   Opinion by

Judge Crumlish, Jr.,

The D. L. Clark Company (Employer) appeals an order of the Workmen’s Compensation Appeal Board affirming a referee’s award of benefits to the widow of Michael Legan based on a conclusion that Legan’s death was due to unusual strain and overexertion in the course of his employment. We affirm.

Employer raises two issues which we will address seriatim:

1. Whether the referee erred in accepting a deatli certificate as proof of cause of death in the absence of other competent evidence.

2. Whether the referee erred in finding that claimant had established a causal connection between death and work by unequivocal medical evidence.

An examination of the second issue will dispose of employer’s first contention. It is well settled that causality must be established by unequivocal medical testimony where it is not obvious. Hudack v. Workmen’s Compensation Appeal Board, 32 Pa. Commonwealth Ct. 508, 379 A.2d 1074 (1977). In this case, the referee found the decedent was in the course of his employment when he died as a result of the unusual strain resulting from his efforts to repair a boiler. Claimant’s physician provided adequate support for this finding by testifying as follows:

Q Doctor, do you have a medical opinion as to the assumed statements of facts which I have given to you as to the certainty of what caused this man’s death ?
A I would have to strongly support that he died of a heart attack.
Q Now, with your opinion then, would you say that the unusual strain brought about by his repairing of these boilers alone without any assistance from anybody, although requested, would be the cause of this man’s death?
A My answer to that would have to be yes.

This testimony was competent evidence as to the cause of death and the referee did not err by admitting the death certificate.

Accordingly, we

Order

And Now, this 6th day of February, 1980, the order of the Workmen’s Compensation Appeal Board dated March 29, 1979, is affirmed. The D. L. Clark Company, self-insured employer,- shall pay to Elizabeth Legan, widow of Michael Legan, compensation at the rate of $95.68 per week for the period beginning October 11,1973 and continuing thereafter in accordance with the provisions of The Pennsylvania Workmen’s Compensation Act.
