Normal length for pr - Study guides, Class notes & Summaries

The healthcare provider is examining the electrocardiogram (EKG) of a patient and notes the PR interval is 6 small boxes in length. What is the significance of this finding? a) Stress is causing increased sympathetic stimulation b) This should be documented as an expected finding. c) There may be some scar tissue in one of the ventricles. d) There may be a delay in the conduction through the AV node. Ans--d) There may be a delay in the conduction through the AV node. The PR interval re...
