Detection and analysis of cardiac waveforms

An example method includes performing amplitude-based detection to determine location of R-peaks for a plurality of electrograms. The method also includes performing wavelet-based detection to determine location of R-peaks for the plurality of electrograms. The method also includes adjusting the location of the R-peaks determined by the wavelet-based detection of R-peaks based on the location of R-peaks determined by the amplitude-based detection of R-peaks. The method also includes storing, in memory, R-peak location data to specify R-peak locations for the plurality of electrograms based onthe adjusting. 示例方法包括执行基于振幅的检测，以确定多个电描记图的R峰的位置。该方法还包括执行基于小波的检测，以确定所述多个电描记图的R峰的位置。该方法还包括基于由基于振幅对R峰的检测确定的R峰的位置来调节由基于小波对R峰的检测确定的R峰的位置。该方法还包括在存储器中存储R峰位置数据，以基于调节指定所述多个电描记图的R峰位置。
