Abstract: The present technology is generally directed to schemas for using dynamic color and pattern backgrounds for electrocardiogram display and associated systems and methods. In a particular embodiment, a method of displaying an electrocardiogram rhythm can include receiving an electrocardiogram signal and applying an algorithm to the signal to determine a rhythm diagnosis or recommended therapy. The method can further include displaying a color and/or a pattern corresponding to the rhythm diagnosis or recommended therapy. In various embodiments, the method can be performed in real time or on a pre-recorded signal for post-event analysis.
