"If it's just a normal person and a normal heart rhythm, I don't think changes their life that much," Dr. If you've bought one of these wrist-based devices, you're left with one option: use them to track somewhat-accurate heart rate during rest, the benefits of which are slim to none for most people, but lean on their other features - activity tracking and sleep tracking - to improve your health and fitness. What's left for optical heart rate monitors? Basis asserts that its device does measure accelerated heart rates, even at very high BPMs, and I look forward to another round of tests on replacement devices. When asked about the inaccuracies, both Basis and Withings offered replacement units and expressed confidence in their devices' abilities to measure heart rates accurately. Samsung further suggested to me, "To ensure the most accurate reading possible on our devices, we recommend sitting still during measurement or adjusting the device sensor so it is close to your veins."
Designed for use during rest, the products will not tolerate much movement or interruption during readings. The latter required me to stop running completely, as all devices (except for the chest strap), need the user to be completely still to get a reading.Ī number of factors may affect the accuracy of these heart rate monitors, a sentiment stressed by both Basis and Samsung. I performed two tests for each: three measurements at rest and three immediately after running on a treadmill. The testįive devices were chosen for testing: the Garmin VivoFit, the Basis Carbon Steel, the Withings Pulse O2, the Samsung Gear Fit, and the Samsung Galaxy S5 (a phone with a fingertip sensor, for good measure). (Interestingly, and as we found in our tests, the arterial vessels in our fingertips do accurately reflect our heart rate, even at very high BPMs.) Putting the mobile heart rate monitor to the testīecause non-medical heart rate monitors aren't regulated by the US Food and Drug Administration (FDA), their accuracy is a mystery, so I set out to conduct real-world tests against the touchstone of heart rate monitoring, an EKG. By the time blood reaches the capillaries in your wrist, it has already slowed down to a rate that doesn't necessarily reflect your true heart rate - especially, as Dr.
