Prolonged PR Interval on EKG Warns of Atrial Fibrillation Risk, Pacemaker, or Death

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.

  1. Roger Ansell says:

    I’ve had A Fib since 9/11/02 3 years ago I had a pacemaker installed and was to receive ablation but suffered a heart attack and had to have 6 bypasses. As of the first of May this year, 3 years after the bypass I have gone into almost continuos AFib this has made me very weak and sick most of the time. The pacemaker does not seem to help. I am 75, was very active physically and now am an invalid. Is it possible to have the ablation to stop the AFib rogue heartbeat, given my history.
