To observe blood pressure variation in various real-world settings

This is an observational study, which will utilize a wrist-based blood pressure monitor to explore blood pressure variation in up to 75 participants in various real-world settings. There is no intervention in this study. The study will take place over a 4-week period. During this time, participants will be asked to sample their blood pressures 1) at random times, several times per day; 2) during specific periods of either emotional stress or relaxation; 3) during guided orthostatic testing. Study participants will utilize an application on their smartphones to log the device-measured blood pressures and flag selected blood pressure measurements as either being part of the orthostatic testing or during periods of emotional stress/relaxation. At the close of the study a post-study questionnaire will be sent electronically to each participant.
