The nurse is evaluating a patient who has a first-degree AV block, according to the probable diagnosis. He is aware that an ECG strip shows this dysrhythmia by Delayed conduction, producing a prolonged PR interval.
More about PR interval:
Knowing how to estimate a PR interval is crucial whenever a nurse is analysing an EKG. The atrioventricular (AV) node conduction time is represented by the PR interval.
The AV node, also referred to as the electrical system's gatekeeper, is a component of the heart's electrical conduction system. Older persons typically have longer PR intervals, which are shorter when heart rate rises.
