From: Non-contact Quantification of Jugular Venous Pulse Waveforms from Skin Displacements
Measured JV waveforms from video recordings for five cardiac cycles of subject 11. The video recordings were synchronised with ECG signals. To perform a comparison between the recordings, two time intervals were defined. The first interval was the time between the v descent of the JV waveforms and the R peak of the ECG signal (v-R), and the second one was the duration between the R peak of the ECG signal and the c peak of the JV waveforms. All the durations were normalized for one cycle duration (v to v).
