The PR interval of the surface ECG is measured from the onset of atrial depolarization (P wave) to the beginning of ventricular depolarization (QRS complex). When the heart's ventricles can't get information from the sinus node about how fast to beat, they use information from another part of the heart between the atria and ventricles, called the AV node. In some cases, this is normal, such as sinus tachycardia during exercise or sinus bradycardia in athletes.
