Any of [the] following conditions must be met: (a) If the heart disease was known to have been present during employment, there must be proof that an acute exacerbation was clearly precipitated by the unusual strain by reasons of the nature of his work. (b) The strain of work that brings about an acute attack must be sufficient severity and must be followed within 24 hours by the clinical signs of a cardiac insult to constitute casual relationship. (c) If a person who was apparently a symptomatic before being subjected to strain at work showed signs and symptoms of cardiac injury during the performance of his work and such symptoms and signs persisted, it is reasonable to claim a casual relationship. elibrary.judiciary.gov.ph/thebookshelf/showdocsfriendly/1/56107 15/17
