ECG Feature on Apple Watch Could Take Years to Be Approved in the United Kingdom

Earlier this month, Apple unveiled the Apple Watch Series 4 with a new electrocardiogram (ECG) feature that measures the electrical activity of your heartbeat, providing you with a heart rhythm classification that can be shared with your doctor. The feature isn't out yet, but it will be limited to Series 4 models in the United States later in 2018.

Today, 9to5Mac shared a potential time window for the launch of the ECG feature in the United Kingdom. The Medicines and Healthcare products Regulatory Agency (MHRA) explains that the process starts by examining Apple's documentation surrounding the ECG feature and performing an audit of the quality assurance system.

While this step doesn't appear to be lengthy, the proceeding steps could make the process longer. MHRA says it would require Apple to perform a new clinical investigation to judge the effectiveness of the ECG on Apple Watch, but Apple would likely not be able to use any of the data from the studies it's already completed because MHRA requires companies to notify the regulator in advance of a study.

Once the study is submitted, MHRA has 60 days to approve it (which may become longer if the regulators have further inquiries for Apple), and then Apple can begin the study. These last few steps are what the MHRA say "could potentially add years" onto the debut of the ECG in the UK.

You may need to carry out a clinical investigation as part of the process to obtain a CE marking for your medical device. You must inform MHRA if you are planning to do this at least 60 days before starting your investigation [providing] some basic details about the investigational device, the intended population, the type of study, and estimated application date.

The last factor could be the most time consuming and could potentially add years onto the CE marking process.

Despite the potential for years-long approval, Apple may find ways to expedite this process. While the United Kingdom remains part of the European Union, it’s possible that Apple could receive approval from a broader regulatory body and sidestep the MHRA's processes.

In the United States, Apple has obtained de novo FDA clearance for the ECG feature in the Apple Watch Series 4 and the feature that can send a notification if an abnormal heart rate has been detected. However, FDA clearance is not the same as FDA approval and the FDA does not recommend that the ECG feature be used by those under 22 or those who have already been diagnosed with atrial fibrillation.

The FDA warns that Apple's ECG app is not designed to replace traditional methods of diagnosis or treatment and is intended for informational use only.

Elsewhere, Apple has said it is working with Health Canada to bring the ECG functionality to the Canadian market, although no timeline has been specified.
