Apple Watch Detects AFib 4x More Often
25 Jan
Summary
- Apple Watch study found AFib four times more often.
- This wearable tech could potentially lower stroke risk.
- Smartwatch diagnosis aids asymptomatic patients significantly.
A groundbreaking study conducted at Amsterdam University's Medical Centre has demonstrated the significant potential of Apple Watches in detecting atrial fibrillation (AFib). Over a six-month period, monitoring over 400 patients aged 65 and above with elevated stroke risk, researchers found that abnormal heartbeats were detected four times more frequently in individuals wearing an Apple Watch compared to those receiving standard care.
This enhanced detection rate, with 21 diagnoses in the smartwatch group versus five in the standard care group, could lead to a reduction in stroke risk. Cardiologists involved in the project highlighted that smartwatches offer a more patient-friendly and continuous monitoring solution than traditional ECG devices, which are often used for shorter periods and can be inconvenient.
The study revealed that a substantial portion of AFib diagnoses made via smartwatch were in asymptomatic patients, who might otherwise have gone undiagnosed for longer. This expedited diagnostic process, enabled by wearable technology combining PPG and ECG functions, not only benefits patients but also offers potential cost savings for the healthcare system. These findings, presented at the European Society of Cardiology's annual symposium, strongly support the use of wearables for long-term screening of irregular heart rhythms.
