Computational simulations of cardiac electrophysiology provide detailed information on the
depolarization phenomena at different spatial and temporal scales. With the development of …

Epicardial ablation may be required to eliminate ventricular tachycardia (VT) in patients with
underlying structural heart disease. The decision to gain epicardial access is frequently …

Gaining an insight into atrial excitation dynamics is crucial for a thorough understanding of
the mechanisms that underlie rhythm disturbances and their appropriate treatment, eg via …

Regions with pathologically altered substrate have been identified as potential drivers for
atrial fibrillation (AF) maintenance. Recently, local impedance (LI) measurements have …

Purpose: The acute effect of radiofrequency (RF) ablation includes local necrosis and
oedema. We investigated the spatiotemporal change of atrial electrograms in the area …

Background: The use of mini electrodes with a small surface and narrow electrode-to-
electrode spacing is believed to lead to a higher electrical resolution. Until now, the effects of …

Catheter ablation is a major treatment for atrial tachycardias. Hereby, the precise monitoring
of the lesion formation is an important success factor. This book presents computational, wet …

Background Radiofrequency ablation (RFA) is a common approach to treat cardiac
arrhythmias. During this intervention, numerous strategies are applied to indirectly estimate …

Aims Pulmonary vein isolation (PVI) is a standard treatment of atrial fibrillation (AF). AF
recurrence after PVI occurs in a substantial number of cases. A novel ablation catheter …

Atrial fibrillation is a heart condition that causes an irregular and abnormally fast heart rate,
as well as a multifactorial and progressive cardiac disease with different manifestations in …
