Smart cards widely used as access tags or to carry a patient’s medical information, can switch off critical care equipment. The cards use a radio frequency identification (RFID) system which, when ...

Substrate-based mapping for ventricular tachycardia (VT) ablation is hampered by its inability to determine critical sites of the VT circuit. We hypothesized that those potentials, which delay with a ...

The field of invasive cardiac electrophysiology (EP) has witnessed extraordinary advancements over the past 57 years, beginning with the foundational recording of the His bundle electrogram in 1969 by ...

Mapping is the term used to describe the process of creating a 3D model of a cardiac chamber to guide the delivery of ablation therapy. The initial model is anatomical, outlining the endocardial ...

Catheter ablation is an important treatment modality for patients with atrial fibrillation (AF). Although the superiority of catheter ablation over antiarrhythmic drug therapy has been demonstrated in ...

Atrial fibrillation (AF) is a significant cause of inappropriate implantable cardioverter defibrillator (ICD) shocks. A male patient in his 70s was diagnosed with Brugada syndrome (BrS) in his 40s ...

Abstract A new graphical tool for measuring the time constancy of dynamical systems is presented and illustrated with typical examples.
