Abstract:
This paper applied the Shannon Entropy based on the cross correlation to analyze the epicardial signals from anterior wal of the canine atria. The result demonstrated that during sinus rhythm, the stability level of the correlation among signals from anterior right atria is much higher than the signals from anterior left atria. Al the signals from the anterior wal descended when the rhythm changed from sinus rhythm to atrial fibril ation(AF). However, there were some regions stil having a stable correlation during AF. The results wil be helpful to enhance understanding of the correlation characteristic of AF.
