Key result
High-resolution, log-scale continuous wavelet transforms reveal underlying structural patterns within ventricular fibrillation ECG waveforms.
An energy-based continuous wavelet transform method enables visualization of underlying structures in ventricular fibrillation ECG signals.
Wavelet analysis may visualize hidden VF patterns; leaves open any clinical role and requires validation before practice change.
Recent work has attempted to utilize wavelet techniques in the analysis of biomedical signals including ECGs. Here, the authors present an energy-based method of interrogating the ECG in VF using high-resolution, log-scale continuous wavelet plots. With this method, underlying structures within the VF waveform are made visible in the wavelet time-scale half space.
