Best Blood Pressure Monitor for Atrial Fibrillation (AFib) - 2026
Standard blood pressure monitors can struggle with AFib because the irregular pulse throws off the measurement algorithm. Here are the best options for people with AFib and hypertension.
Important Clinical Note
An irregular heartbeat flag from a home BP monitor is not a diagnosis of AFib. Only an ECG (electrocardiogram) performed by a healthcare provider can diagnose AFib. If your monitor consistently flags an irregular pulse, bring your reading log to your doctor or cardiologist.
Why AFib Makes BP Measurement Harder
Most home monitors use oscillometric measurement. They inflate the cuff and detect vibrations in your artery as pressure drops. The algorithm converts these into systolic and diastolic values by assuming a regular heartbeat pattern.
AFib causes beat-to-beat variation in stroke volume. This makes the vibration pattern irregular and can cause the monitor to under- or over-estimate readings by 5 to 15 mmHg.
Monitors with AFib-adapted algorithms average more readings or use longer sampling windows to compensate. TruRead on the Omron Platinum helps by taking three readings and averaging.

Frequently Asked Questions
Can you accurately measure blood pressure with AFib?
Yes, but it is harder. Standard oscillometric monitors can get inaccurate readings during AFib because the algorithm expects a regular pulse. Monitors with AFib-validated algorithms (like Omron devices with Advanced Accuracy) average more readings or use special detection.
Which blood pressure monitors detect AFib?
Several monitors flag irregular heartbeat during measurement. The Omron Platinum, Withings BPM Core, and Beurer BM67 all display an irregular pulse indicator. However, this is a screening flag, not a clinical AFib diagnosis.
Should I tell my doctor my monitor flagged an irregular pulse?
Yes. An irregular pulse flag during two or more separate readings in one week is worth reporting. Your doctor can order an ECG to evaluate for AFib or other arrhythmias.
Is a wrist monitor safe to use with AFib?
Wrist monitors are even less reliable during AFib than upper arm models. The radial artery reading is more sensitive to pulse irregularity. Stick with a validated upper arm monitor.
How often should I monitor blood pressure with AFib?
Ask your cardiologist. Many people with AFib and hypertension measure twice a day and log every reading. The BPTrack app lets you add a note (like 'irregular pulse flagged') to specific readings.
