Key Points
- Develop a computationally efficient three-dimensional anatomical computer model of the human atria to investigate the electrophysiological mechanisms underlying atrial arrhythmias.
- Constructed a simplified 3D anatomical atrial model incorporating realistic dimensions and electrophysiological properties.
- Simulated up to 40 seconds of real-time electrical propagation on a single-processor computer.
- Applied a programmed stimulation protocol to test normal sinus rhythm and induce pathological rhythm disturbances.
- Successfully initiated and sustained both atrial flutter and atrial fibrillation within the virtual tissue.
- Demonstrated that simulated atrial arrhythmias depend on an interaction of functional and anatomical reentries driven significantly by atrial geometry.
