Cardiac Monitoring Leads and Premature Ventricular Contractions

Understanding Premature Ventricular Contractions (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

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.

The nurse will anticipate premature beats followed by a compensatory pause. What are PVCs?

Premature Ventricular Contractions, or PVCs, are abnormal extra heartbeats originating in one of the heart's lower pumping chambers. They disrupt the heart's regular rhythm and may cause sensations like fluttering or skipped beats in the chest. PVCs are a common type of arrhythmia and are also referred to as premature ventricular complexes or ventricular extrasystoles.
