Patent ID: 7542794

Claim:
A method of analyzing paced heart beats, comprising: providing a paced ECG signal including at least one QRS depolarization region and at least one pacing spike; analyzing the at least one QRS depolarization region and the at least one pacing spike using max-min transform analysis of the ECG signal; and identifying a time position of the at least one pacing spike in the paced ECG signal based on the max-min transform analysis of the ECG signal wherein the max-min transform analysis of the ECG signal includes: a first distance value between one of the at least one pacing spikes and an R-wave of the QRS depolarization region; a second distance value between a Q-wave portion of the QRS depolarization region and the R-wave portion of the QRS depolarization region; a third distance value between the R-wave portion of the QRS depolarization region and an S-wave portion of the QRS depolarization region; and comparing the first distance value to the greater of the second and third distance values, and if the first distance value is smaller, then identifying the signal as a false paced heart beat.
