Smartwatches aren’t a new technology in our midst anymore. The features coming up on these gadgets are what is wowing the public. The latest of these features is the Electrocardiogram (ECG). This is a new technology geared towards helping people keep an eye on their heart status. It can be used to diagnose Atrial fibrillation (Afib), one of the major causes of stroke.
ECG first came into the limelight through the Apple watch. From there, other manufacturers adopted it and have become more common in wearables. Previously, the optical heart rate monitors were the common heart diagnostic feature. The emergency of ECG moved the heart analysis a notch higher. Heart rate monitors use a flashing LED to detect and analyze the blood flow. This is a less accurate method of diagnosing heart problems. The Electrocardiogram works more like the Electrocardiograph. Instead of measuring the blood flow, it measures the efficiency of your heart. So, you are more likely to get accurate results about your heart using ECG.
The ECG smartwatch are low-risk devices, and it is on those grounds that are easily approved by the FDA. All the manufacturer needs to show is that their product is like ones in the market. However, not all manufacturers have been so lucky to get the FDA clearance. Some are still struggling to get approval so that they can avail the EKG feature to their customers.
How Does A Smartwatch Measure ECG?
An ECG captures the tiny electrical signals generated by the heartbeat. This is what the wearables interpret as a trace to determine whether your heart has any abnormalities. There is a slight difference between the ECG technology in hospitals and the one included in the wearables. For instance, instead of using an electrode, it requires that you place your fingers on the watch’s digital crown for a certain period. The electrical activity of your heart generates a red trace on the watch’s screen. From there, the algorithm inside performs its analysis to determine the health status of your heart. The heart can be normal, also known as sinus rhythm, or abnormal.
The major difference between clinical ECG and that in smartwatches is accuracy. The hospital one is a 12 lead whereas the latter is a single lead. What this means is that the former is stronger. It is capable of capturing more readings about your heart. The single lead takes only one reading which means the results are less accurate.
Is Smart Watch ECG Accurate?
No. Smartwatch ECG uses a single lead system to determine the status of your heart. Its results are based on a single view of the heart, thus are less accurate. Unlike the 12-lead hospital ECG, it cannot be relied upon to detect all heart rhythms. For example, it cannot detect rhythms that occur during a heart attack.
Smartwatch ECG Vs. Clinical ECG
There are several differences between the smartwatch ECG and the clinical ECG. To start with, the clinical Electrocardiograms are more accurate than the smartwatch ECG. The reason is that the clinical ECG uses many leads whereas the latter uses a single lead.
The other difference is the use of electrodes on the hospital ECG. The ECG smartwatches use their digital crowns to collect the electrical rhythms from the fingers. Basically, the clinical tools are more complicated than the ones used on wearables.
Trained medical professionals can only use clinal ECG. Otherwise, you cannot interpret the electrical traces. On the other hand, anyone can use the smartwatch ECG. It is simple with a user-friendly interface and interprets the heart rhythm on its own. So, it’s not a must to have a medical background to use it.
The clinical ECG diagnosis can detect many heart issues than smartwatch ECG. The ECG wearables designed for home use aren’t yet intelligent enough to make some interpretations.
