Study links ecstasy use with changes in cardiovascular function

Researchers have demonstrated that binge use of MDMA (ecstasy) can significantly alter cardiovascular function, including inducing cardiac arrhythmia and myocarditis, inflammation of the heart wall. In rats injected with MDMA, the risk of cardiac arrhythmia increased and the pattern of mean arterial pressure (MAP) and fluctuations in heart rate changed after repeated MDMA binges.
