Dr. Peter Zimetbaum, a professor at Harvard Medical School, envisions a future where the widespread use of digital technology for personal health applications becomes the norm. Smartwatches, for example, offer a wide array of functionalities, from monitoring daily step counts and encouraging physical activity to assessing blood oxygen levels during periods of stress. They can even enable users to record clinically relevant Electrocardiograms (ECG or EKG) in less than 30 seconds.
As per Harvard Medical School, a staggering 160 million individuals are poised to embrace health and fitness tracking through wearable devices. We find ourselves in the midst of a profound transformation, where real-time connectivity and the quantification of personal healthcare will play a pivotal role. However, it’s important to note that the field of wearable technology faces the challenge of limited acceptance and clearance by the Food and Drug Administration (FDA).
Choosing the optimal wearable ECG device for either iOS or Android is a critical step in obtaining dependable results. This article will delve into the leading smartwatches currently on the market, designed to support heart health management.
Best Smartwatch with ECG Monitor Reviews
1. SAMSUNG Galaxy Watch 4 Smartwatch with ECG Monitor
The Samsung Galaxy Watch 4 is a smartwatch that seamlessly blends into various settings, thanks to its distinctive rotating bezel. It’s a versatile choice that transitions effortlessly from the boardroom to the gym. Android enthusiasts have an uncomplicated decision to make, with two models available: Watch 4 and Watch 4 Classic. Both versions offer contemporary, high-end aesthetics and an array of exercise and wellness features.
Similar to the Apple Watch, the Samsung Galaxy Watch 4 can detect bradycardia, tachycardia, and atrial fibrillation. It boasts a battery with a commendable 40-hour mixed-hour lifespan. The device is well-equipped to monitor a range of health metrics, including blood pressure, ECG, and blood oxygen saturation, along with identifying irregularities in heart rhythm, such as Atrial Fibrillation.
The Samsung Health Monitor app provides a secure platform for storing health data, enabling users to generate PDF reports to share with their healthcare providers. In today’s data-driven world, the Galaxy Watch 4 is a compelling choice, especially given its more budget-friendly pricing, making it a relatively affordable option.
2. Apple Watch Series 7 Smartwatch with ECG Monitor
Undoubtedly, the Apple Watch Series 7 ranks among the finest smartwatches available, and its appeal extends beyond ECG monitoring. It seamlessly combines ECG tracking with features like fall detection and sleep monitoring. While its battery life may be the only potential drawback, the Apple Watch’s vast array of functionalities makes it a clear standout.
The latest Apple Watch TV commercial prominently features the ability to perform an electrocardiogram at your convenience, highlighting its significance. The Apple Watch employs a combination of a 1-lead EKG and PPG (Photoplethysmogram). In under 30 seconds, the results are displayed as follows:
- “Atrial Fibrillation,” indicating an irregular heart rhythm.
- “Sinus Rhythm,” signifying a regular and normal heart rate.
- “Low or high heart rate,” potentially indicating episodes of bradycardia or tachycardia.
If you receive any of these results, it’s advisable to consult with your healthcare provider. The Apple Watch’s multifaceted capabilities and user-friendly design make it a top choice for those seeking ECG monitoring and a range of other health-related features.
3. Fitbit Sense Smartwatch with ECG Monitor
Fitbit’s latest model, the Sense, offers a comprehensive suite of features expected from a fitness watch, including ECG readings. However, its standout feature is stress monitoring, which is facilitated through the Electro Dermal Activity (EDA) sensor, capable of measuring both skin temperature and stress levels. It’s worth noting that some users have reported issues with the inductive side button occasionally activating unintentionally. Nevertheless, the Sense provides a level of ECG functionality on par with its competitors.
To perform an ECG with the Sense, you need to complete the electrical circuit by placing two fingers on the Sense’s rim and wait for 30 seconds. It’s important to note that measurements of blood oxygen saturation and body temperature are only taken during sleep. Consequently, the data is averaged, making it less suited for obtaining immediate post-exercise measurements.
Regrettably, the Fitbit Sense has faced criticism for being less responsive compared to other devices, leaving many users feeling that it’s still in a developmental phase. However, there is potential for the Sense to fully realize its capabilities with future software and hardware updates.
4. Withings Smartwatch with ECG Monitor
For individuals involved in exercise or training, monitoring workouts and progress is a vital aspect of their regimen. While smartwatches from brands like Apple and Garmin are favored by both fitness professionals and enthusiasts, they often lack the aesthetic appeal of traditional timepieces, appearing more like tech gadgets strapped to your wrist. But what if you desire a different option?
The Withings ScanWatch offers an elegant solution in such cases. It retains the classic appearance of a traditional watch while seamlessly integrating smartwatch capabilities. This includes features like an in-built ECG monitor, GPS, step tracking, heart rate monitoring, and the ability to monitor a diverse range of exercises, from running and cycling to swimming and weightlifting.
5. Fitbit Charge 5 Smartwatch with ECG Monitor
Fitbit has recently enhanced the Charge 5, delivering on the promises made at its launch by incorporating features like the Daily Readiness Score and the electrocardiogram app (ECG or EKG). The device offers comprehensive fitness monitoring, a vibrant display, extended battery life, and compatibility with both iOS and Android.
The inclusion of the Daily Readiness Score in the Fitbit app presents an intriguing solution to the puzzle of optimizing your daily activities. This feature assesses your data and provides personalized recommendations, guiding you on whether you should engage in specific exercise goals or opt for relaxation through meditation sessions. Although this score is now accessible to users of the Charge 5 and other Fitbit trackers and watches, it’s exclusively visible to Fitbit Premium subscribers with tailored recommendations.
Overall, the Charge 5 stands out as a compelling choice for individuals seeking a tracker equipped with built-in GPS, ECG functionality, robust sleep and exercise tracking, and exceptional battery life. As we delve deeper into the utility of the Daily Readiness Score, a more comprehensive evaluation of its effectiveness will be needed.
How Smartwatch ECGs Function?
Smartwatch ECG sensors operate differently from traditional clinical electrocardiograms. Instead of relying on the detection of micro-currents at the skin’s surface, they utilize light beams and light-sensitive sensors to perceive variations in blood circulation at the wrist. This technique for measuring heart rate is known as Photoplethysmography (PPG). Subsequently, algorithms process the signals, extracting data such as ECG readings, blood pressure, and heart rate variability.
In a 2018 evaluation conducted by Dr. Castaneda and colleagues, the potential applications of wearable photoplethysmography sensors in healthcare were explored. Their findings suggested that PPG has the potential to provide healthcare professionals with early diagnoses of various cardiovascular conditions, including vascular aging. It is essential to minimize the impact of motion artifacts on the quality of the PPG signal after data acquisition.
