Identification of the earliest activation area is a common task in focal tachycardia catheter ablation treatments. In these procedures the detection of the electrogram (EGM) activation onset during ...

Implantable cardioverter defibrillators (ICDs) provide real-time monitoring and immediate defibrillation for life-threatening arrhythmias. However, the intracardiac electrogram (IEGM) acquisition of ...

Morphology. Electrogram morphology should be analyzed from the all recorded channels, ideally including a far-field dipole.

Inappropriate therapy for T-wave oversensing prevented by morphology algorithm. The upper panel shows true-bipolar RV sensing electrogram, high-voltage electrogram, and Marker Channel.

Background Atrial fibrillation(AF) may be linked to increased sudden cardiac death (SCD) risk, but patients with AF are often ...
