24-hour Ambulatory BP

24 – Hour Ambulatory Blood Pressure 

When blood pressure readings are all over the place – as occurs in 15% of the population, we need a gold standard of BP measurement: the 24-Hour Ambulatory BP.

The 24-Hour Ambulatory BP is conducted with an automated BP Monitor, a “Walkman”- style electronic box  connected to a blood pressure cuff on the arm.

Automatic BP readings are taken at 20-minute intervals through the day and 40-minutes at night. Remarkably, most patients sleep quite well during the procedure.

A small number of patients  are unable to tolerate the device: it is best for them to abandon the procedure and make use of other evaluative technologies.

Results:

Here are some typical patterns of blood pressures as seen on  24 Hour Ambulatory BP

Normal BP: no action required

Mild Hypertension: intervention with lifestyle change or medical intervention (pills) is indicated

 

Ambulatory BP

 

 

 

 

 

 

 

 

White Coat Hypertension: observation-avoid casual BP readings. A Home BP monitor maybe helpful

Hypertension when ‘asleep’ – Nocturnal Hypertension:   implies sleep disturbance where a  Sleep Study may provide evidence of Sleep Apnoea
