In all my years as a Paramedic in Detroit, I had only one on-site diagnosed via telemetry sent to the hospital of Cardiac Tamponade.
2 men were arguing in a bar. They both were very drunk. They stated fist fighting, then one guy kicked the other in the chest.
The man kicked fell and while trying to get back up, collapsed.
We arrived in approx. 5 minutes after the patient fell.

The football player reminded of that run.
My patient was DOA.
Were those 2 guys wearing protective padding though? And there was no kicking involved…so your story doesn’t apply.
