The accuracy of heart rate monitoring on Apple Watch has been a sought-after feature for wearers of smartwatches and fitness trackers. In medical settings such as hospitals, precision in heart rate tracking is of utmost importance.

While studies have shown that the Apple Watch and other products with optical sensors have advanced in accuracy rate, the FDA has cleared these products as personal health tracking devices, rather than medical devices.

However, the Apple Watch and its Health app have been praised for providing reliable results for heart rate tracking.

Users may wonder if their Apple Watch can misread heart rate. While some may experience inaccurate heart rate data or an unusually high BPM rate, it’s important to note that these instances are rare.

The photoplethysmography technology and optical sensors used in the Apple Watch’s Heart Rate app and Workout app are designed to provide reliable readings.

In the event of a health-related spike in heart rate, the overall heart rate data history can be used to determine if any steps need to be taken.

A study published in the Journal of the American Medical Informatics Association captured the attention of medical researchers and the FDA.

The study, conducted by the Mayo Clinic, urged caution when using personal health tracking devices such as the Apple Watch to screen for asymptomatic atrial fibrillation.

While the life-saving potential of such technology cannot be ignored, false-positive results can lead to unnecessary visits to the doctor and anxiety for patients.

The unintended consequences of over-utilization of direct-to-consumer screening for cardiac diagnosis should be considered with careful consideration.

If a user experiences an issue with their Apple Watch, higher level support from a technician at an Apple service center may be necessary.

While most units and models function without any issues, some complaints may be raised about faulty heart rate readings. In such cases, Apple’s warranty and support will remotely acknowledge the issue and take appropriate steps to fix the hardware issue.

For Apple Watch users who are bench-pressing or exerting themselves during a workout, occasional spikes in heart rate are understandable.

However, if a user experiences alarming readings during normal activity or while sleeping, it may be a cause for concern. In some cases, a bug or sweat build-up may cause a data point to be recorded incorrectly.

In such cases, appointments and tests may be necessary to reproduce the issue and determine a solution.

Doctors and patients alike have been using smartwatches from companies like Apple and Samsung, as well as Fitbit’s Sense smartwatch, as additional tools for monitoring heart health.

These products provide passive monitoring for abnormal heart rhythms and some even have an EKG feature that can alert users to potential cardiac conditions.

While these products have utility as wellness tools, they should not be used as a replacement for a diagnosis by a doctor. The blurring of the line between rigorously-studied medical devices and wearable medical devices requires further understanding and research to fully understand their context and usefulness.
