Apple Watch, ver 4.0 offers EKG monitoring with a monitoring and notification feature. This adds a new function to the already ubiquitous Apple Watch. Unfortunately the older Apple Watch cannot be upgraded, requiring a rather expensive new purchase.
The Apple Smart Watch ver 4.0 has an FDA approval, but is not completely certified as a medical devide.
There are however several devices coming to market.
Polar’s latest Vantage fitness watches are now available for purchase
In September, Polar announced its latest wearables — the Polar Vantage V and the Polar Vantage M, both of which provide a new optical heart rate sensor, additional tracking metrics, and more. The fitness watches are now available for purchase and are shipping out for those who pre-ordered either one at launch.
Both the Vantage M and Vantage V can be bought through Polar’s website. The Vantage M will cost you $280. The Vantage V is a bit more pricey, coming in at $500 in either black, orange, and white, in sizes medium and large — small bands can be bought for about $10. You can also opt for the heart rate bundle, which comes with the Vantage V and Polar H10 heart rate monitor for $50 more.
For the most part, the Vantage M and Vantage V are packed with the same features. Under the hood, you will find Polar Precision Prime — Polar’s new wrist-based heart rate technology. With three sensor types and new electrode sensors to measure skin contact, both wearables are expected to have higher accuracy and a quicker response time when it comes to measuring heart rate.
Both watches also offer continuous heart rate and activity tracking. That way, even on days you’re not training, the Vantage M and Vantage V provide you with daily calorie burn and insightful data in terms of your everyday activity.
Polar's offering will set you back $250 to $500 depending on the options.
In an emergency, KEZ offers both 360° real-time video to immediately assess the situation and GPS location tracking so you can rush to your loved one’s side. Triggered by an automated bio-sensor, KEZ requires no action on the part of the person in distress. Capable of measuring bio-rhythms including heart rate, blood pressure and body temperature, KEZ’s patented algorithm will monitor bio-data in real-time to only alert you in times of abnormal readings or urgent emergency. Sometimes there is no time to explain the emergency. Equipped with a 360° fish-eye camera, when an emergency is triggered, KEZ will automatically begin to record the situation. Activated only in emergency situations, the camera will record for 15 sec. in a 360°FOV (field of view) and automatically transmit the video to the guardian.
Beyond alerts and a video record, KEZ will also determine the exact location of the wearer in crises. Real-time GPS tracking provides the exact address and map location. Even if they are unable to tell you, never feel hopeless and always know where to go respond to.
When an emergency is triggered, KEZ will record and transmit an emergency alert in 40 seconds or less. SOS alert will include video of the surroundings and recording of the immediate danger. Appraise the situation & take action immediately.
