These irregularities did not interfere with normal lifespan extraasistolia they were occasional but an ominous prognosis was implied if they were frequent. The ability of frequent PVCs originating from a focal source in triggering idiopathic ventricular fibrillation VF in seemingly normal hearts was first reported by Haissaguerre et al. If PVCs are frequent or troublesome, medication beta blockers or certain calcium channel blockers may be used. The length and morphology of PVCs are highly variable and depend on the place of origin, the presence of structural heart disease and treatment with antiarrhythmic drugs.
