title: [Ventricular extrasystoles].
abstract: Ventricular extrasystoles result from premature excitation of the heart from a site beyond the bifurcation of the bundle of His, at the level of the conductive tissue or myocardial cells. In practice they represent a daily problem for cardiologists due to their frequent occurrence. They can be detected in symptomatic patients and also in asymptomatic subjects, for example during routine health checks. It is therefore important to distinguish benign ventricular extrasystoles from those which are potentially serious, so that a useless or even dangerous treatment is not undertaken and severe anxiety is not caused in patients who have become 'medicalised'. The decision about treatment is only made following electrocardiographic and echographic clinical investigation, with the presence of cardiopathy being one of the major deciding factors.
