Premature Ventricular Contractions PVCs Animation. Atrial arrhythmia including AF and atrial flutter are the most common. The estimated prevalence ranges from 1 to 4 on electrocardiogram and 40 to 75 on a24 or 48-hour Holter monitor Young and healthy adults have showna highly similar frequency rate of PVCs in contrast to the older segments of.
