Mathematical tools and techniques have improved the understanding of cardiac arrhythmias, according to a University of Utah distinguished professor of mathematics who will lecture on the subject this evening.

James Keener will give the "Frontiers of Science Lecture" sponsored by the U.'s College of Science and College of Mines and Earth Sciences. The program begins 7:30 p.m. in the Aline Wilmot Skaggs Biology Auditorium on campus, immediately west of the bookstore.

"Heart attacks can be fatal when there is a subsequent disruption of the normal electrical signal of the heart, leading to fibrillation," says a release from the university. "Why this occurs is still not fully understood and, medically speaking, there are no reliable predictors for the onset of fibrillation."

Keener will show how math has improved our understanding of what arrhythmias are, how they happen and how they can be prevented, it adds.

The lecture is free and open to the public. For information, including parking directions, call 581-6958 or check the Internet site www.science.utah.edu.
