University of Maryland School of Medicine researchers have uncovered a previously unknown molecular pathway that is critical to understanding cardiac arrhythmia and other heart muscle problems. Understanding the basic science of heart and muscle function could open the door to new treatments. The study, published recently in the journal Cell, examined the electrical impulses that coordinate contraction in heart and skeletal muscles, controlling heart rate, for example. Unraveling how the body regulates these impulses is key to understanding serious health conditions such as paralysis, muscle relaxation and heart arrhythmia.
