the electrical triggers of the various kinds of heart disease could lead to earlier diagnosis and new treatment breakthroughs. In order to understand what the mechanisms of the particular disease are, the heart must be modeled with enormous detail. Once disease mechanisms are fully understood, scientists will be able to devise the best drug or the best cure surgical or other remedies -- and doctors will be able to diagnose much more precisely. Without the use of computer models it can be hard to track the effects of a heart disease on the ECG.
