You're here for the cats, aren't you? Over 60,000 views for 'Cats as EP, a thread' posted at start of pandemic, by far most views of any of my tweets, which is a little bit sad.

Revisit the thread easily here for CME.

This was the first morning in my life where I could say:
'Did you see that ludicrous display last night?'
and actually follow it up with custom and accurate commentary!!

Driving home from a long day at the hospital.. suddenly thick fog descends.. THEN crazy Alfred Hitchcockian music comes on the radio so I had to slow WAAAYYY DOWN to prevent the impending death the soundtrack was about to imply. #impendingdoom #scarymusic #thickfog #drivesafely

[G. Stuart Mendenhall, MD @GSMedicine]

Thankfully there are no middle schoolers in the hospital. #epeeps

[G. Stuart Mendenhall, MD @GSMedicine]

Closing ceremonies at a most successful #HRX2025, outlining the future of cardiology and EP. Notify your hospital that you will be attending next year's event. Dr. Silva @jennifersilva and @AtulGupta_MD the CMO of Philips.

Dangerous situation, lights going SE on Genesee at N Torrey pines road are unlit (no red), but the other sides are getting green lights. Drivers may think it is four way stop but the other side sees a green light. Reported to dpw.

I asked ChatGPT to finish the limerick:

There once was an EP at Scripps,
Who analyzed electrogram blips.

It answered:
With a signal so neat,
He’d map out the beat,
And decode all the heart's little trips.

Not bad, I suppose. #epeeps

@amytongwu Yesterday was normal but today everywhere outside smells like a campfire in San Diego. Be safe!

If I ever open a bar it will be called 'Chad's Vascor'. In fact, all names of post-medical endeavors will be derived from whimsical Dragon mis-transcriptions.

Welcome to Chad's! There's open seating in the atrium. #EPeeps

[G. Stuart Mendenhall, MD @GSMedicine]

@VintageVolts @vcfederation The only reasonable next step is to ball up a sheet say 'bah' and throw it at the nearest nerd's head.
Be careful, it may be your own.

Ahh the 1980s. We had our old-timey Beagle Brothers software and old-timey Smith Brothers cough drops.

@mikepriceinla @NyahojaSarahFan Also, I seem to recall his son being a subject in one of his flight experiments, perhaps there is a story there :)

[G. Stuart Mendenhall, MD @GSMedicine]

@mikepriceinla @NyahojaSarahFan >Such is the life of a second tier side character.

Second-tier?? Whilst Springfield U may lack the double-Boula prowess of more famous second-tier institutions, Dr. Frink's research has been nominated for several (ig)Nobel Prizes!

[G. Stuart Mendenhall, MD @GSMedicine]

Many #epeeps at #APHRS!
@netta_doc doing @HRSonline TV.
Opportunity to talk with @EmmaSvennberg about visions for the future of ubiquitous rhythm assessment. EP is still such a dynamic field.

[G. Stuart Mendenhall, MD @GSMedicine]

A real koala at #APHRS2024 day one!

Thoughtful keynote on AF progression and patterns by @harry_crijns. Is progression a marker or can ablation consistently interrupt the pathophysiology?

[G. Stuart Mendenhall, MD @GSMedicine]

Congrats to the #HRX2024 moderated / interactive Abstractx presenters!

[G. Stuart Mendenhall, MD @GSMedicine]

@narrowQRS Yes I also didn't see it. It's so odd and now pushes non-professional content and risque stuff, so I also largely stopped using twitter/X. It is quite a sad outcome.
