Virag N, et al. - Researchers performed a prospective, single center study on 140 subjects to evaluate a vasovagal syncope (VVS) prediction algorithm [developed by researchers for use during head-up tilt with simultaneous analysis of heart rate (HR) and systolic blood pressure (SBP)]. In addition, they assessed if retrospective results were reproduced and clinically relevant. They recognized the VVS prediction algorithm to be a clinically-relevant tool and could offer applications including providing a patient alarm, shortening tilt-test time, or triggering pacing intervention in implantable devices.
