Advanced Rhythm Discrimination for Implantable Cardioverter Defibrillators Using Electrogram Vector Timing and Correlation

Electrogram Vector Timing and Correlation. Introduction: Discrimination of ventricular and supraventricular arrhythmias remains one of the major challenges for appropriate implantable defibrillator (ICD) therapy delivery. The electrogram vector timing and correlation (VTC) algorithm was developed for such rhythm discrimination. The VTC algorithm differentiates normally conducted supraventricular beats from abnormally conducted ventricular beats by comparing the timing and correlation of rate and shock channel electrograms.
