Which smartwatches can detect AFib?

Smart Watches that Detect AFib - Top Recommended Options

Several FDA-cleared smartwatches can detect atrial fibrillation, including the Apple Watch (Series 4 and later), Fitbit Sense 2, Samsung Galaxy Watch3, and Withings ScanWatch. These devices use optical sensors to monitor heart rate and rhythm, and some models also include an on-demand electrocardiogram (ECG) feature that provides a 30-second reading to check for signs of afib.

Devices that can detect afib

Apple Watch:
Series 4 and later models offer irregular rhythm notifications and an ECG app to check for afib.
Fitbit:
The Fitbit Sense 2 is FDA-cleared for irregular rhythm notifications. Some other models, like the Fitbit Charge 5, may also have this capability.
Samsung Galaxy Watch:
The Galaxy Watch3 and Galaxy Watch Active 2 are among the Samsung models cleared to monitor heart rhythm for signs of afib.
Withings ScanWatch:
This device has FDA clearance and uses both optical sensors and an ECG function to detect afib.
Garmin:
The Garmin Venu 2 Plus has ECG capability and FDA clearance for detecting arrhythmias.

Optical sensors:
These devices use a photoplethysmography (PPG) sensor to shine a light onto your wrist, measuring how blood flows through your blood vessels. The algorithm analyzes this data to detect an irregular heart rhythm consistent with afib.
On-demand ECG:
Many devices have an app that allows you to record a 30-second electrocardiogram (ECG) by placing your finger on the watch's crown. This provides a more detailed one-lead ECG strip that can be shared with your doctor.

Medical advice:
A smartwatch can help you detect a potential problem, but it is not a substitute for a professional medical diagnosis. If you experience symptoms like a fluttering in your chest, shortness of breath, fatigue, or dizziness, consult a doctor for a proper evaluation.
Data interpretation:
A small percentage of readings can be "inconclusive". Additionally, false positives can cause anxiety.
Continuous monitoring:
The ability to continuously monitor can help capture "silent" afib episodes that you may not be aware of, providing valuable data for your doctor to consider when making treatment decisions.

Is there a watch that can track your blood pressure?

Yes, some smartwatches can monitor blood pressure, with options like the Samsung Galaxy Watch series and the Omron HeartGuide being prominent examples. Other watches, such as some Huawei and FITVII models, also offer this feature. The accuracy of these devices depends on proper calibration with a traditional cuff, which must be done periodically to maintain reliable readings.

Smartwatches with blood pressure monitoring

Samsung Galaxy Watch:
The Galaxy Watch 4 and newer models can estimate blood pressure using their PPG sensor and algorithms, but require calibration with a cuff every four weeks to maintain accuracy, notes kentfaith.
Omron HeartGuide:
This is a specialized watch designed to measure blood pressure manually, and can be programmed for nighttime readings to help detect hypertension.
Huawei Watch D:
This model is mentioned as a smartwatch with a blood pressure monitor.
Other models:
Some fitness trackers, like certain FITVII models, also advertise blood pressure monitoring.

Calibration is crucial:
Smartwatch blood pressure monitors are not equivalent to medical devices and require regular calibration with a traditional cuff for accuracy, according to Braceletsmartwatch.fr.
Accuracy can vary:
Always check the latest reviews and consult with your doctor, especially if you have existing heart conditions.
Intended use:
Many smartwatch features are for general wellness and fitness, and are not a substitute for professional medical advice.
