VFA delivery and implantation site detection

By locating the Koch triangle region in the right atrium of the patient's heart and testing electrode placement, the inaccurate delivery of atrium-to-ventricle cardiac therapy in existing technologies was resolved, enabling precise treatment of the left ventricle and improved cardiac synchrony.

AI Technical Summary

Technical Problem

Existing technologies struggle to accurately deliver cardiac therapy from the atrium to the ventricle through the Koch triangle region in the right atrium, resulting in poor treatment outcomes.

Method used

By locating the Koch triangle region in the right atrium of the patient's heart, the electrodes of the implantable lead or device are fixed, and the position and depth of the electrodes are tested using atrial slow path potentials (ASP) to ensure accurate delivery of VfA cardiac therapy.

Benefits of technology

It enables precise treatment of the left ventricle, improves cardiac synchronicity and treatment effectiveness, and enhances cardiac output.

Abstract

This invention discloses a method comprising locating a Koch triangle region in the right atrium of a patient's heart; securing at least one electrode of an implantable lead or device from the Koch triangle region to cardiac tissue for delivery of atrium-to-ventricle (VfA) cardiac therapy; and testing the position or depth of the at least one electrode to configure the VfA cardiac therapy. Locating the target implantation area in the Koch triangle region may include detecting atrial slow path potentials (ASP) or atrial pacing outputs.
