Abstract :
Some recently researches have showed that cardiac electrical activities are chaotic during ventricular fibrillation (VF). It is very difficult to realize the originations and evolvements of these complex activities by used of non-simultaneous mapping techniques. Simultaneous multiple sites epicardial mapping is one of the precise mapping techniques developed in recent years. Fudan University has designed a novel 64/176-channel epicardial mapping system, The new design includes a multi-electrodes patch, 64-channel ECG (electrocardiogram) signal amplifier, 80-channel A/D converter and a PC (personal computer). It uses finite hardware resources to detect depolarization wave from any way, any direction wherever in the whole mapping area. In this article we will discuss the characteristics of the mapping system and some interesting results we have obtained from the animal trials by use of this system
