Electrocardiogram(ECG) is a smart medical technology designed for checking the heart rhythm, much like a heart rate monitor watch. Medical experts use electrocardiograph to measure and spot irregular heart rhythms and analyzes the data to tell if a patient has atrial fibrillation. As technology advances, so is the health care system. Today, you can conveniently, and quickly detect potential heart risks like blood clot, strokes and cardiac failure, without visiting a doctor.
By Wearing an ECG device, you can measure and determine if you have an irregular heartbeat, that could probably cause atrial fibrillation. Most wearables, are recently innovated to include health checking applications, and ECG happens to be a one newer addition to health-related Smartwatches.
Wearing the best smartwatch with ECG on your wrist, means you can keep track of your heart rhythm when it’s convenient for you, without the need to visit doctors. If you find that there’s an unusual ECG reading, that indicates poor heart performance. Considering time, you can quickly measure your ECG in less than a minute and send the generated report to your doctor, as a pdf copy, for further analysis.

What is an electrocardiogram (EKG/ECG) anyway?
An electrocardiograph is a clinical investigation of a humans heart health. Physicians use the ECG procedure , to measures, or records heart rhythm so as to obtain valuable clinical data that is essential to detecting potential heart diseases.
According to the American Heart Foundation, an electrocardiograph “measures the electrical activity of heartbeat”. By measuring the intensity level of the micro electric wave and the frequency(or time) of the electrical impulse propagating from the atria to ventricles, heart experts can determine the status of the heart health.
The advancements in medical technology has made the process faster and easier in these modern times. At first, the gold standard EKG equipment was designed with 12 electrodes which could be placed around the human body, particularly around the torso and the heart.

How does an ECG smartwatch work?
We have already got a glimpse that a clinical electrocardiograph works by detecting some micro currents right from your skin surface. Smartwatch ECG works a bit differently.
A smartwatch with a built-in ECG sensor a has sensitive-light (photo) sensors. These photo sensors uses light beam to detect changes in the blood flowing inside your finger tip or wrist.
Science calls this procedure, as a photo-plethysmograph (PPG). Since Smartwatches are high-tech wearable devices, their algorithm is able to analyze and sort out blood pressure, heart rate variability and ECG, rapidly.

The benefits of ECG
How useful is the smartwatch ECG information? Actually, ECG offers informative clinical data about human heart. There is much that can be known by analyzing how electrical signals flow from one part of the heart(to the other. The primary purpose is that cardiologist can use this data to decide if you have risk of heart diseases or not.
But first smartwatch consumers enjoy access to a personalized heart health data and reports. At the least, individuals, can use this information in prevention and management of their medical conditions.
While ECG smartwatches help offer consumers heart rate monitoring, Electrocardiograph helps to tell health physicians about :
- The Blood flow within your heart,
- The risk of thickening of the cavity walls
- electrolytic ion imbalances. The relative quantities of electrolyte in the body, like Potassium and calcium ions determine the contractions of the cardiac muscle.
- Actually, an ECG smartwatch offers an early detection of cardiovascular diseases , including vascular aging.

Here are other ways in which a smartwatch with an ECG is useful
1. Detection of Atrial Fibrillation (AFib)
Report says that atrial fibrillation – a type of heart arrhythmia, by expectation, can effect 12 million people in the United States by 2030.
This is based on the yearly hospitalization of over 450,000 people affected by afib in the united States.
Because the prevalence rises as you age out, AFib and high blood pressure could be the worse combination in a human life.
Actually afib can be diagnosed and treated, so there is no call for panic when your ECG detects unkown conditions in your heartbeat.
2. Detection of bradycardia or tachycardia
Bradycardia is one of the rhythm abnormalities which can be detected by an ECG smartwatch. It happens when the heart beats at a frequency under 60 beats per minute.
At that low rate, oxygenated blood is pumped from the heart at a low pressure. Distant body parts may tend to suffer for accumulation of waste and low arrival of oxygen. These generally results in a failing body system.
Tachycardia is another rhythm abnormality, where the heart rhythm goes over 100 beats per minute. The final observable signs of these heart rhythm conditions are fatigue, confusion and the difficulty to breathe due to shortness of breath.

Are smartwatch ECGs accurate?
There is some concerns about ecg smartwatch accuracy but First, can a smartwatch diagnose heart attack?
Yes, the smart watch generated ECG, according to reports at Harvard health, are about 93% to 95% accurate at detecting, identifying, and distinguishing heart attacks, for people already having heart problems. This accuracy is quite different for healthier people, as the watch’s ECG accuracy stood at 90% signifying no heart attack.
However, a Smartwatch ECG, is of course, not as accurate as a clinical 12-lead electrocardiogram. Yet, they offer very informative data which can potential lead to deadly heart-health troubles.
For example, Apple Watch from Series 4, 5 and 6 use one-lead electrode for their ECG measurement. It technically Combines both electrical signals and wrist photoplethysmography to provide a greater reliability and an improved ECG accuracy.
Another ecg watch like AliveCor KardiaBand uses a single-lead EKG. As tested and proven by Dr. Kajakariar, Box Hill Hospital, Australia, this one lead ECG has more clinical benefits, with moderate diagnostic accuracy.
Even if your smartwatch alerts irregular heart performance, your heart still needs to be checked and if there are issues, they are addressed by cardiologists . They have very sophisticated instruments for that purpose.
In fact, the best recommendation is that you should not keep waiting because a chronic disease to progress silently. If you pick your own ECG smart device, it holds the potential to ring alarm when your hear beats irregularly. A a smartwatch with EKG is potentially your life saver.
Time is a very critical factor in cardiology. Heart issues that are promptly treated at early stages can add several decades to your age.
Understanding an FDA-approved and FDA-cleared ECG smartwatch
To protect the health of the United States citizens, Food and Drug Administration (FDA) evaluate and regulate medical products to make sure they don’t be of potential health risk for people.
With the rigorous FDA regulatory process , getting a medical device approved isn’t an easy task. You know, the manufacturers need to submit how the medical device performs – results of the clinical test conductor on the product.
Europe and United States don’t follow the same pathways to getting formal approval. So it’s possible that some ECG Smartwatches can be approved in Japan and Europe, but not approved by FDA in U.S.
That also explains why there are not many medical Smartwatches in the market, as compared to GPS Smartwatches, in the market. I guess manufacturers or pharmaceutical laboratories in America needs a lot of patience.
Getting clearance on a medical device may creates risks of manufacturers using old predicates. Do it’s perfect a product be formally approved base on the clinical studies made about it. The big problem with health Smartwatches is that independent trials take a lot of time to be conducted.
Pros and Cons of ECG smartwatches
Back in 2018, American Heart Foundation acknowledged that new wearable technologies related to health, like EKG watches are absolutely be beneficial for patients with heart diseases. But there are some disadvantages
- Price is higher, which then limits accessibility to help determine the health of many.
- a false positive or false negative may occur , leading to more stress and or a non-justified relief.
- Smartwatches have potential breach of privacy even with HIPAA compliance.
- Although they are helping, but there is risk of clinical unreliability with the use of PPG or single-lead EKG.
Wearing a smartwatch with ECG everyday, would be an efficient and timely way to track anomalies in your heart rhythm. The most interesting aspect of having an ECG smartwatch is that you get to analyze your heart beat pattern anytime and anywhere.
ECG Smartwatches are not meant to replace medical tools and expert advice. So while you wear your smart watch with ECG, consult your physician or cardiologist for clinical and diagnostic analysts, immediately you observe irregular heart functions.
