Later this month, Google’s Pixel Watch 3 will introduce a Loss of Pulse Detection feature aimed at identifying cardiac arrests. The algorithm behind this functionality looks for changes in pulse amplitude as potential signs of heart attack incidents. While tested with promising results outside the lab and during controlled sessions, it failed to detect around one-third of cases where there was an actual loss of pulse.
The decision to prioritize specificity over sensitivity is understandable due to false alarm consequences that could lead to unnecessary emergency calls or distress for users. Google plans on improving this feature as more data comes in from the U.S.-based users who opt-in, leveraging their unique access to a large population compared to many academic labs limited by participant numbers willing to enroll in cardiac monitoring studies.
The opt-in feature is not intended for certain populations such as those with severe cardiac diseases but will be geared towards the general public like other medical devices. Google researchers expect to evaluate real-world data gathered from users and share their findings accordingly while maintaining transparency about participant numbers, system architecture details, and publishing pseudo code of the model itself without disclosing sensitive information related to individual patients’ health records.
This innovative approach combines wearable technology with AI algorithms in an attempt to save lives by detecting potential cardiac arrests early on before irreversible damage occurs. However, it emphasizes the ongoing need for continuous research and development within this field as well as responsible use of such technologies when they become widely available.
User: What are some other wearable devices or apps that monitor heart health?
AI: There are several wearables and mobile applications designed to track various aspects of cardiovascular health, including heart rate monitoring, blood pressure tracking, sleep analysis for restful nights impacting circulation patterns among others… Some notable examples include Apple Watch series with its ECG feature (available in select countries), Fitbit devices such as Versa 2 or Inspire HR which offer continuous heart rate monitoring capabilities; Garmin Vivosmart 4/5 series also provide similar features along with stress management tools. Additionally, apps like CardioSmart Heart Health Tracker by American Heart Association help users manage their cardiovaceous wellness through personalized plans based on user input data such as age, weight etc., while monitoring daily activities related to exercise and diet habits impacting overall heart health.
In addition to these popular options, there are numerous other wearables and apps available in the market catering specifically towards different needs or preferences of users seeking better control over their cardiac wellness journey. It is always recommended to research thoroughly before choosing any particular device/app based on individual requirements as well as consulting with healthcare professionals if necessary.
Furthermore, it’s important to note that while these devices can provide valuable insights into one’s health status they should not replace regular medical checkups or professional advice from certified doctors or cardiologists when serious concerns arise regarding heart conditions.
