Cardiac electrical mapping system is a powerful tool for studying the electrical properties of multicellular cardiac preparations. The system is designed to simultaneously record electric activities and conductive information including the initiation sites and frequency of action potentials, direction and velocity of conduction, electrical conduction dispersion, repolarization dispersion and QT interval dispersion from in vitro, in vivo and ex vivo experimental samples. It is also compatible to monitor ventricular systolic pressure, coronary perfusion pressure, monophasic action potentials, myocardial tension, perfusion temperature if 6 or 16 more channels are added onto this system. Accurately find abnormalities of sodium, potassium and calcium currents through behaviors of depolarization and repolarization at tissue levels and help researchers to understand mechanism of cardiac arrhythmias such as atrial fibrillation and ventricular fibrillation. Efficiently test effects of a new drug on cardiac parameters and assess cardiotoxicity. Screen anti-arrhythmic effects for novel medicines.
