Cardiac tissue exhibits transmural heterogeneous electromechanical characteristics which are responsible for normal activation, repolarization, contraction and relaxation in healthy hearts. Under abnormal conditions such as myocardial ischemia (MI), the original heterogeneity will be disrupted and may cause the heart out of function. In this paper, a transmural heterogeneous cellular electromechanics...
Cardiac arrhythmias can be sustained by a number of reentry waves, which continuously propagates into recovered tissue and rotates around a central core. In experiments, the reentry waves are usually recorded in two dimensions and the phase singularity (PS) is used to quantitatively study the complex spatiotemporal patterns of fibrillation. In this paper, we propose an automatic method to identify...
