Li et al (2023) showed Sac/Val (a angiotensin receptor-neprilysin inhibitor) susceptibility to atrial fibrillation by improving atrial remodeling in spontaneously hypertensive rats. #CardioTwitter 👇

Electrical mapping system with a microelectrode array (8x8) was used to acquire and plot epicardial isochronal activation maps. The data were then computed into activation maps & conduction velocity by EMapScope software. #arrhythmia #mapping #electrophysiology

Optical mapping system was used to measure transmembrane potential and calcium transient. Activation time, conduction velocity, rise time, dispersion, amplitude, APD and CTD were automatically calculated by OMapScope. #Cardiology #Langendorff #heart #science #research
