provided herein available to the sheriff, undersheriff, deputy sheriffs
who are engaged directly in criminal law enforcement activities, and

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.
