Ventricular Dysrhythmias

PREMATURE VENTRICULAR CONTRACTIONS (PVCs) PVCs are due to impulses originating from single or multiple areas in the ventricles. The ECG characteristics of PVCs are as follows:

1. There is a premature and wide QRS complex.

2. There is no preceding P wave.

3. The ST segment and T wave of the PVC are directed opposite the major QRS deflection.

4. Most PVCs do not affect the sinus node, so there is usually a fully compensatory postectopic pause or the PVC may be interpolated between two sinus beats.

5. Many PVCs have a fixed coupling interval (within 0.04 s) from the preceding sinus beat.

6. Some PVCs are conducted into the atria, producing a retrograde P wave (Fig 24:16).
