Influence of respiration on variability of peak systolic blood flow velocity in common carotid artery: preliminary study

The purpose of this study is to investigate the influence of respiration on variability of peak systolic velocity (PSV) in common carotid artery (CCA). There were significant correlation between peak systolic velocities and its RR intervals that evaluated from synchronized measurement of electrocard...
