A two-dimensional visual display that allows for the user and/or another individual, such as the user's spouse, to experience self-evident, abnormally complex elevated heart rate arrhythmia. The system of the present invention uses a heart rate monitor, along with data analysis, to provide the user with a visual display, seismic feel, and/or aural feedback that allow for the user to be quickly alerted as to any arrhythmia, thereby signaling to the user to change their activity in order to avoid sudden cardiac death.
