cardiac electrophysiology correct answer: study of the electrical properties of the cardiac muscle -electricity flows through the heart in a regular, measured pattern and results in contraction of the cardiac muscle -electrical activity precedes mechanical activity (contraction of the heart) -EKG looks at the electrical activity properties of cardiac cells correct answer: specialized cardiac cells have unique characteristics that allow them to regulate heart rate and rhythm characteri...

1. We can choose δx = 0, δy = δ. The equation of the ellipse x = cosθ cosωt y = sinθ cos(ωt − δ) reads in Cartesian coordinates The direction of the axes is obtained by looking for the eigenvectors of the matrix which make angles α and α + π/2 with the x-axis, where α is given by tanα = cosδ tan2θ The vector product of the position ~r with the velocity ~v, ~r ×~v, is easily seen to be so that the sense of rotation is given by the sign of the product sin2θsinδ...
