Feasibility of continuous finger arterial pressure recording with synchronised facial video in a hypertension clinic cohort: the BP-WAVE pilot study

Introduction. Whether the arterial pressure waveform carries structural vascular information that brachial pressure does not, and whether its shape can be read from facial video, are both uncertain, and recording a continuous pressure reference with synchronised video in a hypertension clinic has not been reported. We sought to determine whether continuous finger arterial pressure recording with synchronised facial video, linked to existing coronary calcium imaging, is feasible in adults attending a hypertension clinic, whether a consumer camera recovers heart rate and pulse shape in that sett
