Noninvasive cardiac T-Wave test
03-25-2007 · EurekAlert!Patients who experience abnormal heart rhythm are often treated with an implantable cardioverter defibrillator (ICD). However, not all patients will benefit from the implant. According to a study presented today at the American College of Cardiology's 56th Annual Scientific Session, a new test called an abnormal T-Wave Alternans test may be able to identify heart failure patients with stage II and III nonischemic cardiomyopathy who are likely to benefit from the use of an ICD.

- Are one-third of costly implanted heart devices unnecessary? New study suggests yes
01-03-2007 · EurekAlert!
This year, tens of thousands of heart patients will have high-tech devices implanted in their chests. Called ICDs or implantable cardioverter defibrillators, the expensive devices are designed to shock damaged hearts back into rhythm and save patients from sudden cardiac death. But a new study finds that while many of these patients will benefit from their ICDs, a large number won't -- and a simple heart-rhythm test can tell who's who.

- Steering atoms toward better navigation, physicists test Newton and Einstein along the way
02-17-2007 · EurekAlert!
''Navigation problems-how to get from point A to point B-tell us about space-time,'' says Kasevich, a professor in the departments of Physics and Applied Physics who will speak about atomic sensors February 17 in San Francisco at the annual meeting of the American Association for the Advancement of Science (AAAS). ''When we build these de Broglie wave navigation sensors, we're also building sensors that can test these fundamental laws about space-time.''

- Technology helps predict outcome of pediatric heart surgery
11-28-2006 · EurekAlert!
Georgia Tech and Emory University researchers have developed an innovative new technology that will help pediatric cardiac surgeons design and test a customized surgical procedure before they ever pick up a scalpel. With a better understanding of each child's unique heart defect, surgeons could greatly improve the likelihood that children with complex defects requiring multiple surgeries over a period of several years could have smoother recoveries and an improved quality of life after their operations.
