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 200 ms in duration. The PR interval is sometimes termed ... Splet26. jul. 2024 · P wave: depolarization of the atria. As gravity helps blood to flow into the ventricles, less muscle contraction is required here. This is why the P wave is smaller than the R and T waves. PR interval: a short pause before the QRS complex; Q wave: depolarization of the top of the ventricular septum by the bundle of His.
