Appellant’s husband, Dan M. Farmer, a carpenter by trade, 56 years of age, on February 14,1949, was employed as a carpenter on a high school building-in Crossett by L. H. Knight Co., appellee. Farmer had *334been working on this job for about one week with another carpenter of appellee, John Midgett, and after having worked for about seven hours on the 14th, a timber 4"xl0"xl6', weighing from 125 to 150 pounds, was placed by two helpers on horses, on a scaffold about seven feet from the ground. While lifting one end of this timber about one foot, Farmer suddenly collapsed, fell from the scaffold to the ground and died almost immediately. Midgett and another carpenter, Mr. Horn, were the only witnesses with Farmer when he fell.
Mr. Midgett, who was assisting Farmer and-lifting the other end of the timber, testified: “Q. How high did he have to lift the piece of timber after he got it over the wall ? A. Oh! I would say now if it was on the scaffold about two feet, but he had it up to his knees to start with. I would say 10, maybe a foot high; not over that. Q. What kind of position was he in? A. Well, he was just standing up like a man would picking up anything. Q. Have to bend over to lift it, put it in? A. Yeah! I guess he did have to kinda get down a little. Q. You ing you are in that position lifting the board of that kind at the place, would you be in a strain? A. No, no, if you didn’t go no higher than that you wouldn’t. You are right even with your body; waist high about that. * * * Q. Now, you are how large, how much do you weigh? A. I weigh 145. Q. Was it a very difficult thing for you to handle one end of a four by ten by sixteen? A. No, sir. Q. It wasn’t heavy work to you? A. No, it wasn’t too heavy for me. * * * Q. February 14 was on Monday? A. That’s right; it was on Monday he went to work there a had been there since Monday. Q. And you wouldn’t say this was any heavier work than you had done all the week before that? A. No, sir, I wouldn’t. Q. This was the second Monday? A. Yes, sir. Q. That he one week? A. Yes sir. Q. And you had never heard him complain of either feeling bad or that the work was heavy? A. Never heard him say nothing; no, sir.”
The Commission summarized Mr. Midgett’s testimony: “John Midgett testified he was an employee of L. H. Knight on February 14, 1949, and was working on *335the job when Mr. Farmer went to work abont a week prior to February 14, 1949; that Mr. Farmer died about 3:45 p. m. on February 14, 1949; that prior to his death he had been working with him on a scaffold which was located about seven feet above the ground; that they had sawhorses on the scaffold and the lumber was placed there while holes were being drilled in it with an electric drill; that just before Mr. Farmer died he (Midgett) Mr. Horn and Mr. Farmer slid a piece of lumber down off the sawhorse, and he and Mr. Farmer then placed the piece of lumber down on the beam where it was to be bolted to the beam; that he then turned around and looked for the helper; that when he looked back Mr. Farmer was falling off the scaffold; that he just rolled off and fell on the ground, landing on his back; that the ground was soft; that he got to him immediately and poured water on him trying to bring him to; that Mr. Farmer had turned black and blue by this time, so he got some more men and laid Mr. Farmer on the floor; that the work Mr. Farmer was doing that day was no more strenuous than what they had been doing all week.”
It appears undisputed that Mr. Farmer had been suffering from hypertension, accelerated heart, other symptoms of a cardiac condition, and a diseased heart as far back as 1947.
Dr. McMillian, on behalf of appellee, testified that in his opinion, Mr. Farmer’s death was caused either by massive cerebral hemorrhage or coronary occlusion and that the work he was doing had no bearing or connection with his death.
The full Commission denied appellant’s claim for compensation and on appeal to the Ashley Circuit Court, the action of the Commission was affirmed. From the judgment is this appeal.
Appellant contends that there was no substantial evidence on which the Commission could have based the order denying compensation and says: ‘ ‘ The sole question is whether death was due to accidental injuries which arose out of, and in the course of, his employment.”
*336We have consistently, through a long line of decisions, adhered to the following rules in construing our ‘‘Workmen’s Compensation Law. ’ ’ The findings of facts by the Commission must be accorded the same force and effect as the verdict of a jury. In other words, if there is any competent, substantial evidence to support the Commission’s findings, we must affirm. The law does not call-for general accident insurance, Burchett v. Tuf-Nut Garment Manufacturing Company, 205 Ark. 483, 169 S. W. 2d 574.
The burden of proof is on the claimant to show that injury or death of the employee was the result of an accidental injury that not only arose in the course of the employment, but in addition, that it grew out of, or resulted from, the employment. An accidental injury may come about by evidence of some unusual strain, effort, or fortuitous happening which might bring about death or injury to the employee either as a direct cause, or by the aggravation of a pre-existing diseased condition from which the employee was suffering at the time of the injury or death. McGregor & Pickett v. Arrington, 206 Ark. 921, 175 S. W. 2d 210. See, also, Schneider on Workmen’s Compensation Text, Vol. 4, § 1328, page 543, which is quoted in full in Baker, et al. v. Slaughter, ante p. 325, 248 S. W. 2d 106, an opinion of this date.
Since the effective date of the initiated Workmen’s Compensation Law (Act 4 of 1948, adopted by the people November 2, 1948, Acts 1949, p. 1420), December 3, 1948, there is no prima facie presumption that the claim comes within the provisions of the law.
The Commission made these findings: “The testimony of Clifford L. Horn and John Midgett, who were working with the decedent at the time of his collapse, was to the effect that the work being done by the decedent at the time of his collapse was of no more strenuous nature than that which 'he had been doing for days prior to his collapse. We do not think the evidence discloses any unusual effort or strain or any fortuitous happening that would constitute an accidental injury which brought about the death of the decedent, either as a *337direct cause or by the aggravation of the pre-existing diseased condition from which the decedent suffered.”
While the evidence is conflicting, we cannot say that there was no substantial evidence, as a matter of law, to support the Commission’s findings, and the judgment of the Circuit Court on appeal. It is not our function to weigh the evidence in these compensation cases. That responsibility had been left to the Commission by the Legislature. Lundell v. Walker, 204 Ark. 871, 165 S. W. 2d 600; H. C. Price Construction Company v. Southern, 216 Ark. 113, 224 S. W. 2d 358 and Ledbetter v. Adams, 217 Ark. 329, 230 S. W. 2d 21.
We recognize that when one is suffering from an admitted pre-existing diseased heart condition, as was the decedent here, death often happens without any intervening trauma or injury, and may come on under ordinary physical activation' or even while resting or asleep.
The judgment is affirmed.
