A new study published in the Journal of the American Medical Association finds a potential warning sign for three heart rhythm issues—the risk of atrial fibrillation, the need for a pacemaker, and the risk of death.
When EKGs show a prolonged PR interval, that is traditionally considered relatively benign, but that may not be the case. Increases in the length of the PR interval may actually be a warning about the patient's atrial fibrillation risk, need for a pacemaker, or even death.
