<P> In electrocardiography , the PR interval is the period , measured in milliseconds , that extends from the beginning of the P wave ( the onset of atrial depolarization ) until the beginning of the QRS complex ( the onset of ventricular depolarization ) ; it is normally between 120 and 200ms in duration . The PR interval is sometimes termed the PQ interval . </P>
