Excerpt
Dynamic changes in blood pressure (BP) are frequently observed in common clinical conditions, including syncope, orthostatic hypotension, postural orthostatic tachycardia syndrome (POTS), and obstructive sleep apnea (OSA). These BP changes occur instantaneously and transiently. For example, a posture change from supine to standing causes an initial large drop in BP within a few seconds resulting in symptoms of orthostatic intolerance; BP decreases rapidly prior to true syncope; and BP surges in seconds during an apneic event in people with OSA. Intermittent brachial BP measurement by sphygmomanometry predominantly used in clinical care lacks temporal resolution to detect these transient, clinically relevant changes. Conversely, continuous beat-by-beat measures can identify and further characterize dynamic BP patterns which may lead to early detection, diagnosis, and/or prevention of cardio- and cerebrovascular events. …
