London : A new research has shown that an infrared laser can make aheart beatfaster, which may help in understanding reasons for congenital defects.Case Western Reserve University and Vanderbilt University researchers have found that pulsed light can pace contractions in an avian embryonic heart, with no apparent damage to the tissue, reports Nature.
According to the scientists, this non-invasive device may prove an effective tool in understanding how environmental factors that alter an embryo''s heart rate lead to congenitaldefects.
It may also lead to investigations of cardiac electrophysiology at the cellular, tissue and organ levels, and possibly the development of a new generation of pacemakers.
