PR interval in ECG shows?
Normal ECG waves and Intervals: ECG wave/Interval Characteristics 1. P Wave Reflects Atrial Depolarization (activation) 2. QRS complex Depolarization of ventricles 3. T Wave Repolarization of ventricles 4. PR Interval Atrial depolarization and conduction through AV node 5. QT Interval Total duration of Ventricular depolarization and repolarization 6. ST segment Plateau phase of ventricular action potential
