Detection and analysis of cardiac waveforms

A system comprising:

• a non-transitory memory to store electrical data representing a plurality of electrograms and machine-readable instructions;
• and
• a processor to access the non-transitory memory and execute the machine-readable instructions, the instructions comprising:
• amplitude peak detection code programmed to perform amplitude-based detection to determine location of R-peaks for a plurality of electrograms;
• wavelet peak detection code programmed to perform wavelet-based detection to determine location of R-peaks for the plurality of electrograms;
• location adjustment code programmed to adjust location of the R-peaks determined by the wavelet peak detection code based on the location R-peaks determined by the amplitude peak detection code;
• and
• code programmed to store in the memory R-peak location data to specify R-peak locations for the plurality of electrograms based on the adjusting;
• and
• a display to visualize a graphical representation based on the R-peak location data.
