With modern, commercially available electronics, we can collect the data necessary for the array determination in about 10 milliseconds. Doctors Gorman and Edmunds and their colleagues from the University of Pennsylvania have used this technique to study the pathogenesis of ischemic mitral regurgitation in sheep. Those sheep underwent posterolateral myocardial infarction, which included the posterior papillary muscle. Concurrent echocardiography shows that the mitral regurgitation is between 2+ and 3+. . . .
