Medtronic Patent - Atrial Tachycardia Detection Based on Cardiac Rhythm Regularity
Summary
The USPTO granted Medtronic patent US12594019B2 covering systems and methods for detecting atrial tachycardia (AT) by analyzing cardiac rhythm regularity. The patent discloses techniques that apply different AT detection criteria depending on whether heart beat intervals are determined to be regular or irregular, enabling more accurate identification of AT episodes.
What changed
The USPTO issued patent grant US12594019B2 to Medtronic, Inc. for a cardiac rhythm analysis system that determines atrial tachycardia episode detection criteria based on the regularity of heartbeat intervals. The system applies a first set of detection criteria when intervals are regular and a second set when intervals are irregular, indicating AT detection upon satisfaction of at least one criterion in the applicable set.
Competitors developing cardiac monitoring or implantable rhythm management devices should evaluate whether their products may fall within the scope of these 11 claims. The patent establishes enforceable intellectual property rights in the United States that may require licensing negotiations or design modifications to avoid infringement.

Abstract
This disclosure is directed to systems and techniques for determining an evidence level of an atrial tachycardia (AT) episode based on heart beat intervals in the cardiac activity data over a pre-determined time period. Based on a determination that the evidence level indicates relatively regular heart beat intervals, the example techniques apply a first set of AT detection criteria and indicate a detection of an AT episode based on satisfaction of at least one of the first set of AT detection criteria. Based on a determination that the evidence level indicates relatively irregular heart beat intervals, the example techniques apply a second set of AT detection criteria and indicate a detection of an AT episode based on based on satisfaction of at least one of the second set of AT detection criteria.
