This Credit Card-Like Device Can Measure Your EKG

A company has crammed an electrocardiogram sensor into a card-like device that fits into a wallet, allowing users to take an EKG test on the fly.

A US-based company has come up with a clever little device called the KardiaMobile Card for measuring EKG, and the best part is that it fits in a wallet. EKG or ECG (electrocardiogram or electrocardiograph) is a test that is carried out to check for signs of heart disease by measuring the electrical activity in the heart. The test is usually carried out upon request by a physician, but new technology now makes it possible for people to have them done without the need to visit a hospital.

A feature that is becoming increasingly common on high-end smartwatches and fitness trackers is the ability to measure ECG, thanks to a built-in ECG sensor. The feature made its debut on the Apple Watch Series 4 and is also available on the Galaxy Watch Active 2, Galaxy Watch 3 and the Galaxy Watch 4 series.

The KardiaMobile Card is the latest product from AliveCor, and it stands out from other products based on its design and features. If the name didn’t already give it away, the product is shaped like a credit card which allows it to be easily carried about as it easily fits in a wallet. It is also light and durable, as the product page states its weight is just 7.4 grams and that it will withstand wear and tear, including being sat on but not immersed in water. On the top of the card are two electrodes, a power button, and an LED that lights up when it is powered on. The manufacturer states that the KardiaMobile Card has six arrhythmia detections and can accurately detect AFib (atrial fibrillation), bradycardia, tachycardia, premature ventricular contractions (PVCs), sinus rhythm with supraventricular ectopic and sinus rhythm with wide QRS.

An EKG Scanner In Your Pocket

AliveCor says the product works with the help of a companion app that is available on the Google Play Store for Android devices running Android 6.0+ and on the App Store for Apple devices running iOS 10.3.3+. It connects to a user’s phone via Bluetooth, and all the user has to do is place a finger or the thumb from each hand on the electrodes. The app will state if there is good contact and will take the reading in about 30 seconds. The results will be displayed on the phone. Users will also see their heart rate and can view previous results, download them, and even email them right from the app. It is essential to state that the device isn’t recommended for children and users with pacemakers and ICDs.

While the KardiaMobile Card puts an EKG scanner in your pocket, it also takes money out of it as users need to have a KardiaCare membership which costs $99 per year. The membership provides unlimited EKGs, cardiologist EKG reviews, heart health reports, weight and blood pressure monitoring, unlimited cloud storage, and device replacement. The device replacement is pretty essential as the card has a non-replaceable battery that is expected to provide two years of use. the KardiaMobile Card has been approved by the FDA and is available for purchase on the manufacturer’s website for $149. That price includes a one-year membership which renews automatically after the first year.
