-making, leading to false positives and inappropriate treatments due to the lack of integration with other data sources, such as hemodynamic status.

Method used

The system incorporates multiple sensors, including pressure sensors placed in the anterior mediastinal space and electrical sensors to detect cardiac signals, which are processed to generate pressure curves and correlate them with cardiac electrical data to assess the patient's physiological status accurately.

Benefits of technology

This approach reduces false positives and improves the specificity of treatment decisions by integrating cardiac electrical and mechanical signal data, thereby minimizing inappropriate shocks and enhancing patient safety.

Abstract

A method for assessing a physiological status of a patient is described herein. The method includes placing at least one pressure sensor in an anterior mediastinal space of the patient. Pressure signal data received from the at least one pressure sensor is amplified and filtered to separate the pressure signal data into different frequency bands. A set of pressure curves is generated based on the separated pressure signals in different frequency bands, and a physiological status of the patient is assessed based at least in part on the set of pressure curves.
