Google patents wearable method to predict future heart rhythm issues
Google has filed a patent for a method that uses a wearable device to predict when a user might experience a specific heart rhythm problem called atrial fibrillation. The system first detects an initial heart event using built-in sensors, then monitors the user's heart rhythm over a set period to identify patterns that suggest when the next event might occur.
In the filing’s own words
A method for predicting a cardiac arrhythmia event is provided. The method includes determining a user wearing a wearable computing device has experienced an initial cardiac arrhythmia event based, at least in part, on biometric data obtained from one or more biometric sensors of the wearable computing device. The method includes obtaining biometric data indicative of a cardiac rhythm of the user for an observation period in response to determining the user has experienced the initial cardiac arrhythmia event. The method includes determining one or more temporal patterns of cardiac arrhythmia events of the user during the observation period. The method includes generating a prediction for at least one future cardiac arrhythmia event based, at least in part, on the one or more temporal patterns of cardiac arrhythmia events of the user during the observation period.
What exactly they claim (claim 1)
1. A method for predicting a cardiac arrhythmia event, the method comprising: determining, via one or more computing devices, a user wearing a wearable computing device has experienced an initial cardiac arrhythmia event based, at least in part, on biometric data obtained from one or more biometric sensors of the wearable computing device; responsive to determining the user has experienced the initial cardiac arrhythmia event, obtaining, via the one or more computing devices, biometric data indicative of a cardiac rhythm of the user for an observation period; determining, via the one or more computing devices, one or more temporal patterns of cardiac arrhythmia events of the user during the observation period; and generating, via the one or more computing devices, a prediction for at least one future cardiac arrhythmia event based, at least in part, on the one or more temporal patterns of cardiac arrhythmia events of the user during the observation period.
