Multielectrode arrays can be used to investigate electric activity (field potential duration, conduction velocity, arrhythmic substrates, etc.) in cardiac tissue and cells. Useful to investigate the effect of diseases and drugs. 🧪

Calcium transient imaging using an @ionoptix.bsky.social setup. On the bottom of the screen we can the pretty cardiomyocyte "beating". 🧪

Calcium imaging in cardiomyocytes is a method used to measure intracellular calcium levels and assess calcium dynamics. It is a powerful tool for investigating the effects of diseases and drugs on cardiac electrophysiology and contraction, providing insights into the mechanisms of arrhythmias.
