Exposure to certain chemicals from e-cigarettes may cause heart arrhythmias. This new study from the University of Louisville suggests some of the cardiac effects of e-cigarettes are similar to or worse than conventional cigarettes. Researchers say certain flavorings or solvents may increase risk for atrial or ventricular fibrillation and, possibly, sudden cardiac arrest. The findings are important because they provide fresh evidence that use of e-cigarettes may interfere with normal heart rhythms—something unknown before. The authors, writing in the journal Nature Communications, expressed their concern because of the rapid growth of e-cigarette use, especially among young people.
