Researchers at the Mayo Clinic in the US looked at the medical data of 144 patients who had survived a cardiac arrest following emergency treatment. Results found that seven of them, aged between 20 and 42, had consumed an energy drink some time before the life-threatening event, with six requiring electrical shock treatment and one needing manual resuscitation.
Peter Schwartz, of the Centre for Cardiac Arrhythmias of Genetic Origin and Laboratory of Cardiovascular Genetics, in Milan, Italy, wrote in an accompanying editorial: “Critics might say of these findings, ‘it’s just an association by chance’.
“We, as well as the Mayo Clinic group, are perfectly aware that there is no clear and definitive evidence that energy drinks indeed cause life-threatening arrhythmias and that more data are necessary, but we would be remiss if we were not sounding the alarm.”

Okay sure, but no one drinks espresso by the pint. Your typical Starbucks mocha/latte isn’t going to be more caffeinated than the same volume of drip coffee.
Actually I need to correct, was pulling numbers from my head a decade + old when I did the barista thing, it’s more like 80/shot at 1-1.5 oz

So in a regular size beverage yeah it nets out about on par with a regular drip, but it is a lot more condensed. Once decided to make a full mug of espresso, not a recommended idea…
I suppose I should correct myself as well, it’s almost no one who drinks espresso by the pint.
There was a time a decade or so ago where a customer came in to the McDonald’s I was working at at the time and ordered 11 shots of espresso put in one cup. I think that number is correct; the guy had figured out previously that’s how much would fit in a large cup. It took an amusingly long time to make. They were in motorcycle gear, so I hope he was sipping on it on a long haul trip or something. Mercy to the man’s kidneys.
