The Apple Watch comes with a built-in heart rate monitor but there can be many problems when it comes to pinpointing when you are going to get a heart attack or predicting a stroke in advance. There are certain factors like how the strap of Apple Watch fits around your wrist and how you normally move your wrist, that can prevent the watch from accurately reading your heart rate. Even if you have a tattoo on your wrist it can have an impact on the way the watch assesses your heart rate. So if you solely want to depend on Apple Watch in order to predict your heart attack, you can be in a vulnerable position.
But it doesn’t mean Apple Watch is useless if you’re looking for some reliable gadget to predict an impending heart attack. There is an accessory that you can use with Apple Watch the can give you an accurate reading of your heart rate.
New KardiaTM is a band for Apple Watch that can provide you a medical-grade electrocardiogram on the go. The band that is pending 510K clearance, which it may get this late spring, is available along with a new app that connects the capabilities of the band with your smartphone. The technology used by this new band for Apple Watch, as claimed by the company, can help you predict your heart attack because it uses an electrocardiogram technology that is commonly used by health professionals.
Here is a video of how the Kardia band for Apple Watch can help you predict a heart attack:
According to this Time report, the Apple Watch’s heartrate sensors work through photoplethysmography, which flashes LED lights hundreds of times per second to monitor blood flow through your wrist. This allows the watch to get a sense of how many times your heart beats per minute. The electrocardiogram sensors of the new band for Apple Watch, instead of relying on the wrist, directly monitor the electrical signals that are produced by your heartbeat, according to the American Heart Association (this statement is for the electrocardiogram and not particularly for the new band for Apple Watch).
According to the company, AliveCor, the sensors in the band can detect Atrial fibrillation, which is an irregular heart rate that can increase the risk of heart attack and also other heart complications. The band can also tell you whether your heart rhythm is normal and how is your heart rate and it can alert you when the reading isn’t what it should be even if somehow there is a chance that the data is unreliable.
As mentioned above, there is an accompanying app that you need to install on your iPhone or iPad. The Apple Watch band feeds the data into Apple’s Health app where you can analyse your EKG reading along with other health related information.
