DWL USA Inc transcranial doppler ultrasound doppler box
A flow chart depicting the study protocol of the 1000 Hz recordings being downsampled from their original 1000 Hz waveform to frequencies ranging from 20 to 500 Hz. A participant is shown wearing the equipment used to assess cardiac electrical activity via a 3-lead electrocardiogram (ECG) and pulsatile waveforms via <t>transcranial</t> Doppler <t>ultrasound</t> and Finapres NOVA. The 3-lead ECG captured heart rate variability (HRV) while the Doppler ultrasound and Finapres NOVA devices captured pulse rate variability (PRV). Further, the Doppler ultrasound was used to capture PRV in both the middle and posterior cerebral arteries. Finally, the bottom right displays representative data from one participant of their 1000 Hz ECG (dark red) and pulsatile waveforms (dark blue) at 1000 Hz. Data were then downsampled to various frequencies, illustrating the impact sampling rate has on the ability to robustly detect the “R-spike” and “P-spike”.
