WebThe QT dispersion (QTd) on ECG indicates ventricular repolarization and depolarization. Increased QTd is an indicator of ventricular instability, which thus may lead to severe ventricular arrhythmia and sudden cardiac death. 21, 22 P-wave dispersion (Pd) is defined as the difference between the widest and the narrowest P-wave duration on ECG ... WebP wave = activation (depolarization) of atria. PR interval = time interval between onset of atrial depolarization and onset of ventricular depolarization. QRS complex = depolarization of ventricles, consisting of the Q, R, and S waves. QT interval = time interval between onset of ventricular depolarization and end of ventricular repolarization.

WebIn 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 the PQ interval . WebAn ECG consists of a set of three waves; these are namely the P wave, a QRS complex, and a T wave.
