I agree with the previous poster, but the "truth" (if this is the correct word) in this article is that, yes, adrenaline can kill, if the dose is high enough. If someone inject X mg of adrenaline IV, they will end up with cardiac arrest.

However, the body doesn't work like that. If you survive exercise with heart rate in the 160-180s (or whatever the heart rate is during panic), you will also survive a panic attack. As you know, most people (almost almost all) do. People with existing heart disease can get problems with panic attacks, but that's one of the reasons why they get beta blockers to prevent the heart rate from climbing that high.

5-10% of us can/will end up with panic attacks (some hundred million of the population), and very few die from it. That said, if you have daily panic attacks, that's something that should be treated somehow, as it's very stressful both for body and mind.

You are referring to one man's publicity-grabbing opinion.  He has not published a single paper to buttress his claim.  And not one scholarly article or study anywhere in English documents (or even refers to) this kind of event, except for a couple of medical papers involving a certain group of immigrants several of whom died of night terrors when they believed that someone had put a curse on them.

Do you really wish to believe this sensationalist stuff?
