“…Many studies reported that the accuracy of PPG-based smartwatches for HR measurement during physical activity is generally lower than that during rest [ 10 , 12 , 15 , 18 ]. For example, a recent study published in 2022 by Alfonso et al involving PPG-based, wearable devices reported that this technology demonstrated good-to-excellent agreement in measuring HR during rest.…”

(1) Background: Consumer smartwatches may be a helpful tool to screen for atrial fibrillation (AF). However, validation studies on older stroke patients remain scarce. The aim of this pilot study from RCT NCT05565781 was to validate the resting heart rate (HR) measurement and the irregular rhythm notification (IRN) feature in stroke patients in sinus rhythm (SR) and AF. (2) Methods: Resting clinical HR measurements (every 5 min) were assessed using continuous bedside ECG monitoring (CEM) and the Fitbit Charge 5 (FC5). IRNs were gathered after at least 4 h of CEM. Lin’s concordance correlation coefficient (CCC), Bland-Altman analysis, and mean absolute percentage error (MAPE) were used for agreement and accuracy assessment. (3) Results: In all, 526 individual pairs of measurements were obtained from 70 stroke patients—age 79.4 years (SD ± 10.2), 63% females, BMI 26.3 (IQ 22.2–30.5), and NIHSS score 8 (IQR 1.5–20). The agreement between the FC5 and CEM was good (CCC 0.791) when evaluating paired HR measurements in SR. Meanwhile, the FC5 provided weak agreement (CCC 0.211) and low accuracy (MAPE 16.48%) when compared to CEM recordings in AF. Regarding the accuracy of the IRN feature, analysis found a low sensitivity (34%) and high specificity (100%) for detecting AF. (4) Conclusion: The FC5 was accurate at assessing the HR during SR, but the accuracy during AF was poor. In contrast, the IRN feature was acceptable for guiding decisions regarding AF screening in stroke patients.

“…Devices from popular brands, including Apple (Apple Inc, Cupertino, California, USA), Fitbit (Fitbit Inc, San Francisco, California, USA), Samsung (Samsung Electronics Co., Ltd., Suwon, South Korea), Garmin (Garmin Ltd, Olathe, Kansas, USA), and Polar (Polar Electro, Inc., Kempele, Finland) demonstrate high agreement for HR measurements during sleep and/or rest when compared with criterion measures (i.e. ECG or chest HR monitor) [29–35]; however, as exercise intensity increases, measurement error is more likely to occur [29–32,36,37 ▪ ,39]. The extent of this relationship can be influenced by activity type, arm movement, and device [32,40].…”

Purpose of review The aim of this review is to provide an overview of the use of commercial wrist-worn mobile health devices to track and monitor physiological outcomes in behavioral interventions as well as discuss considerations for selecting the optimal device. Recent findings Wearable technology can enhance intervention design and implementation. The use of wrist-worn wearables provides the opportunity for tracking physiological outcomes, thus providing a unique approach for assessment and delivery of remote interventions. Recent findings support the utility, acceptability, and benefits of commercial wrist-worn wearables in interventions, and they can be used to continuously monitor outcomes, remotely administer assessments, track adherence, and personalize interventions. Wrist-worn devices show acceptable accuracy when measuring heart rate, blood pressure, step counts, and physical activity; however, accuracy is dependent on activity type, intensity, and device brand. These factors should be considered when designing behavioral interventions that utilize wearable technology. Summary With the continuous advancement in technology and frequent product upgrades, the capabilities of commercial wrist-worn devices will continue to expand, thus increasing their potential use in intervention research. Continued research is needed to examine and validate the most recent devices on the market to better inform intervention design and implementation.

“…However, wearable technology faces several important limitations, some biologically inherent and others technological, that avert the proliferation of wearable medical devices, including the lack of high-quality validation studies at different intensity levels [3,13,15,19,42,43,[54][55][56][57][58][59][60][61]. Although accuracy in HR measurement is acceptable in chest strap and electrode-based heart rate monitors, the accuracy of HR measurement in wrist wearables with PPG is uncertain [56,[62][63][64][65][66]. The accuracy of any wearable medical device is increasingly relevant, as it can influence both medical decisions and patient outcomes [15,19,42,43,60].…”

Are Activity Wrist-Worn Devices Accurate for Determining Heart Rate during Intense Exercise?

et al. 2023

The market for wrist-worn devices is growing at previously unheard-of speeds. A consequence of their fast commercialization is a lack of adequate studies testing their accuracy on varied populations and pursuits. To provide an understanding of wearable sensors for sports medicine, the present study examined heart rate (HR) measurements of four popular wrist-worn devices, the (Fitbit Charge (FB), Apple Watch (AW), Tomtom runner Cardio (TT), and Samsung G2 (G2)), and compared them with gold standard measurements derived by continuous electrocardiogram examination (ECG). Eight athletes participated in a comparative study undergoing maximal stress testing on a cycle ergometer or a treadmill. We analyzed 1,286 simultaneous HR data pairs between the tested devices and the ECG. The four devices were reasonably accurate at the lowest activity level. However, at higher levels of exercise intensity the FB and G2 tended to underestimate HR values during intense physical effort, while the TT and AW devices were fairly reliable. Our results suggest that HR estimations should be considered cautiously at specific intensities. Indeed, an effective intervention is required to register accurate HR readings at high-intensity levels (above 150 bpm). It is important to consider that even though none of these devices are certified or sold as medical or safety devices, researchers must nonetheless evaluate wrist-worn wearable technology in order to fully understand how HR affects psychological and physical health, especially under conditions of more intense exercise.
