Orthogonal bipolar approach to detect cardiac repolarization changes related to activation direction Open
Funding Acknowledgements Type of funding sources: None. Background In addition to wave propagation, tissue anisotropy is thought to determine repolarization (repol). This may explain PVC-induced vulnerability to re-entry, based on change o…

Orientation of conduction velocity vectors on cardiac mapping surfaces Open
Aims Electroanatomical maps using automated conduction velocity (CV) algorithms are now being calculated using two-dimensional (2D) mapping tools. We studied the accuracy of mapping surface 2D CV, compared to the three-dimensional (3D) vec…

Automated Identification of Ventricular Tachycardia Ablation Targets: Multicenter Validation and Workflow Characterization Open
Decrement evoked potentials (EPs) (DeEPs) constitute an accepted method to identify physiological ventricular tachycardia (VT) ablation targets without inducing VT. The feasibility of automated software (SW) in the detection of arrhythmoge…

High density intramural mapping of post‐infarct premature ventricular contractions and ventricular tachycardia Open
Background Spontaneous ventricular premature contractions (PVCs) and ventricular tachycardia (VT) in the acute post infarct milieu is assumed to be due to automaticity. However, the mechanism has not been studied with intramural mapping. O…

Acute Effects of Ibrutinib on Ventricular Arrhythmia in Spontaneously Hypertensive Rats Open
Ibrutinib-induced VA is associated with old age in SHR. Acute dysregulation of calcium and repolarization dynamics play important roles in ibrutinib-induced VF.
