Abstract: The present invention relates to an improved heartbeat display and notification system. The system includes retrieving a stream of heartbeat data from an external heart monitoring device. The system further includes storing the retrieved stream of heartbeat data and rendering portions of the stored heartbeat data. Furthermore, the system includes displaying the rendered portions of the stored heartbeat data as a heartbeat rendering. The heartbeat display and notification system also includes determining, and when necessary, updating a user's baseline heart rate. Additionally, the system includes storing the user's baseline heart rate, comparing the user's present heart rate to the user's baseline heart rate. The system further includes generating a heartbeat rendering in response to the comparison and issuing a notification when the difference between the user's present heart rate and the user's baseline heart rate is beyond a pre-defined threshold.
