Best Smartwatches for ECG functionality

#1

The ECG feature receives strong support from a reviewer’s real family example where on-watch ECG readings caught an irregular rhythm missed elsewhere.

#2

ECG functionality was consistently praised as simple, useful, medically oriented, and easy to share with a doctor.

#3

The expanded sensing surface appears to improve ECG capture, including a smoother experience for one user who had trouble with an older Apple Watch.

#4

ECG was treated as part of Apple Watch’s serious health-safety suite, with reviewers connecting it to potentially life-saving monitoring.

#5

The ECG feature received limited but positive opinionated evidence, with one reviewer saying the wrist measurement worked reliably.

#6

ECG was treated as a valuable health and safety tool when reviewers discussed the health feature set.

#7

ECG is treated positively as part of Samsung Health Monitor’s useful health-tool set rather than as a deeply tested medical feature.

#8

ECG functionality was viewed as dependable and easy to use, with reviewers noting accessible readings and clear reports.

#9

ECG was treated as a mature health function that continued to work seamlessly rather than a major new upgrade.

#10

ECG was viewed as useful and easy enough to access, though some evidence focused on availability and reporting rather than medical certainty.

#11

ECG support helped justify the Pro tier and often worked well, though one reviewer wanted more educational context around the readings.

#12

ECG functionality was usually praised as easy, useful, or medically meaningful, though one reviewer noted setup delays and another found it movement-sensitive.

#13

ECG readings generally worked as expected and one comparison produced results similar to a dedicated Kardia device. It remains a wellness feature rather than a substitute for clinical diagnostic equipment.

#14

The ECG-based Wellness Check is praised as a useful manual HRV reading option rather than a full medical ECG feature.

#15

ECG remains one of the more immediately useful health tools, especially compared with newer trend-based metrics that need longer baselines.

#16

ECG was viewed as useful for intentional HRV readings rather than full medical-grade detection.

#17

The ECG app was treated as a meaningful differentiator against similarly priced competitors, though the reviews did not deeply test ECG accuracy.

#18

ECG was generally seen as a meaningful premium health addition, though reviewers stressed it is manual, sometimes a hassle to enable, and not continuous monitoring.

#19

ECG is viewed as useful for spotting irregular rhythm or saving readings, but reviewers also note manual use and non-medical limitations.

#20

ECG functionality is considered reliable where available, but reviewers noted it is tied to Samsung-phone requirements.

#21

ECG evidence is mixed by review timing: some reviews found it unavailable or finicky, while later evidence notes FDA-approved on-device ECG readings.

#22

ECG is useful as a sensor feature, but reviewers note it lacks diagnostic Afib support.

#23

ECG evidence was limited and lukewarm, with one reviewer finding it interesting but not personally necessary.

#24

ECG functionality was seen as potentially valuable but limited by Samsung-phone restrictions, confusing result presentation, and low personal usefulness for some reviewers.

#25

ECG was a major regional caveat: reviewers liked or valued the feature where available, but repeatedly criticized its absence in the US or North America.

#26

Reviewers noted the lack of ECG as an expected limitation for this price rather than a surprising omission.

#27

ECG functionality was a weakness because reviewers noted the feature is absent and that Garmin offers superior ECG-related capability.

#28

ECG was treated as limited because reviewers emphasized that it is not medically certified and should not be used as a medical device.

#29

ECG was the most repeated missing health feature, often framed as the main reason some higher-risk buyers might step up to the Series line.

#30

ECG functionality is a clear omission because reviewers criticize Garmin for using the older sensor platform without ECG support.

#31

ECG scored low because reviewers noted the watch lacks ECG eligibility or requires accepting the missing feature.

#32

ECG remains absent because the watch retains the older BioTracker sensor generation. One reviewer considered this an overdue omission for the Balance line.

#33

ECG is a clear missing health feature; one reviewer called its absence one of the few serious criticisms.

#34

ECG functionality was treated as a drawback in the review evidence because the feature was built in but not available at the time of testing.

#35

ECG is not available on the Forerunner 170, and reviewers note that buyers must move to a pricier Garmin to get it.

#36

ECG is a clear limitation: a reviewer explicitly wished Garmin had included the hardware for ECG-related features.

#37

ECG is useful as part of Samsung's broad health suite, but its Galaxy-phone requirement sharply limits access for users of other Android brands.

#38

ECG functionality is missing, and one reviewer treated the absent advanced sensors as nice-to-have but not expected at the price.

#39

ECG is a clear limitation because reviewers repeatedly note that the Vivoactive 6 lacks ECG support compared with higher-end Garmin models.

#40

ECG was criticized by omission in a smartwatch-feature comparison because reviewers noted the Vertical lacks ECG functionality.

#41

ECG was a repeated omission: multiple reviewers called its absence strange, frustrating, or a major gap at this price.

#42

ECG functionality was one of the most criticized omissions because the Gen 5 sensor made reviewers expect ECG at this price.

#43

Reviewers repeatedly marked the lack of ECG as a notable omission, especially versus similarly priced or competing smartwatches.

#44

ECG functionality is a weakness because reviewers explicitly flagged ECG as missing or something that might put buyers off.

#45

The absence of ECG is criticized as a gap, especially given the product’s price and female-focused positioning.

#46

Reviewers treated ECG as a missing capability rather than a strength, noting the Venu Sq 2 did not officially include ECG functionality.

#47

ECG was also a limitation: reviewers framed the missing ECG sensor as understandable at the price but still a downside for users who prioritize health metrics.

#48

ECG functionality is scored low because reviewers described the lack of ECG as part of the watch's limited medical-style health feature set.

#49

ECG support was scored poorly because reviewers explicitly noted that ECG functionality is absent despite related electrical sensors.

#50

ECG support was treated as an absent advanced health feature, understandable at the price but still a limitation for serious health tracking.
