The dynamic time warping approach allows reliable measurement of temporal sub-intervals of the filling period by tracking diastasis onset and offset on a cycle-by-cycle basis.
The dynamic time warping approach provides a reliable method to track cardiac filling phases and measure temporal sub-intervals of the filling period from left ventricular volume signals.
The dynamic time warping approach is utilised to obtain a template from the left ventricular volume signal. The technique, by performing shrinking and enlarging of the temporal axes of two waveforms, indicates the best non-linear alignment between them. In this application this technique is used to track on a cycle-by-cycle basis the diastasis onset and offset thus allowing one to reliably measure temporal sub-intervals of the filling period.
Caiani et al. (Wed,) conducted a other in Cardiac filling phases assessment. Dynamic time warping approach (Warped-average template technique) was evaluated on Tracking diastasis onset and offset to measure temporal sub-intervals of the filling period. The dynamic time warping approach allows reliable measurement of temporal sub-intervals of the filling period by tracking diastasis onset and offset on a cycle-by-cycle basis.
