| ''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.<br>
| |
| <br>
| |
| ''Hypothesis'': Arrhythmias result from an adaptive mechanism to optimize information transmission in abnormal hearts.<br>
| |
| <br>
| |
| ''Challenge'': Wavebreaks can occur in normal heart tissue.<br>
| |
| <br>
| |
| ''How'': Time series from a cellular automata model of the 2-D heart tissue. ?Time series of invasive electrogram from animal or human<br>
| |
| <br>
| |
| ''What'': To quantify information transmission within the heart<br>
| |
| Potential Metrics<br>
| |
| Mutual information - Calculate mutual information of two separate locations from binary time series (0–resting, 1–excited). A high mutual information suggests electrical coupling.<br>
