Bradycardia in Patients with Subcutaneous Implantable Defibrillators—An Overestimated Problem? Experience from a Large Tertiary Centre and a Review of the Literature

Reviews in Cardiovascular Medicine, 2022
Background: The subcutaneous ICD (S-ICD) has developed as a valuable alternative to transvenous implantable cardioverter defibrillator (ICD) systems. However there are certain peculiarities which are immanent to the S-ICD and may limit its use.

Challenges and opportunities for large-scale electrophysiology with Neuropixels probes

Current Opinion in Neurobiology, 2018
Electrophysiological methods are the gold standard in neuroscience because they reveal the activity of individual neurons at high temporal resolution and in arbitrary brain locations. Microelectrode arrays based on complementary metal-oxide semiconductor

Calibration of ionic and cellular cardiac electrophysiology models

Wiley Interdisciplinary Reviews: Systems Biology and Medicine, 2020
Cardiac electrophysiology models are among the most mature and well‐studied mathematical models of biological systems. This maturity is bringing new challenges as models are being used increasingly to make quantitative rather than qualitative predictions.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Conformable Ferrimagnetic Tattoo Electrodes for Plant Electrophysiology

Advanced Materials Technologies, EarlyView.
The newly developed ferrimagnetic tattoo electrode is capable of measuring plant electrophysiological activity outside the Faraday cage. Its ability to adhere without damaging the plant tissue allows long‐term recordings. This premise opens new avenues for in‐field monitoring of plant health through electrophysiology.

Very high power short duration as re-ablation strategy for recurrent atrial fibrillation

BMC Cardiovascular Disorders
Background After initially successful pulmonary vein isolation (PVI), some patients experience recurrence of AF requiring repeat catheter ablation. Radiofrequency ablation (RFA) is then mostly performed with low power long duration settings (LPLD), while
