Premature Ventricular Complex EKG Interpretation with Rhythm Strip

EKG Features

Rate: The underlying rate
Rhythm: Irregular
P Wave: Absent
PR Interval: Not measurable
QRS: Wide (> 0.10 sec), bizarre appearance
An impulse causes an early cardiac complex which disrupts the underlying rhythm. The locus of stimulation being different, results in a change in the morphology of the cardiac complex. Note the absence of P wave and the wide, bizarre QRS complex. PVC’s can occur occasionally or frequently. PVC’s can be observed with or without a pattern
Premature ventricular contraction couplets are extra, abnormal heartbeats that originating the Purkinje fibers of the ventricles. The PVC occur in pairs. Patients may feel a PVC as a skipped beat or palpitation. Single beat premature ventricular contractions are very common and can often be asymptomatic in healthy patients. PVCs are also called premature ventricular complexes. Premature ventricular contraction (PVCs) are extra, abnormal heartbeats that originating the Purkinje fibers of the ventricles.
