Best Smart Watch for ECG functionality

#1

ECG functionality is well supported and repeatedly mentioned as part of the Ultra 2’s robust health suite, including Afib-related features.

#2

ECG functionality is repeatedly mentioned as present and valuable as part of the watch's health feature set.

#3

ECG is treated as a meaningful advantage for the Venu 4, especially because several comparisons note it is included where some Garmin alternatives lack it.

#4

ECG support was clearly present, with reviewers mentioning ECG readings, rhythm checks, and AFib detection.

#5

ECG functionality was one of the strongest health features, repeatedly described as medical-grade, easy to use, FDA-approved, or shareable with doctors.

#6

ECG functionality is one of the strongest health features, with repeated praise for on-demand readings, medical framing, and AFib-related capabilities.

#7

ECG remains part of the health feature set, with reviews listing it among continuing Apple Watch health tools.

#8

ECG is present as part of the health suite, but reviewers tended to mention it alongside other sensors rather than testing it deeply.

#9

ECG functionality is useful and Pro-specific, though availability and certified arrhythmia features may vary by region.

#10

ECG functionality was widely confirmed as a major health upgrade, usually described as manual or snapshot-based rather than passive continuous monitoring.

#11

ECG is treated as a valuable advanced health feature for atrial-fibrillation checks, though not a daily-use feature for everyone.

#12

ECG support is repeatedly listed as part of Apple’s advanced health feature set, though not deeply performance-tested in these reviews.

#13

ECG is consistently present in the health feature suite, with reviewers mentioning ECG/AFib assessment as part of the Pixel Watch 4’s capabilities.

#14

ECG support was available and considered useful or reliable, but access often depends on Samsung's Health Monitor setup and phone ecosystem.

#15

ECG functionality is present and one reviewer calls ECG readings dependable, with others listing ECG among the retained health features.

#16

ECG is repeatedly cited as a valuable health feature, though several reviews note it may require a Samsung phone.

#17

ECG was mentioned as part of the watch's premium health hardware or smart features.

#18

ECG functionality is widely listed as part of the health feature set, though one review notes Samsung-phone pairing requirements for ECG and blood pressure.

#19

ECG support is a Pro-model advantage, though reviewers note context and availability can vary by region or implementation.

#20

ECG support was confirmed through the Elevate sensor, with availability depending on region or approval status.

#21

ECG support is repeatedly noted through the Gen 5 sensor, but availability is region-dependent and not treated as the watch's main draw.

#22

ECG is a valuable health feature, but reviewers repeatedly note that ECG and related rhythm alerts are restricted to Samsung phone users.

#23

ECG support was a mixed point across reviews because availability changed by region and timing; where available, it added useful heart-rhythm checks.

#24

ECG is present, but reviewers repeatedly note limitations such as no Afib detection or lack of FDA-style diagnostic support.

#25

ECG-based wellness checks are available, but reviewers note it is not a medical-grade ECG and is mainly for HRV/metrics.

#26

ECG evidence is mixed by review timing: one source notes a firmware update enabled ECG, while another earlier review says it was not yet available.

#27

The watch includes ECG-related hardware mainly used for HRV-style readings, but evidence frames it more as wellness data than full medical ECG functionality.

#28

ECG functionality exists, but reviewers consistently frame it as non-medical and not an atrial-fibrillation detection tool.

#29

ECG was valued as an advanced health feature, but multiple reviewers noted Samsung-phone or app restrictions.

#30

ECG support is a major caveat: hardware or global support exists, but US and North American availability is repeatedly criticized.

#31

ECG-style wellness readings are included, but reviewers repeatedly stress that the feature is not medically certified and does not detect AFib.

#32

ECG evidence is conflicting: one review listed an electrocardiogram sensor, while another explicitly said the Pace 4 lacks the sensors required for ECG readings.

#33

ECG evidence was mixed by timing: some review content described ECG capability, while others said it was not enabled or certified at launch.

#34

ECG functionality is a clear omission from the regular Fit 4, appearing as a Pro-model advantage rather than a base-model feature.

#35

ECG functionality is weak or absent in the review evidence; reviewers explicitly note no ECG, with only speculative or future-support language elsewhere.

#36

ECG is the most mixed-but-mostly-negative attribute: most reviewers say it is missing, while one transcript says ECG is included.

#37

ECG functionality is absent; reviewers repeatedly state the Venu Sq 2 has no ECG feature and that Garmin ECG support was limited elsewhere.

#38

ECG is effectively absent from this MARQ evidence, with reviewers pointing to Venu 2 Plus as Garmin’s ECG-capable design instead.

#39

ECG functionality is absent on the Versa 4, a repeated contrast with Sense models and some cheaper Fitbit alternatives.

#40

ECG functionality was consistently absent because the watch uses the older Garmin sensor platform rather than the Gen 5 feature set.

#41

ECG functionality is the clearest omission: many reviewers criticize the lack of ECG despite the newer heart-rate sensor and the price.

#42

ECG functionality is absent, and reviewers repeatedly call this one of the main health-feature tradeoffs.

#43

The Forerunner 965 lacks ECG hardware, a repeated limitation compared with Garmin’s Venu line and newer or more smartwatch-oriented alternatives.

#44

ECG is consistently absent because the watch uses Garmin’s older Elevate sensor generation.

#45

ECG functionality was consistently absent; reviewers repeatedly stated users need a different or higher-end Garmin for ECG/EKG.

#46

ECG functionality is consistently absent; reviewers repeatedly note that the T-Rex 3 Pro does not include ECG support.

#47

ECG is a clear missing feature, with multiple reviewers explicitly stating the Watch 2R cannot take ECG readings.

#48

ECG functionality is absent; reviewers explicitly state that the Forerunner 265 lacks the required hardware or ECG app support.

#49

ECG functionality is absent, with reviewers explicitly noting no ECG or medical-style electrocardiogram feature.

#50

ECG and Afib-related features are missing on the Light, pushing heart-health-focused buyers toward other ScanWatch models.
