Cardiac Monitoring Leads and Premature Ventricular Contractions

Understanding Premature Ventricular Contractions (PVCs)

What are PVCs?

Premature ventricular contractions, also known as PVCs, are extra heartbeats that originate in one of the heart's two lower pumping chambers, called ventricles. These abnormal ectopic beats disrupt the regular rhythm of the heart and can cause sensations like fluttering or a skipped beat in the chest. PVCs are a common type of arrhythmia, which refers to irregular heartbeats. Other terms used to describe PVCs include premature ventricular complexes, ventricular premature beats, or ventricular extrasystoles.

Heart Rhythm in Clients at Risk for PVCs

What Heart Rhythm to Anticipate?

When cardiac monitoring leads are placed on a client who is at risk for premature ventricular contractions (PVCs), the nurse will anticipate seeing premature beats on the electrocardiogram (ECG) rhythm strip. These premature beats will be followed by a compensatory pause, as the heart's electrical system adjusts to the extra beats generated by the PVCs.

The presence of PVCs can indicate underlying heart conditions or other factors that may affect the heart's electrical activity. Monitoring and identifying these abnormal beats are essential in managing the client's cardiac health and preventing potential complications.
