It's common practice in peer-reviewed cardiology publications. Some titles are clearly constructed around the acronym (I guess the cool kids call that a "backronym"). We even cite the abbreviated studies (like PIOPED) in our medical notes, though I'll admit I don't enjoy doing it.

I specifically avoid speaking "like a doctor" around my kids; it induces a cringe like no other when I see teenagers trying to speak like an experienced MD.

That said, this Gianna girl seems well-composed, poetry and all.

I can't find the acronym. Is it in the video? Because I'm not watching a video.

I think this is the title (I had to web-search) https://www.usc.edu/CSSF/Current/Projects/33084.pdf

"EMIT: Does iPad Use in Patients with Implantable Cardiac Rhythm Devices Cause Electromagnetic Interference?"

(EMIT looks intended to be an acronym, but what do the letters stand for?)

You can see it in this picture: http://www.bloomberg.com/image/iZbO1N0jA7eY.jpg

As I commented above, this is usual practice for cardiology publications. And her dad is a cardiology subspecialist.

At a guess, "Electro Magnetic Interference Test".
