WebIn most cases, the P-wave is not visible because when impulses are discharged from the junctional area, atria and ventricles are depolarized simultaneously and ventricular depolarization (QRS) dominates the ECG. If the atria are activated prior to the ventricles, a retrograde P-wave will be visible in leads II, III and aVF prior to the QRS complex. WebP-wave is visible in most cases. It is retrograde in leads II, III and aVF and it occurs after the QRS complex (somewhere on the ST segment or early on the T-wave). The retrograde P-wave may simulate an ST-segment …
