Dan Roden and Yuko Wada Find Clue to Drug-Induced Arrhythmias
Researchers at Vanderbilt University Medical Center have made a fundamental discovery about how the heart compensates for genetic variations that otherwise could trigger abnormal and potentially fatal heart rhythms.
Their findings, reported recently in the journal Circulation, add significantly to understanding what causes abnormal heart rhythms, or arrhythmias, and suggest that certain medications can induce them in susceptible people by overcoming the heart’s compensatory mechanism.
