New method allows heart beat triggers to be viewed and better understood

Researchers have developed unique chemical dyes that have made it possible to see what the naked eye has never seen before: action potentials, or voltage changes, of cardiac cells - including those deep inside the heart, which trigger and determine the pace of heartbeats.

Fluorescence spectroscopy able to detect the presence of inflammatory cells that are associated with critical atherosclerotic plaques

Because atherosclerotic plaque typically builds up without symptoms and leads to more than 1 million deaths in America each year, the search is on to develop early detection devices that will enable physicians to offer treatment before the disease progresses to advanced stages.
