A&D Medical UA-767S Upper Arm Blood Pressure Monitor With Atrial Fibrillation Screening

Is a Blood Pressure Monitor With AF Detection Right for You?

High blood pressure affects around one in three adults in the UK, and many people have no idea their readings are elevated until something goes wrong. That is exactly why home monitoring matters. The blood pressure monitor with AF detection from A&D Medical — the UA-767S — gives you a clear, clinically validated reading every time, along with a built-in screen for atrial fibrillation (AF), an irregular heart rhythm that significantly raises the risk of stroke. At just £36.95, it sits within our broader range of electrical health and diagnostic devices designed to help you stay on top of your health between GP appointments.

Atrial fibrillation is surprisingly common — the NHS estimates it affects around 1.4 million people in England alone — and it often goes undetected because it does not always cause obvious symptoms. Having a device that flags potential irregularities during your routine blood pressure check could genuinely make a difference to your long-term health outcomes.

How Does the A&D Medical UA-767S Work?

The UA-767S uses oscillometric measurement technology, which detects oscillations in the arterial wall as the cuff inflates and deflates around your upper arm. These oscillations are converted into systolic and diastolic pressure readings, displayed clearly on the large LCD screen. Alongside this, the device simultaneously analyses your pulse waveform for irregularities.

• The cuff inflates automatically when you press the start button.
• Pressure is measured as the cuff slowly deflates.
• Pulse waveform data is analysed in real time for rhythm irregularities.
• If an irregular rhythm consistent with AF is detected, an AF indicator symbol appears on the screen.
• Systolic pressure, diastolic pressure, pulse rate, and AF status are all displayed simultaneously.

The device stores up to 60 readings in memory, which is useful for tracking trends over time and sharing data with your GP or practice nurse.

Who Should Use the A&D Medical UA-767S?

This monitor is designed for adults who want a reliable, easy-to-use device for home blood pressure monitoring. It is particularly well suited to people who have already been diagnosed with hypertension and need to track their readings regularly, as well as those who have been advised by a clinician to monitor at home. It is also a sensible choice for anyone with risk factors for atrial fibrillation.

• Adults with diagnosed or suspected hypertension.
• People with a family history of heart disease or stroke.
• Those aged 65 and over, who have a higher prevalence of AF.
• Anyone whose GP has recommended home blood pressure monitoring.

How Does the UA-767S Compare to Other Home Monitors?

Is the UA-767S Clinically Validated and Safe to Use at Home?

Yes. The A&D Medical UA-767S has been clinically validated in accordance with established international protocols for blood pressure measuring devices. Clinical validation means the device has been independently tested to confirm its readings are accurate and consistent with those taken by a trained healthcare professional. This is an important distinction — not all home monitors on the market have undergone this level of scrutiny.

If you are already managing a cardiovascular condition or taking antihypertensive medication, using a validated blood pressure monitor with AF detection at home can help you and your clinical team make more informed decisions. If the AF indicator activates during a reading, do not panic — a single positive result does not confirm a diagnosis. Contact your GP for further assessment. You may also find it helpful to explore our vitamins and supplements range if you are looking to support your cardiovascular health alongside monitoring.

This product is a medical device. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is the A&D Medical UA-767S and What Is It Used For?

The A&D Medical UA-767S is an upper arm blood pressure monitor designed for home use. It measures your systolic and diastolic blood pressure and pulse rate, and simultaneously screens for pulse irregularities that may indicate atrial fibrillation (AF). It is used by adults who want to monitor their blood pressure regularly outside of a clinical setting — whether that is because they have been diagnosed with hypertension, are at risk of cardiovascular disease, or simply want to keep an eye on their heart health.

The NHS recommends home blood pressure monitoring as a reliable way to track readings over time, particularly because blood pressure can fluctuate throughout the day and "white coat hypertension" — where readings are elevated in a clinical setting due to anxiety — is a recognised phenomenon. Having your own validated device removes that variable entirely.

What Do You Need to Know Before Using the A&D Medical UA-767S?

Before using this device, there are some important considerations to be aware of. The AF screening function is a screening tool only — it is not a diagnostic instrument. A positive AF indicator should always be followed up with your GP.

Do not use this device if:

• You have a cardiac pacemaker or implantable cardioverter-defibrillator (ICD) — consult your cardiologist first.
• You have lymphoedema or arteriovenous fistula in the arm being measured.
• You are using the device on a child without medical guidance.
• The cuff does not fit your arm circumference (standard cuff: 22–32 cm).

Use with caution if:

• You have severe peripheral arterial disease.
• You have a known arrhythmia other than AF — readings may be less consistent.
• You are pregnant — consult your midwife or GP before monitoring at home.

Device interactions to be aware of:

• Mobile phones and other electronic devices held close to the monitor during measurement may cause interference — keep them at a distance.
• This is a medical device, not a medicine, so drug interactions do not apply. However, certain medications (e.g. antihypertensives, beta-blockers) will affect your readings — this is expected and not a device fault.

How Should You Use the A&D Medical UA-767S?

Getting an accurate reading depends as much on technique as it does on the device itself. Follow these steps every time you take a measurement to ensure consistency.

1. Sit quietly for at least five minutes before measuring. Avoid caffeine, exercise, and smoking for 30 minutes beforehand.
2. Sit with your back supported, feet flat on the floor, and your arm resting on a flat surface at heart level.
3. Wrap the cuff around your bare upper arm, approximately 2 cm above the elbow crease. The tubing should run down the inside of your arm.
4. Press the start button. The cuff will inflate automatically.
5. Remain still and do not talk during the measurement.
6. Once the reading is complete, note your systolic, diastolic, and pulse readings, and check whether the AF indicator has appeared.
7. Take a second reading one minute later and record both results.

What Are the Possible Side Effects of the A&D Medical UA-767S?

As a medical device rather than a medicine, the UA-767S does not carry pharmacological side effects. However, some users may experience minor physical discomfort associated with cuff use. If you are also managing pain alongside your cardiovascular health, our pain relief range may be of interest.

Common effects during use:

• Temporary tingling or numbness in the arm during cuff inflation — this is normal and resolves immediately after deflation.
• Mild skin redness or pressure marks where the cuff sits — usually resolves within minutes.
• Slight discomfort if the cuff is over-inflated due to incorrect positioning.

Less common concerns:

• Bruising in individuals with fragile skin or those taking anticoagulant medication — use with care and consult your GP if this occurs.
• Anxiety related to readings — if monitoring is causing you significant distress, speak to your GP about how frequently you should be checking.

How Should You Store the A&D Medical UA-767S?

Proper storage helps maintain the accuracy and longevity of your device. If you are also storing other health products at home, our first aid collection includes a range of storage-friendly essentials.

• Store in a cool, dry place away from direct sunlight and sources of heat.
• Avoid storing in areas of high humidity, such as bathrooms.
• Keep the cuff rolled loosely — do not fold it sharply, as this can damage the internal bladder.
• Remove batteries if the device will not be used for an extended period.
• Keep out of reach of children.
• Do not expose to extreme temperatures (below 0°C or above 50°C during storage).
