Vectorcardiography suppose the voltage vector of a healthy heart is given by [0.3, 20.2]. cardiac abnormalities result in changes to this vector. each abnormality can be viewed as a change of a healthy heart voltage vector into a pathological voltage vector through matrix multiplication. for each of the following heart pathologies, find a matrix that produces the pathological voltage vector from a healthy voltage vector. (a) left anterior hemiblock: h =[0.3, 0.2], (b) left posterior hemiblock: h =[20.3, 20.2]
(c) apical ischemia: h =[20.3, 0.2]
(d) chronic obstructive pulmonary disease: h =[0.1, 20.0667]
