§ 507-d. Disability benefits. A county may elect to make the benefits

provided herein available to the sheriff, undersheriff, deputy sheriffs

who are engaged directly in criminal law enforcement activities, and

correction officers who are in the employ of the county. Notwithstanding

any provision of this chapter or any general or special law to the

contrary, any condition of impairment of health caused by diseases of

the heart, resulting in the disability or death to a member covered by

this section, presently employed and who shall have sustained such

disability while so employed, who successfully passed a physical

examination on entry into service as a member covered by this section,

which examination failed to disclose evidence of any disease or other

impairment of the heart, shall be presumptive evidence that it was

incurred in the performance and discharge of duty, unless the contrary

can be proved by competent evidence.
