Pearls and Pitfalls of Pulsed Field Ablation

Korean Circulation Journal, 2023
Pulsed field ablation (PFA) was recently rediscovered as an emerging treatment modality for the ablation of cardiac arrhythmias. Ultra-short high voltage pulses are leading to irreversible electroporation of cardiac cells subsequently resulting in cell death.

Thermal Profiles for Focal Pulsed Electric Field Ablation

JACC: Clinical Electrophysiology, 2023
Pulsed electrical field (PEF) ablation may cause tissue heating. These changes are reportedly small, but each PEF system and waveform will have a different behavior, and data are lacking.This study sought to compare the temperature profile of focal point, monopolar biphasic PEF ablation versus radiofrequency (RF).Ablation lesions were performed on ...

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.
