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