Accurate substrate characterisation may improve the evolving understanding and treatment
of cardiac arrhythmias. During substrate-based ablation techniques, wide practice variations …

Geometric Factors in Voltage Mapping Background Voltage mapping is an important tool for
characterizing proarrhythmic electrophysiological substrate, yet it is subject to geometric …

Introduction The assessment of the ventricular myocardial substrate critically depends on the
size of mapping electrodes, their orientation with respect to wavefront propagation, and …

The fundamental hypothesis of substrate mapping for scar-mediated ventricular tachycardia
is that surrogates of the isthmus can be identified and targeted with ablation during sinus …

Cardiac electrophysiology has moved a long way forward during recent decades in the
comprehension and treatment of complex cardiac arrhythmias. Contemporary …

Background Myocardial slow conduction is a cornerstone of ventricular tachycardia (VT).
Prolonged electrogram (EGM) duration is a useful surrogate parameter and manual …

The extracellular electrogram is caused by transmembrane currents that flow into
extracellular space during propagation of the electrical impulse. Electrograms are usually …
