Spiral Waves

Spiral Wave

Spiral waves arise in a variety of natural systems, including cardiac arrhythmias. Ventricular tachycardia, a dangerous fast-paced heart rate, is a result of a sustained spiral wave rotating on the surface of the heart. After the spiral destabilizes, unorganized electrical activity leads to sudden cardiac arrest (SCA) – the leading natural cause of death in the US. I am interested in the stability of spiral waves, and how spectral properties of spirals on bounded domains can provide insight into understanding SCA onset from a mathematical perspective.
