Court of Appeals of Arizona November 4, 1975, No. 1 CA-IC 1186 (Doolin v. Industrial Commission)

*189OPINION

SCHROEDER, Judge.

The petitioner, William H. Doolin, challenges the sufficiency of medical evidence supporting the decision of the Industrial Commission that his heart attack was not causally related to his employment.

The petitioner was employed as a salesman for the Summit Organization. It is not disputed that he did suffer a heart attack (myocardial infarction) in August of 1973.
