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. WebFeb 27, 2024 · PVCs have a characteristic wide and bizarre QRS (usually greater than 0.12 seconds) on the ECG. There is no associated P-wave, and the T-wave records in the opposite direction from the QRS. Most PVCs are followed by a pause until the next normal impulse originates in the SA node.

WebAn interpolated PVC is one which is “sandwiched” between two normal beats and therefore does not have a compensatory pause after the PVC. This is because the P wave (which is hidden in the QRS complex) is still conducted to the ventricles and causes them to contract, although there may be a slight delay.

WebA characteristic sign of A-Fib is the absence of a P wave in the EKG signal.
