Enhanced Cardiac Arrythmia Origin Detection System

An improved system for identifying the origin of cardiac arrythmias, providing more accurate and efficient detection through advanced mapping and localization techniques.

The original patent, 'Finding the origin of an arrythmia', presented a method for analyzing results of a cardiac invasive procedure to locate the origin of a cardiac arrythmia. However, this method has limitations, such as potential inaccuracies in calculating local activation times (LATs) and difficulties in determining the origin of the arrythmia. The new inventive concept addresses these limitations by introducing advanced mapping and localization techniques, enabling more accurate and efficient detection of the arrythmia origin.

The Enhanced Cardiac Arrythmia Origin Detection System comprises a probe insertable into a heart chamber, equipped with at least two pairs of electrodes and a location sensor. A processing unit generates a 3D map of the heart chamber, calculates LATs and LAT-derived distances at multiple points on the surface, and determines the origin of the arrythmia based on the intersection of multiple loci of possible origin positions. The system also features a display unit to visualize the 3D map with the origin highlighted, facilitating real-time tracking and adjustment of the probe's position for ablation. Additionally, the system can automatically adjust the probe's position to facilitate ablation at the detected origin.

The new inventive concept introduces several novel features, including the use of a 3D map, real-time LAT calculation, and automated probe adjustment. These advancements provide a more accurate and efficient method for detecting the origin of cardiac arrythmias, overcoming the limitations of the original patent.

Alternative embodiments of the Enhanced Cardiac Arrythmia Origin Detection System could include using different types of sensors or probes, incorporating additional data sources, such as ECG or MRI, or developing miniaturized versions for use in smaller heart chambers. Variations could also include adapting the system for use in other medical procedures or applications.

The Enhanced Cardiac Arrythmia Origin Detection System has significant commercial potential in the medical device industry, particularly in the fields of cardiology and electrophysiology. The system could be marketed to hospitals, clinics, and medical research institutions, offering a more accurate and efficient solution for detecting and treating cardiac arrythmias.
