SYSTEMS AND METHODS FOR USING LEADLESS PACEMAKER TO ASSIST NON-VASCULAR IMPLANTABLE CARDIAC DEFIBRILLATOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240042220 titled 'SYSTEMS AND METHODS FOR USING LEADLESS PACEMAKER TO ASSIST NON-VASCULAR IMPLANTABLE CARDIAC DEFIBRILLATOR

Simplified Explanation

The abstract describes a system that detects arrhythmic episodes and performs arrhythmia discrimination. The system includes a leadless pacemaker (LP) that senses a near-field electrogram (NF-EGM) and a non-vascular implantable cardioverter defibrillator (NV-ICD) that senses a far-field electrogram (FF-EGM). The LP determines cardiac activity information based on the NF-EGM and optionally paced cardiac events caused by the LP. The LP sends i2i messages including the cardiac activity information to the NV-ICD when specific pacemaker conditions are detected. The NV-ICD can detect arrhythmic episodes and perform arrhythmia discrimination based on the cardiac activity information.

  • Leadless pacemaker (LP) senses near-field electrogram (NF-EGM).
  • Non-vascular implantable cardioverter defibrillator (NV-ICD) senses far-field electrogram (FF-EGM).
  • LP determines cardiac activity information based on NF-EGM and optionally paced cardiac events.
  • LP sends i2i messages with cardiac activity information to NV-ICD when specific pacemaker conditions are detected.
  • NV-ICD can detect arrhythmic episodes and perform arrhythmia discrimination based on the cardiac activity information.

Potential Applications:

  • Cardiac monitoring and arrhythmia detection in patients with pacemakers and defibrillators.
  • Improved management of arrhythmic episodes and discrimination of different types of arrhythmias.

Problems Solved:

  • Detection of arrhythmic episodes in patients with pacemakers and defibrillators.
  • Discrimination between different types of arrhythmias for appropriate treatment.

Benefits:

  • Enhanced monitoring and detection of arrhythmic episodes.
  • Improved accuracy in discriminating different types of arrhythmias.
  • Better management and treatment of arrhythmias in patients with pacemakers and defibrillators.


Original Abstract Submitted

methods, systems, and devices that detect arrhythmic episodes and perform arrhythmia discrimination are described. such a system includes a leadless pacemaker (lp) that senses a near-field electrogram (nf-egm), and a non-vascular implantable cardioverter defibrillator (nv-icd) that senses a far-field electrogram (ff-egm). the lp determines cardiac activity information based on the nf-egm and optionally also based on paced cardiac events caused by the lp. the lp monitors for specific pacemaker condition(s), sends i2i message(s) including the cardiac activity information to the nv-icd when at least one of the specific pacemaker condition(s) is detected by the lp, and does not send i2i message(s) including the cardiac activity information to the nv-icd when the lp detects none of the specific pacemaker condition(s) after the nv-icd receives the i2i message(s) transmitted by the lp, the nv-icd can detect an arrhythmic episode and/or perform arrhythmia discrimination based on the cardiac activity information included therein.
