Abstract:
Objective To investigate the regulation of fluctuation of beat to beat cardiac cycle.Methods A cardio-electric cycle consists of cardio-electric activity called P-T interval and cardio-electric resting TP segment,P-R interval and Q-T interval constitute P-T interval.The cardiac cycles fluctuate along with the time span fluctuation of sub waves and segments.This paper firstly extracted sub waves and segments based on signal processing methods,then discussed the contribution ratio of all waves and segments toward cardiac cycle fluctuation according to statistics.Results Experimental results indicated that the cardiac cycle fluctuation was mainly consistent with the change of TP segment.The P-T interval varied consistently with P-R interval foremost.Conclusion It is revealed that rule of cardiac cycle fluctuation is very useful for further research to figure out the cardiac function and mechanism.
