Quantitative assessment of ventricular far field removal techniques for clinical unipolar electrograms

Autor: Lorenz Nick Johannes, Unger Laura Anna, Luik Armin, Dössel Olaf

Publikováno v: Current Directions in Biomedical Engineering, Vol 7, Iss 2, Pp 243-246 (2021)

The incidence of atrial tachycardia steadily increases in industrial nations. During invasive electrophysiological studies, a catheter measures electrograms within the atrium to assist detailed diagnosis and treatment planning. With unipolar and bipo

High-density Mapping Reveals Short-term Reversibility of Atrial Ablation Lesions

Autor: Huhn Oliver, Pollnow Stefan, Unger Laura, Dössel Olaf, Oesterlein Tobias, Luik Armin, Schmitt Claus

Publikováno v: Current Directions in Biomedical Engineering, Vol 4, Iss 1, Pp 385-388 (2018)

Cardiac arrhythmias such as atrial fibrillation occur frequently in industrialized countries. Radiofrequency ablation (RFA) is a standard treatment if drug therapy fails. This minimally invasive surgery aims at stabilizing the heart rhythm on a perma

Assessment of local high-density mapping for the analysis of radiofrequency ablation lesions in the left atrium

Autor: Stritt Michael, Oesterlein Tobias, Pollnow Stefan, Luik Armin, Schmitt Claus, Dössel Olaf

Publikováno v: Current Directions in Biomedical Engineering, Vol 3, Iss 2, Pp 109-112 (2017)

Recent studies about the development of endocardial radiofrequency (RF) ablation lesions (ALs) tried to identify reliable electrogram (EGM) markers for assessment of lesion transmurality. Additional clinically relevant information for physicians can

Automatic detection and mapping of double potentials in intracardiac electrograms

Autor: Oesterlein Tobias, Kramlich Alexander, Lenis Gustavo, Luik Armin, Schmitt Claus, Dössel Olaf

Publikováno v: Current Directions in Biomedical Engineering, Vol 2, Iss 1, Pp 179-183 (2016)

Catheter ablation has become a very efficient strategy to terminate sustained cardiac arrhythmias like atrial flutter (AFlut). Identification of the optimal ablation spot, however, often proves difficult when scar from previous ablations is present.

Preprocessing of unipolar signals acquired by a novel intracardiac mapping system

Autor: Huck Salina, Oesterlein Tobias, Luik Armin, Schmitt Claus, Wakili Reza, Dössel Olaf

Publikováno v: Current Directions in Biomedical Engineering, Vol 2, Iss 1, Pp 259-262 (2016)

The novel high-density mapping system RhythmiaTM Medical (Boston Scientific, Marlborough, USA) allows a fast and automatic acquisition of intracardiac electrograms (EGMs). For recording the ORION mini-basket catheter is used. Due to the small electro

Locating regions of arrhythmogenic substrate by analyzing the duration of triggered atrial activities

Autor: Verma Bhawna, Oesterlein Tobias, Luik Armin, Schmitt Claus, Dössel Olaf

Publikováno v: Current Directions in Biomedical Engineering, Vol 1, Iss 1, Pp 50-53 (2015)

Catheter ablation is the most widely used minimum invasive technique to cure atrial arrhythmias. However, the success rate of the treatment is still moderate and depends on the experience and expertise of the physicians. The aim of this work is to pr
