Abstract :
Beat-to-beat changes in P wave morphology, as well as the sensitivity of cross-correlation coefficient (CCC) and average magnitude cross differences (AMCD) in detecting these morphological variations, was studied. Effects of respiration on P wave morphology were also examined. Two bandpass filters were designed and implemented in an attempt to reduce noise and increase the sensitivities of CCC and AMCD
