MICHAEL SILVESTRI vs. COUNTY OF EL DORADO
The Workers' Compensation Appeals Board denied the employer's petition for reconsideration, affirming the finding that Michael Silvestri, a Deputy Sheriff, sustained an industrial heart injury under the Labor Code Section 3212.5 presumption. The Board found that premature ventricular contractions (PVCs) constitute "heart trouble" within the expansive meaning of the statute, even if asymptomatic or not ratably disabling. Defendant failed to rebut the presumption by proving a solely non-industrial cause for the condition.
