Aberrant Conduction or Ventricular Bigeminy?

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. hughie j bradshaw whiting nj https://imoved.net

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.
