     【Abstract】 AIM: To establish methods of constructing animal model, recording and preprocessing synchronized discharge of inferior cardiac nerves. METHODS: Cats were used as animal model. The synchronized discharge was recorded by the physiological data acquisition system and preprocessed with Autoregressive (AR) model spectral analysis, Finite Impulse Response (FIR) digital filter and algorithm based on pooled t test. RESULTS: The discharge with obvious synchronization was obtained and four parameters to be analyzed were extracted. CONCLUSION: The animal model and recording system can accurately record the synchronized discharge of inferior cardiac nerves and the preprocessing method can precisely extract the discharge parameters of inferior cardiac nerves.
