Abstract
We present an interactive visualization tool for exploring RR interval data (the time between consecutive heart beats) to support diagnostics. An RR interval sequence diagram allows us to reduce hours of data into a general overview opposed to using short term ECG strips. A simple moving average is applied to the sequence diagram to smooth out short-term variance and highlight long-term trends. The moving average is surrounded by standard deviation bands which allow us to see the fluctuations in variance. After a brief training period using these tools coupled with RR interval and RR interval difference histograms, non- expert participants (undergraduate students) were able to differentiate between normal, atrial fibrillation, and congestive heart failure.
