Sodium leak through K2P potassium channels and cardiac arrhythmia, an emerging theme. [PDF]

, 2017
In this issue of EMBO Molecular Medicine, Decher et al (2017) identify a point mutation in the K2P2 (TREK‐1) potassium (K+) channel that changes function in just those ways expected to predispose to right ventricular outflow tract (RVOT) ventricular

Investigating the role of electroanatomical mapping in single‐shot pulsed field catheter ablation

Journal of Arrhythmia
Introduction Pulsed field ablation (PFA) is a form of nonthermal energy that has been recently introduced for pulmonary vein isolation (PVI). A multi‐electrode pentaspline catheter for delivery of PFA guided by fluoroscopy has become widely available for

Management of asymptomatic arrhythmias: a European Heart Rhythm Association (EHRA) consensus document, endorsed by the Heart Failure Association (HFA), Heart Rhythm Society (HRS), Asia Pacific Heart Rhythm Society (APHRS), Cardiac Arrhythmia Society of Southern Africa (CASSA), and Latin America Hear

Europace, 2019
Asymptomatic arrhythmias are frequently encountered in clinical practice. Although studies specifically dedicated to these asymptomatic arrhythmias are lacking, many arrhythmias still require proper diagnostic and prognostic evaluation and treatment to ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
