Ambulatory Blood Pressure Monitor

A single reading in an exam room is a narrow view of blood pressure. An ambulatory monitor is worn for a full day and takes readings automatically while a patient works, moves, and sleeps, producing a far more accurate profile.

When It Is Recommended

White coat hypertension — readings that are high in the office but normal at home.
Masked hypertension — the reverse, where office readings look deceptively fine.
Medication decisions — confirming whether treatment is controlling pressure around the clock.

Nighttime Readings Matter

Blood pressure normally dips overnight, and a pattern that does not is meaningful on its own. The full 24-hour record is reviewed alongside chronic disease monitoring so treatment is based on how pressure actually behaves, not on one measurement.
