The tackle has to hit in a 5 millisecond window to cause commotio cordis. So the odds are 5/1,000 = 0.5% that the timing would be “right.”

I am following your methods and calcs. Good approach.
But in the statement above, you have assumed that the 5 millisecond window occurs with a 1 second timeframe. How often does this 5 ms window occur? Once per second, or once per heartbeat? If the pulse rate is greater than 60, then the 5 ms windows would be closer together. Like twice as often for a 120 heart rate. And what is the instantaneous heart rate in the middle of a play and tackle?
Should this be a part of your calcs?
That’s a good point. I watched a video by a doctor describing the electrical currents of a heartbeat and he pointed out the 5 ms window. He didn’t mention heart rate.
But would it make a difference? Suppose it is a 5 ms window at 60 beats per minute. At 120 bpm, you’d have a 2.5 ms window, but you’d have that window would occur twice as often, right? So wouldn’t the 5 ms window NOT be a function of heart rate?
So then the math indicates this would be even more frequent, yet your calculated/expected casualties not from just NFL nor even all football show that this CC event is much lower and far less likely to occur.
As for me no vax and no more cold nor flu thanks to taking an ounce of prevention since Mar 2020 - just vit C & D and zinc.
Yes the world’s leaders really are as evil as their statements continue to indicate WAKE UP!!!
