Key result
The multiscale morphological derivative (MMD) detector reliably identified ECG characteristic waves, achieving 100% sensitivity for QRS onset and offset with standard deviations within CSE committee limits, generally outperforming threshold- and wavelet-based methods.
The MMD transform-based detector offers a promising automated method for accurate ECG signal analysis and arrhythmia recognition.

May aid automated ECG arrhythmia analysis; leaves open clinical validation in diverse cohorts before adoption.
Sun et al. (2005) studied Electrocardiogram (ECG) signal analysis. Multiscale morphological derivative (MMD) transform-based detector vs. Threshold-based detector (TD) and Wavelet-based detector (WD) was evaluated on Detection sensitivity, mean error, and standard deviation of ECG characteristic wave boundaries (QRS complex, P wave, T wave). The multiscale morphological derivative (MMD) detector reliably identified ECG characteristic waves, achieving 100% sensitivity for QRS onset and offset with standard deviations within CSE committee limits, generally outperforming threshold- and wavelet-based methods.
