That is exactly what happened as it has happened before, it is rare, but it does happen. It takes a few seconds sometimes for the body to realize that the heart has stopped or is beating in regula rhythm. When he got up and his heart wasn't pumping like it should or had stopped and then he collapses because of a lack of blood flow to the rest of the body.
I'm not a doctor, but I have been an EMT for 21 years and know a little something about how the body works. We have to know so we can treat patients.
Some of the people you have been arguing with on here are some of the most outspoken people against the vaccine and people I have argued with in defense of the vaccine, and they are even saying that it wasn't the vaccine. You should probably be listening to them if you're not going to listen to me. If they are saying it wasn't the vaccine, that means something.
To say- "That's exactly what happened" automatically disqualifies anything else you might say, because no one knows exactly what happened. You've been an EMT for 21 years? And you know a little something of how the body works.....?
I know a little something of how an EMT works. How many people have you defibrillated? Our department of 1000 personnel had SAED's on every rig and would provide BLS care rapidly on scene. I personally used it more than a dozen times. I've done CPR many, many times- and my paramedic wife many, many more times than I, would take over from the EMT/Fire personnel for Advanced Cardiac Life Support which included the administration of drugs (adrenelin/epinephrine) and 12 lead heart monitoring, external defibrillation, IV administration and intubation on scene and enroute to the ER. I've seen people die from massive trauma of all kinds, MVA's, crushing injuries, gunshots, decapitations, impalements, falls, drownings, electrocutions... you name it--I've seen it. I've had several heart attack victims code right in front of me while I've been bagging them, assisting their breathing until their heart stopped.
When a heart's electrical rhythm is disrupted as you suggest--- and maybe you know this, or at least you should know this, unless you work for some little small town department that doesn't even have a proper ALS response capability.... but yes, it can be disrupted by a sudden blow at a certain time, just as it can be disrupted by a sudden obstruction that blocks the flow of blood-- a myocardial infarction. When arrythymia occurs, whatever the cause, the performance of the heart is compromised. This can be as mild as angina- heart pain, tachycardia or bracycardia (fast or slow heart beating) atrial or ventricular fibrillation, depending upon which chambers of the heart are affected, or in the worst case scenarios-- the heart stops beating entirely-- cardiac arrest.
If you've ever seen someone having a triple A, you know what sudden cardiac death looks like. When the aorta bursts, they get a sudden and intense chest pain, or belly pain and they know that they are dying. They will TELL you they are dying, right there in front of you and there is nothing you can do about it. There is a rapid loss of blood pressure due to the aneurysm and the patient goes into immediate shock, followed by heart arrythymia- usually ventricular fibrillation, which is essentially a heart cavitating because there is a lack of blood volume, like any pump does when there is not enough liquid to fill a chamber. But with AAA, there is no amount of shocking you as an EMT can do to restore normal function of a heart with no blood supply because it's the blood vessel (the aorta) supplying blood to the body and brain that is affected. My whole point is that it's sudden, and fatal.
Similarly, when a person is electrocuted by a high voltage source-- it disrupts the rhythm of the heart (arrhythmia) and can cause v-fib or sudden and complete cardiac arrest. Instantly. I've seen it. This is supposedly most like commotio cordis in that it's not the severity of the blow that matters as much as the electrical impulses of the heart that are disrupted. Here's where I'll agree with you and concede that if the heart goes into v-fib prior to sudden cardiac arrest, there can be a moment of delay before that sudden cardiac arrest as we saw in this incident with Damar Hamlin. He stood up and could well have been in v-fib for those few seconds. A few ineffective seconds of v-fib deprives the body of blood pumping, so you'd get that sudden pressure loss, followed by immediate collapse and cardiac arrest. It was the rapid defibrillation that saved him, and the grace of God-- nothing else.
But that's not the point. McCullough isn't saying that it could not have been a commotio cordis event, and neither am I. Commotio cordis just means disruption of the heart. If our hearts stopped every time someone got a little thump on the chest, it would be a common cause of death, rather than a rare and unusual occurrence. McCullough is simply saying that he has observed an INCREASE in the number of incidents of myocarditis since vaccinations of young, otherwise heathly, athletic males in particular. It's not controversial. Everyone can agree with the FDA and the manufacturers of the mRNA shots themselves that in the week or so after receiving an injection (primary or booster) a person (most critically a male, african american, 16-25 years old) is most likely to have compromised heart functionality due to myocarditis that was induced specifically by the mechanism of action of the shot. They KNOW the shots cause myocarditis-- inflammation of the heart muscle and/or pericarditis- inflammation of the tissue surrounding the heart muscle. It's no longer debatable.
McCullough is saying.... and this is ALL he is saying, is this needs to be looked into.
When an athlete is performing at a high level, with an increased heart rate-- these things matter. With the heart beating rapidly, say at 180 bpm or more as would be expected with a Defensive Safety sprinting during a play--- that blow would have to be timed within milliseconds to electrically disrupt the heart, were that the only cause. But if he had had a recent booster shot (an unknown at this point- and likely to never be known given Pfizer's sponsorship of the NFL and the legal jeopardy if things like this ever came out) he could have had an enlarged heart, already compromised making him MORE susceptible to adverse events like commotio cordis.
