During an arrhythmia, a heart can beat too fast, too slowly or with an irregular rhythm. "We hope raising awareness will result in clinicians being attentive to risk factors, and avoiding, where possible, medications that can cause or worsen arrhythmias in patients who are at higher risk," said Tisdale, who is professor of pharmacy practice at the College of Pharmacy at Purdue University and an adjunct professor at Indiana University School of Medicine.Īrrhythmias can be caused by genetics, heart disease, high blood pressure, electrolyte imbalances or other factors. Tisdale, chair of the statement's writing committee, said in a news release. "Much remains unknown about the underlying mechanisms of arrhythmias associated with specific medications, and further research is needed to better understand risk factors and treatment options," James E. The American Heart Association scientific statement, published Tuesday in its journal Circulation, examined the effects of over-the-counter and prescription medicines, including some that have been studied for use against COVID-19. Many commonly used medications can cause or worsen irregular heartbeats known as arrhythmias, and health care professionals need to pay attention to the risks, according to a new report.
