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 ...

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 ...

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 ...

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 ...

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 ...
