Heart Model Graphic

Caption

Each rectangular structure represents a heart cell in the computer model. The color bursts depict propagating waves of calcium. Each cell is identical but exhibits a distinct pattern of calcium waves due to random ion channel gating. The team investigated how this randomness gives rise to sudden unpredictable heart arrhythmia.
