title: [The development of a 64-channel epicardial potential mapping system].
abstract: A 64-channel epicardial potential mapping system was developed in order to study the mechanics of arrhythmia such as atrial fibrillation and ventricular fibrillation, and instruct the procedure of detecting and eliminating abnormal rhythm in experiment or clinic. The system was consist of electrode, amplifier, A/D card, computer and output device. The system's software include signal acquisition module, signal preprocessing module, character-point detecting module, isochrone-map construction module, output display and print module. The system could be used to detect the activation path of atrial fibrillation and ventricular fibrillation.
