Electrical Mapping – Advancing iPSC-CM Research with Microelectrode Array
by Dr Jay Lu In this post, we are presenting a comprehensive, step-by-step tutorial video on how to measure electrical activity in iPSC-CM. Please also note that Electrical Mapping System can work on various cardiac tissues, ranging from the whole heart to iPS-CM, to pinpoint the exact areas of diseased ...
The Significance of Conduction Dispersion in Cardiac Electrophysiology
by Dr Jay Lu In this blog post, we’d like to discuss conduction dispersion, a critical parameter in cardiac electrophysiology. Conduction dispersion refers variations in the time it takes for an action potential to travel through the heart muscle. More specifically, it is a measure of the inhomogeneity of conduction ...
Proarrhythmia and Action Potential Triangulation: A Quick Overview
by Dr Jay Lu In this blog, we will explore the concept of proarrhythmia, a serious adverse effect of certain medications that can disrupt the normal electrical activity of the heart and lead to life-threatening arrhythmias, such as early afterdepolarizations (EADs) and Torsade de Pointes (TdP). The normal electrical activity ...
The importance of Effective Refractory Period in Cardiac Electrophysiology
by Dr Jay Lu In this post, we’d like to discuss the effective refractory period (ERP), which is one of the most important indices in cardiac electrophysiology. ERP simply means during cardiac action potential phase 0, 1, 2, and part of phase 3, the cells is refractory to the initiation ...
Optical Mapping: Measure the changes of electrical signals in the heart(Video)
by Dr Jay Lu From our previous blog post, we discussed “the physiological significance of optical mapping” in cardiac electrophysiology. In this post, we are presenting an exciting video which demonstrates exactly how Optical Mapping System works. In essence, optical mapping uses high-speed fluorescence-based imaging with various probes for transmembrane potential ...
What You Can Do With Electrical Mapping System(Video)
by Dr Jay Lu In this mini post, we are presenting a short video which gives you an idea of what you can do with Electrical Mapping System. In short, with the help of sensitive multiple electrode arrays (MEAs) and other electrodes, you can easily record field potential, ECG, monophasic action ...
