The bidomain model describes the electrical properties of cardiac tissue and is often used to simulate the response of the heart to an electric shock. The strength-interval curve summarizes how refractory tissue is excited. This paper analyzes calculations of the strength-interval curve when a stimulus is applied through a unipolar electrode. In particular, the bidomain model is used to clarify why the cathodal and anodal strength-interval curves are different, and what the mechanism of the "dip" in the anodal strength-interval curve is.
Biomedical Sciences: Medical Physics graduate student Sunil Kandel is the lead author on a paper titled “The Strength-Interval Curve in Cardiac Tissue” that appeared recently in Computational and Mathematical Methods in Medicine.
