    • Control of cardiac alternans by mechanical and electrical feedback 

      Yapari, Felicia; Deshpande, Dipen; Belhamadia, Youssef; Dubljevic, Stevan (American Physical Society, 2014)
      A persistent alternation in the cardiac action potential duration has been linked to the onset of ventricular arrhythmia, which may lead to sudden cardiac death. A coupling between these cardiac alternans and the intracellular ...

    • Effects of mechano-electrical feedback on the onset of alternans: A computational study 

      Hazim, Azzam; Belhamadia, Youssef; Dubljevic, Stevan (AIP, 2019-06)
      Cardiac alternans is a heart rhythm instability that is associated with cardiac arrhythmias and may lead to sudden cardiac death. The onset of this instability, which is linked to period-doubling bifurcation and may be a ...

    • Mechanical perturbation control of cardiac alternans 

      Hazim, Azzam; Belhamadia, Youssef; Dubljevic, Stevan (American Physical Society, 2018)
      Cardiac alternans is a disturbance in heart rhythm that is linked to the onset of lethal cardiac arrhythmias. Mechanical perturbation control has been recently used to suppress alternans in cardiac tissue of relevant size. ...

    • Numerical modelling of hyperbolic phase change problems: Application to continuous casting 

      Belhamadia, Youssef; Cassol, Guilherme Ozorio; Dubljevic, Stevan (Elsevier, 2023-03)
      Heat diffusion processes are generally modeled based on Fourier’s law to estimate how the temperature propagates inside a body. This type of modeling leads to a parabolic partial differential equation, which predicts an ...

    • A Simulation Study of the Role of Mechanical Stretch in Arrhythmogenesis during Cardiac Alternans 

      Hazim, Azzam; Belhamadia, Youssef; Dubljevic, Stevan (Biophysical Society, 2021-01)
      The deformation of the heart tissue due to the contraction can modulate the excitation, a phenomenon referred to as mechanoelectrical feedback (MEF), via stretch-activated channels. The effects of MEF on the electrophysiology ...
