Thank you for your interest in the project, "Information Theory of the Heart." Please join us any time and share your thoughts!

Why: To identify adaptive mechanisms leading to cardiac arrhythmia in diseased hearts.

To localize the origin of arrhythmia (= wavebreak) and treat it before it happens.
Challenge: Wavebreaks can occur in normal heart tissue. How: Time series from a cellular automata model of the 2-D heart tissue. ?Time series of invasive electrogram from animal or human
What: To quantify information transmission within the heart
Mutual information - Calculate mutual information of two separate locations from binary time series (0–resting, 1–excited). A high mutual information suggests electrical coupling.
