WebP-wave abnormalities are associated with left atrial enlargement, left atrial hypertension, and altered conduction [21–23]. To determine these findings in ECG, P-wave morphology, duration, P-wave dispersion (PD), and PR dispersion are used. The difference between the maximal and minimal P-wave durations defines as PD. Web25 de jul. de 2024 · The P wave and PR segment is an integral part of an electrocardiogram (ECG). It represents the electrical depolarization of the atria of the heart. It is typically a small positive deflection from the isoelectric baseline that occurs just before the QRS complex.

WebP wave represents atrial depolarisation which leads to contraction of both atria. QRS complex represents ventricular depolarisation which initiates contraction of ventricles. T wave represents ventricular repolarisation. It represents the return of ventricles from excited state to normal state. WebAn ECG (electrocardiogram) is a test to check the electrical activity of the heart. ECG measures the atrial and ventricular depolarization and repolarization in the form of waves. It comprises of three waves, namely P wave, QRS complex and T wave. P wave in ECG represents atrial depolarization. QRS complex represents ventricular depolarization.
