Postural blood pressure and pulse, bedside test for orthostatic hypotension and POTS.
A simple bedside test that measures blood pressure and pulse lying, sitting and standing over 3 minutes. First-line for orthostatic hypotension, postural tachycardia syndrome (POTS), unexplained falls, dizziness and syncope.
Key facts
- 01
Definition
A lying-to-standing blood pressure and pulse test — the bedside standard for postural symptoms.
- 02
A 3–5 minute bedside test
Performed in clinic with a manual or automated cuff — no imaging, no needles, no preparation.
- 03
Orthostatic hypotension
Defined as a drop greater than 20/10 mmHg by 3 minutes of standing.
- 04
POTS in adults
Defined as a heart-rate rise greater than 30 bpm within 10 minutes of standing.
- 05
Complements other tests
Sits alongside 24-hour ambulatory BP monitoring and tilt-table testing for a full picture.
- 06
Foundation of the workup
The first-line test for unexplained falls, dizziness, syncope and suspected autonomic dysfunction.
How the test works
From lying to standing — the seven steps, in order.
A protocol-driven bedside test — the numbers only mean something when the timings and posture are done correctly.
- 01
Consultation and history
Symptom timeline, medication review, hydration and cardiovascular risk factors.
- 02
Lie flat for 5 minutes
A settled baseline is essential — five quiet minutes supine before the first reading.
- 03
Baseline BP and pulse
Recorded lying flat, on the same arm used for the subsequent standing readings.
- 04
Stand — reading at 1 minute
Immediate postural change captured — the early drop that predicts symptomatic falls.
- 05
Stand — reading at 3 minutes
The diagnostic time-point for orthostatic hypotension per international consensus.
- 06
Symptom scoring
Dizziness, visual greying, palpitations and pre-syncope are logged alongside the numbers.
- 07
Structured plan
A written interpretation with medication, hydration and onward-referral guidance.
What it shows
What a postural BP and pulse test detects.
A short bedside test with an unusually broad reach — from drug side-effects to autonomic disease.
-
Orthostatic hypotension
A sustained BP drop on standing — the classical diagnosis this test is designed to catch.
-
Postural tachycardia syndrome (POTS)
HR rise greater than 30 bpm within 10 minutes standing, without significant BP drop.
-
Neurogenic orthostatic hypotension
Autonomic failure in Parkinson’s, MSA, pure autonomic failure and diabetic neuropathy.
-
Volume depletion
Dehydration, GI losses, adrenal insufficiency and post-diuretic states.
-
Drug-related hypotension
Antihypertensives, alpha-blockers, tricyclics and Parkinson’s medications.
-
Autonomic dysfunction
Parkinson’s disease and multiple system atrophy (MSA) with autonomic involvement.
-
Vasovagal susceptibility
A pattern of prolonged standing intolerance with pre-syncopal symptoms.
-
Red flag: syncope with prolonged QT — urgent cardiology
Any collapse with a long QT on ECG is a cardiology emergency, not a bedside answer.
Treatment options
What happens after the numbers.
A staged approach — lifestyle first, medication when needed, specialist referral for the difficult cases.
-
Increase fluid and salt intake
2–3 litres of fluid daily with liberal salt — the first non-drug intervention for most patients.
-
Compression stockings
Waist-high class II compression reduces venous pooling and improves standing tolerance.
-
Review antihypertensives
Dose reduction or switch of alpha-blockers, diuretics and vasodilators where safe.
-
Fludrocortisone or midodrine
Pharmacological support when lifestyle measures are insufficient — under specialist supervision.
-
Physiotherapy for POTS
Structured reconditioning — the evidence-based first-line for postural tachycardia.
-
Autonomic function tests
Formal tilt-table, Valsalva and deep-breathing studies in autonomic laboratories.
-
Cardiology referral (tilt table)
For diagnostically ambiguous or high-risk syncope — a controlled provocation test.
-
Structured follow-up
Serial postural readings to titrate treatment and confirm sustained response.
Red flags
When a postural BP test is not enough on its own.
Signs and scenarios that need urgent escalation — not a routine clinic follow-up.
-
Syncope with head injury
Any collapse causing head trauma warrants same-day assessment — not a routine clinic slot.
-
Prolonged QT on ECG
A QTc greater than 500 ms with syncope is a cardiology emergency.
-
Complete heart block
Third-degree AV block with syncope needs urgent pacing assessment.
-
Autoimmune autonomic ganglionopathy
Rapid-onset autonomic failure — a neurology emergency requiring specialist input.
-
MSA-P or MSA-C
Multiple system atrophy with severe orthostatic hypotension needs coordinated neurology care.
-
Parkinson’s with severe OH
Symptomatic supine hypertension with standing hypotension is a specialist-management scenario.
-
Dehydration with sepsis
Postural drop in a septic patient is an acute resuscitation issue — hospital, not clinic.
-
Aortic stenosis with syncope
Exertional syncope with a systolic murmur mandates urgent echocardiography.
-
Cardiac arrhythmia on ECG
Ventricular ectopy, non-sustained VT or Mobitz II require cardiology triage.

Frequently asked
Everything we get asked about postural BP testing.
Quick answers on how the test is done, what the thresholds mean and when a tilt-table follow-up is needed.
-
What is a postural blood pressure and pulse test?
A bedside test that records your blood pressure and pulse lying flat, then again at 1 and 3 minutes of standing. It is the first-line investigation for orthostatic hypotension, postural tachycardia syndrome (POTS), unexplained falls and postural dizziness.
-
How long does the test take?
Around 3–5 minutes of measurement, after a 5-minute settled period lying flat. Expect roughly 15 minutes in the room including the history and interpretation.
-
How is orthostatic hypotension defined?
A sustained drop of more than 20 mmHg systolic, or more than 10 mmHg diastolic, by 3 minutes of standing — with or without symptoms.
-
How is POTS diagnosed?
In adults, a sustained heart-rate rise of more than 30 bpm within 10 minutes of standing (or more than 40 bpm in adolescents), without a significant BP drop, in the setting of chronic orthostatic symptoms.
-
Do I need to stop my medications before the test?
No — the test is most useful performed on your usual medication, because that reflects your day-to-day physiology. Bring a full medication list.
-
When is a tilt-table test needed instead?
When bedside readings are equivocal, when syncope is unexplained despite normal postural BP, or when a controlled provocation is required for diagnosis. Tilt-table testing is a cardiology or autonomic-lab investigation.

In practice, in London
Getting postural blood pressure and pulse sorted in London, without the guesswork
With postural blood pressure and pulse, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. On the NHS, postural blood pressure and pulse typically sits behind a triage step and a wait that can stretch from a few weeks into months. In London’s private sector, the same appointment often lands within days. That speed matters when symptoms are disrupting work, sleep, or a plan you’d already committed to — and it’s the single most common reason people call us in the first place.
In practice, a private postural blood pressure and pulse appointment in London means a named consultant, a proper hour in the room (or the equivalent on a video call), and a report you can actually read. Most of the imaging suites and endoscopy units we use sit within a mile of Harley Street or in Chelsea and Fulham, and turnaround on findings is measured in days, not weeks. For postural blood pressure and pulse specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
Where a good concierge earns its keep is in the matching. There are dozens of consultants in London who see postural blood pressure and pulse — but not all of them are the right fit for every case. We narrow it down based on subspecialty, insurer coverage, the specific question being asked, and whether continuity into treatment matters. The right first appointment saves you from repeating yourself later.
