Do you trust the Apple Watch for heartbeat detection?

Consumers of the different versions of the Apple Watch use the wearable mainly to help them in their exercise routine and from time to time measure in cardio routines, how well or badly the heart pulsations are.

The device that registered sales for 31 million units in 2019 and also measures the quality of sleep and delivers personalized notifications, includes an ECG application that isapprovedby the U.S. Food and Drug Administration. UU. (FDA) for the detection ofatrial fibrillation (AFib)An anomaly of the heart that is associated with an increased risk of stroke, including those that could lead to death.

In that last section un 2019 study published in the New England Journal of Medicine (NEJM) examined this function of wearable by smart watches of "irregular pulses" in almost 420,000 people for eight months. In this study, "which was funded by Apple, the authors concluded that Apple Watch was effective in detecting AFib, stating that 84% of smart watch notifications were accurate to warn about atrial fibrillation."

Apple Watch on the user's face

However, what this prestigious investigation did not take into account, is that Apple Watch does not detect AFib pulsations greater than 120 beats per minute, in information that the same brand was responsible for clarifying when I sent its parameters to the FDA (agency of United States responsible for the regulation of food, drugs and drugs).

That being fair, it should be noted that the same brand on its support page provides that information, about the things that the smartwatch is not able to do and when a specialist should be consulted.

  • Apple Watch cannot detect heart attacks.If you ever experience chest pain, pressure, pressure or what you think is a heart attack, call emergency services immediately.
  • Apple Watch does not constantly search for AFib. This means that Apple Watch cannot detect all instances of AFib, and people with AFib may not receive a notification.
  • If you do not feel well, you should talk to your doctor even if you do not receive notification. Symptoms such as fast, heavy or agitated heartbeats, dizziness or fainting may indicate a serious condition.
  • Do not change your medication without talking to your doctor.
  • In some cases, the notification may indicate the presence of an irregular heart rhythm other than AFib.
