New mechanism for cardiac arrhythmia discovered

"It has long been thought that virus infections can cause cardiac arrhythmia. But why has not been understood. Ulrike Lisewski, Dr. Yu Shi, Michael Radke and Professor Michael Gotthardt of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now discovered the molecular mechanism. The researchers demonstrated that the receptor which the virus uses to infect heart cells is normally necessary for regular heart beat in mice..." - PhysOrg.com
