This latest “What’s the analysis?” ECG problem on Twitter from Dr. Sam Ghali attracted many on-line guesses from his healthcare colleagues – together with this from a important care nurse practitioner who astutely wrote:
“In at the moment’s healthcare system, she would in all probability be instructed ‘it’s all in your head’ or ‘perhaps it’s best to shed some pounds’.”
Dr. Ghali, an Emergency doctor and affiliate professor on the College of Florida in Jacksonville, later defined the younger affected person’s coronary heart assault to his colleagues:
“This can be a crucial case of a younger girl with nausea, vomiting and extreme ‘heartburn’ signs. The ECG was recorded in triage and needs to be very regarding. Basic, hyper-acute ischemic T-waves. I don’t care that this can be a younger affected person. There’s harm in each single considered one of these ECG leads.”
“This younger girl was discovered to have a 100% ‘wrap round’ mid-Left Anterior Descending coronary artery occlusion – that was opened up and stented within the cath lab.
“Keep in mind this case and by no means ever write off folks with chest ache – particularly girls who could current in a different way than males and are notoriously misdiagnosed or recognized late with worse outcomes. Please assist unfold consciousness, and I promise you’ll make a distinction in these folks’s lives.”
Though most (however not all) Twitter responses appropriately interpreted this ECG (additionally known as EKG) in Dr. Ghali’s casual problem, there was a variety of incorrect guesses that got here from individuals who have graduated from medical college.
Vasospasm acquired plenty of votes – a non-obstructive coronary artery spasm dysfunction known as Prinzmetal’s variant angina – together with one vote for vasospasm attributable to cocaine toxicity. This guess instantly struck a nerve with me as a result of considered one of my longtime readers (age 33 on the time she first wrote to me; she now lives with an implanted defibrillator). She was shocked to be accused by an Emerg doc of being a cocaine person “as a result of I used to be feminine, younger and skinny – barely 100 kilos soaking moist”). He wrote on her medical chart that she had “denied” utilizing the medicine – but that wording itself suggests he suspected she was mendacity to him.
An electrophysiologist (a heart specialist who makes a speciality of coronary heart rhythm issues) guessed this was the ECG of an individual with non-obstructive Takotsubo (“Damaged Coronary heart”) syndrome.
After a doctor guessed SCAD (Spontaneous Coronary Artery Dissection, a coronary heart situation that largely impacts youthful wholesome girls with few if any cardiac danger components), one paramedic began his Tweet response with “I needed to Google SCAD. . .” which is only a tad disturbing, coming from a paramedic. I hope he was in a position to study sufficient from Dr. Google earlier than his subsequent pressing name to the house of an actual SCAD affected person.
One doctor questioned why an Emergency doc would order an ECG for such a younger girl.
One other Twitter response got here from Dr. Lea Merone, a public well being doctor in Australia who wrote: “The responses to this Tweet are why I did my PhD in girls’s power illness.” Her research, known as “I Simply Wish to Really feel Secure Going to a Physician”, printed within the journal Ladies’s Well being Reviews.1
A shocking response immediately quoted the answer from ChatGTP (a synthetic intelligence chatbot) for a digital opinion. The disembodied suggestion mirrored most of the human votes like this:
“Dr. Ghali ought to organize for the affected person to be transferred to a cardiac catheterization lab as quickly as attainable. Immediate remedy might help reduce the extent of coronary heart muscle harm and enhance the affected person’s longterm outcomes.”
Though this was a Twitter train, and never a life-or-death actual world take a look at of diagnostic ability, the vary of incorrect guesses was each shocking and disturbing when you’re a affected person like me, who someway managed to outlive a misdiagnosed “widow maker” coronary heart assault. “You’re in the precise demographic for acid reflux disease!” pronounced the very assured Emerg doc earlier than sending me residence simply 4 hours after symptom onset, feeling terribly embarrassed for having made a fuss over nothing.
He too had graduated from med college.
Granted, ECG interpretation depends on distinctive important considering expertise that enhance with apply if accompanied by a eager enthusiasm for studying, however that apply sometimes arises from ongoing alternatives to apply – that are merely not relevant to all medical specialties – except they’re the form of physician who enjoys enjoying Dr. Ghali’s academic “What’s the analysis?” challenges for enjoyable.
Dr. David Cook dinner, lead writer of a 2020 research on accuracy in decoding ECGs, concluded that, on common, solely half of all ECGs are precisely interpreted, with medical college students having the bottom accuracy and – not surprisingly – cardiologists having the very best at 75 per cent2 . But when Yale heart specialist Dr. Harlan Krumholz reviewed this report for the New England Journal of Medication’s Journal Watch, he wrote:
“This sobering research studies low accuracy within the interpretation of electrocardiograms throughout a variety of teams. Cardiologists did finest, however nonetheless had a excessive prevalence of errors. And coaching had solely a modest impact within the research.”
I wrote right here a few horrific instance of dueling hospital physicians who appeared unable to agree on the interpretation of a affected person’s ECG.
That case concerned the preventable demise of a 70-year outdated girl who had arrived at her native Emergency Division with textbook cardiac signs she’d been experiencing for 5 days. She died there after ready 2 1/2 hours for care whereas Emergency physicians argued with cardiologists about whether or not she was sick sufficient to maneuver to the cath lab. This tragic instance is a case research described by Emergency doctor Dr. Pendell Myers of Charlotte, NC, printed on Dr. Stephen Smith’s ECG weblog (together with skilled ‘what went fallacious?’ analyses of this sort of tragedy).
Diagnostic errors are a major problem in girls, writes Dr. Alyson McGregor, amongst many others. She’s an Emergency doctor at Brown College who wrote the ebook: “Intercourse Issues: How Male-Centric Medication Endangers Ladies’s Well being and What We Can Do About It“. Dr. McGregor defines male-centric medication like this: medical analysis and medical apply based mostly on fashions traditionally designed to work in males, whereas ignoring the distinctive organic/emotional variations between women and men. In truth, she writes that “the male-centric mannequin of drugs is now so pervasive in well being care that many people don’t even notice it exists”.
In the meantime, I’d like to have physicians like Dr. Ghali in each Emergency Division, and much more importantly, instructing each medical college class. I’d like to consider that every one physicians may turn into as expert as Dr. Ghali in appropriately decoding ECGs – and as keen to show colleagues learn how to apply their very own ECG decoding expertise. And naturally I’d like to have physicians who know what Dr. Ghali already understands about girls with coronary heart illness who “could current in a different way than males and are notoriously misdiagnosed or recognized late, with worse outcomes.”
I usually inform my Coronary heart-Good Ladies presentation audiences that I want the Emerg doc who instructed me my ECG was “regular” and misdiagnosed my coronary heart assault as acid reflux disease had bothered to Google my signs (central chest ache, nausea, sweating and ache down my left arm). I’m fairly certain that Dr. Google would have give you just one search consequence: myocardial infarction.
And if I can’t get anyone like Dr. Ghali to interpret my subsequent ECG, perhaps my second selection simply could finish as much as be (gasp!) ChatGTP.
For young women, correct cardiac diagnoses nonetheless stay considerably extra elusive than these our male counterparts will obtain. As one smart med scholar noticed in response to Dr. Ghali’s quiz:
“The ECG comprises two elements that make docs ignore the affected person: ‘younger’ and ‘feminine.’ ”

NOTE FROM CAROLYN: I wrote rather more about cardiac analysis and misdiagnosis in my ebook, A Girl’s Information to Dwelling with Coronary heart Illness (Johns Hopkins College Press). You’ll be able to ask for it at your native library or favorite bookshop (please help your native impartial booksellers) or order it on-line (paperback, hardcover or e-book) at Amazon – or order it immediately from Johns Hopkins College Press (use their code HTWN to avoid wasting 30% off the checklist worth).
Q: Have you ever ever been instructed your ECG was “regular” – when it wasn’t?

Nearly any web page on Dr. Stephen Smith’s ECG weblog. That is the place many ECG hobbyists (as they describe themselves) who love decoding difficult electrocardiograms come to hang around with different consultants for enjoyable. I can solely hope to have an ECG hobbyist decoding my subsequent hospital ECG. . .
