Overview

Premature ventricular contractions can occur in a healthy person of any age and frequently occur spontaneously with no known cause.

PVCs are a very common form of arrhythmia, and can occur in both individuals with and without heart disease.
Premature ventricular contractions can occur in a healthy person of any age, but are more prevalent in the elderly and in men.^[1]
They can also occur in otherwise healthy athletes (e.g. in the days following a major effort such as a marathon).
Estimates of the prevalence of PVCs vary greatly.
In children, PVCs occur less frequently than in adults, although healthy children are known to have episodes of PVC. In fact, on routine monitoring of children aged 10-13 years with a Holter monitor, about 20% of healthy boys had occurrences of PVC. In otherwise healthy newborns, PVCs will often resolve on their own by the 12th week of life, and almost never require treatment.
