Electrical Mapping Systems


The Electrical Mapping Systems (EMS) are equipped with new generation Multi-Electrode Arrays (MEAs) and high-performance amplifiers. The advanced EMapping software facilitates fast recordings of field potentials from in-vitro,  in-vivo, and ex-vivo cardiac samples. The electrical activity and conductive information can be studied in great details at tissue level.

The precision of data acquisition system makes it possible to accurately detect abnormalities on ion channels. It also can be grouped with other devices such as ventricular or coronary pressure probes, monophasic action potential system (MAP), myocardial tension, perfusion temperature and the optical mapping system. These features immensely empower cardiac electrophysiological researchers to understand better about mechanisms of cardiac arrhythmias. Our system is also an ideal candidate for efficiently screening new anti-arrhythmic drugs and testing drug toxicity.

Applicable animals: Zebrafish, mice, rats, guinea pigs, rabbits, dogs, sheep, pigs, monkeys.

Applicable tissues: cardiac slices and tissues, conductive tissues including sinoatrial node, atrioventricular node, Purkinje fibers, iPSC cells as well as in-vivo and  ex-vivo heart preparations.  The system can also be used for neurologic applications: brain in-vivo , brain slices,  and also with gastrointestinal tissues and uterus with customized system.
