Ambulatory blood pressure monitoring

In plain language

What it is

A cuff that records blood pressure around the clock, including during sleep.

Why it matters

It catches day-night patterns and variability that a single office reading misses.

Think of it like

A 24-hour recording instead of one snapshot.

For specialists

Formal definition

24-hour ABPM assesses circadian BP, nocturnal dipping status, and variability; non-dipping marks autonomic dysfunction in post-COVID POTS.

Mechanism

Blunted or reversed nocturnal dipping reflects disturbed autonomic circadian control.
