Dynamics of Spiral and Scroll Waves in a Mathematical Model for HumanVentricular Tissue : The Effects of Fibroblasts, Earlyafter depolarization, and Heterogeneities
(20180709)This thesis is devoted to the study of the dynamics of spiral and scroll waves in a mathematical model for cardiac tissue. We study the effects of the presence of heterogeneities on electricalwave dynamics. The heterogeneities ... 
Electrical waves in mathematical models of humanventricular tissue: effects of different modeling formalisms, electrophysiological factors, and heterogeneities on ventricular arrhythmias and the termination of these arrhythmias via a deeplearning approach
Sudden cardiac death (SCD) remains one of the significant causes of mortality in industrialized and developing countries. SCD is often caused by lifethreatening cardiac arrhythmias like ventricular tachycardia and ...
