[Cardiomyopathy induced by frequent premature ventricular contractions].
We report on the rare case of 7-year-old child presenting with frequent and apparently benign premature ventricular complexes (VPC) and left ventricular dysfunction. No structural disease of the heart was seen at cardiological evaluation. Eighteen months after the introduction of an antiarrhythmic treatment with low-dose bisoprolol, Holter monitoring showed 70,000 VPC in 24h with left ventricular function remaining decreased. Six months after increasing the dose of bisoprolol, the VPC were less frequent and left ventricular function was completely normalized. This case was characteristic of a cardiomyopathy induced by frequent premature ventricular contractions.
