PR
Results:
PR Interval: Basics
Key Points Definition: The PR interval runs from P-wave onset to the first ventricular deflection (Q or R). It reflects atrial depolarization plus AV node–His–Purkinje conduction delay. Normal range: 120–200…
PR Segment: Basics
Key Points Definition: The PR segment is the flat line from the end of the P wave to the beginning of the QRS. It reflects conduction through the AV node,…
