Do the predictors of right ventricular pacing-induced cardiomyopathy add up?

Indian Heart Journal, 2021
Objective: Knowledge of factors causing pacing-induced cardiomyopathy (PICM) is incomplete. We sought to estimate the incidence and predisposing factors for PICM and evaluate if the risk they portend adds up.

A comparison of discrete and continuum models of cardiac electrophysiology [PDF]

, 2014
When modelling tissue-level cardiac electrophysiology, a continuum approximation to the discrete cell-level equations, known as the bidomain equations, is often used to maintain computational tractability.

Bipolar Radiofrequency Catheter Ablation for Ventricular Arrhythmias

Reviews in Cardiovascular Medicine, 2022
A minority of premature ventricular contractions (PVC) and ventricular tachycardias (VT) have an intramural origin, which represents a challenge for conventional radiofrequency ablation.

Stretchable Microelectrode Arrays for Electro‐Mechanical Probing of Brain Spheroids

Advanced Healthcare Materials, EarlyView.
A multimodal device featuring kirigami‐patterned stretchable microelectrode arrays enables concurrent mechanical actuation and electrophysiological recording of brain spheroids. The platform supports multiple loading regimes and reveals mechanically induced modulation of spontaneous network activity in 3D neural tissue models.
