Cal. Lab. Code § 3212.2

In the case of officers and employees in the Department of Corrections having custodial duties, each officer and employee in the Department of Youth Authority having group supervisory duties, and each security officer employed at the Atascadero State Hospital, the term “injury” includes heart trouble which develops or manifests itself during a period while such officer or employee is in the service of such department or hospital.

The compensation which is awarded for such heart trouble shall include full hospital, surgical, medical treatment, disability indemnity, and death benefits, as provided by the workmen’s compensation laws of this state.

Such heart trouble so developing or manifesting itself in such cases shall be presumed to arise out of and in the course of the employment. This presumption is disputable and may be controverted by other evidence, but unless so controverted, the appeals board is bound to find in accordance with it. This presumption shall be extended to a member following termination of service for a period of three calendar months for each full year of the requisite service, but not to exceed 60 months in any circumstance, commencing with the last date actually worked in the specified capacity.
