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.
Because of its high success rate and low morbidity, radiofrequency (RF) catheter ablation has become first line treatment for many arrhythmias. In this procedure, one or more electrode catheters are ...
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.
Intracardiac electrogram t‐wave alternans/variability increases before spontaneous ventricular tachyarrhythmias in implantable cardioverter‐defibrillator patients: a prospective, multi‐center study.
