Inferior hyperacute T waves, which have been added to the 2022 ACC consensus on chestpain as a “STEMI equivalent”[3] 3. J Am Coll Cardiol 2022 4. But are there any other signs of Occlusion MI? Kontos et al.
I assumed it was a patient with acute chestpain. It was a man in his 30s with chestpain. There ARE Signs of a Repolarization Variant: Among the many posts in which we've reviewed cases of repolarization variants — is the May 23, 2022 post. What do you think, Steve? Real or just fake?" What do YOU think?
The patient was a middle-aged female who had acute chestpain of approximately 6 hours duration. The pain was still active at the time of evaluation. See some relevant cases below: Chestpain with anterior ST depression: look what happens if you use posterior leads. mm STE in the posterior leads.
Written by Pendell Meyers A man in his 60s presented with acute chestpain and normal vital signs. Here is his triage ECG: What do you think? The ECG shows massively hyperacute T waves of LAD OMI, plus WPW. V3-V5 also have the depressed HATW takeoff which qualifies them as the rare de Winter subtype of HATWs.
Sent by anonymous, written by Pendell Meyers, reviewed by Smith and Grauer A man in his 40s presented to the ED with HTN, DM, and smoking history for evaluation of acute chestpain. He was eating lunch when he had sudden onset chest pressure, 9/10, radiating to his back, with sweating and numbness in both hands.
No ChestPain, but somnolent. The fact that this is syncope makes give it a far lower pretest probability than chestpain, but it was really more than syncope, as the patient actually underwent CPR and had hypotension on arrival of EMS. Here is the ED ECG (a photo of the paper printout) What do you think?
A 50 year old presented to the emergency department of a remote rural community (where the nearest cath lab is a plane ride away) with one hour of mild chestpain radiating to the back and jaw, and an ECG labeled ‘normal’ by the computer interpretation. What do you think, and how would you manage the patient?
Written by Magnus Nossen with Edits by Grauer and Smith The ECGs in today’s case are from 3 different patients all presenting with new-onset CP ( ChestPain ). All ECGs were recorded by EMS, and transferred to a PCI capable center for evaluation. For 2 of the 3 patients — the cath lab was activated based on the ECG.
A 50-something male with hypertension and 20- to 40-year smoking history presented with 1 week of stuttering chestpain that is worse with exertion, which takes many minutes to resolve after resting and never occurs at rest. At times the pain does go to his left neck. It is a ssociated with mild dyspnea on exertion.
Written by Willy Frick A man in his 50s with history of hypertension, hyperlipidemia, and a 30 pack-year smoking history presented to the ER with 1 hour of acute onset, severe chestpain and diaphoresis. His ECG is shown: What do you think? What do you think? Given the R-R interval = 1160 msecs.
Written by Jesse McLaren Four patients presented with chestpain. 2022 ; 51 : 384 - 387 3. 2022 ; 55 : 180 - 182 6.

Am J Emerg Med.
Written by Pendell Meyers A man in his early 40s experienced acute onset chestpain. The chestpain started about 24 hours ago, but there was no detailed information available about whether his pain had come and gone, or what prompted him to be evaluated 24 hours after onset. 2022 Jan;51:384-387.
I went to the patient's chart: Elderly woman with stuttering chestpain and SOB, and dizziness. For more on Giant T waves — See My Comment at the bottom of the page in the June 22, 2020 and September 19, 2022 posts in Dr. Smith's ECG Blog ). What do you think now? This is a very typical ECG for Hypertrophic Cardiomyopathy.
Whenever a patient does not have chestpain, the pre-test probability of OMI is diminished. Of course SOB, jaw pain, shoulder pain, etc can be a result of OMI, but the pretest probability is less and so you must scrutinize further. Here is the first ED ECG: COMPUTER INTERPRETATION: Electronic Atrial Pacemaker.
Written by Jesse McLaren Two patients in their 70s presented to the ED with chestpain and RBBB. Patient 1 : a 75 year old called paramedics with one day of left shoulder pain which migrated to the central chest, which was worse with deep breaths. Do either, both, or neither have occlusion MI? Vitals were normal.
Written by Jesse McLaren A 50 year old presented to triage with one hour of chestpain, and the following ECG labeled normal by the computer (GE Marquette SL) algorithm. 2022 ; 51 : 384 - 387. What do you think? Theres normal sinus rhythm, first degree AV block, early R wave, normal voltages. Here is her ECG: What do you think?
Written by Jesse McLaren A previously healthy 50 year-old presented with 24 hours of intermittent exertional chestpain, radiating to the arms and associated with shortness of breath. In a previously healthy patient with new and ongoing chestpain, this is concerning for acute occlusion of the first diagonal artery.
Let me tell you about her hospitalization, discharged 1 day prior, but it was at another hospital (I wish I had the ECG from that hospitalization): The patient is 40 years old and presented to another hospital with chestpain and SOB. She had been sitting doing work when she experienced "waves of chest tightness". Sats were 88%.
A 50-something man presented in shock with severe chestpain. The April 17, 2022 post ( Leads V1,V2 misplacement ). The May 24, 2022 post ( LA-LL reversal ). The May 26, 2022 post ( LA-LL reversal ).

Sent by anonymous, written by Pendell Meyers A man in his 60s presented with acute chestpain with diaphoresis. The Importance of the History: As noted above — the onset of chestpain in today's case was acute. He had received aspirin and nitroglycerin by EMS, with some improvement. His vitals were within normal limits.
Case An 82 year old man with a history of hypertension presented to the ED with chestpain at 1211.

Healthy male under 25 years old with a pretty good story for acute onset crushing chestpain relieved with nitro. PEARL: Most patients who present with new chestpain + ECG changes + positive troponin — will not need Cardiac MRI. This was sent to me by a partner: "Curious what you think of this one we had overnight.
My Comment by K EN G RAUER, MD ( 2/22 /2023 ): = Today’s case is an important one, because as per Dr. Smith ( in this patient with new chestpain ) — “The initial ECG is diagnostic of infero-postero OMI.” The presence or absence of ST Elevation is a poor marker with which to describe a myocardial infarction. =
A 50-something presented with acute chestpain. Since this patient presented to the ED — You’ll soon have access to the initial troponin — AND — you can repeat the ECG in short order ( ie, within no more than 10-to-20 minutes if chestpain persists ) — to see if there is serial change. Here is her ED ECG.
We compared outcomes from January 2021 to March 2022 (conventional cardiac troponin I [cTnI]) against outcomes from April 2022 to March 2023 (posthscTnI implementation). The primary outcome was hospital length of stay.
Case submitted by Rachel Plate MD, written by Pendell Meyers A man in his 70s presented with chestpain which had started acutely at rest and has lasted for 2 hours.

Upon questioning patient, he denies having any chestpain or chest tightness of any sort. In the absence of chestpain and negative troponin , it appears less likely that he is having acute coronary syndrome though EKG appears concerning. Pericarditis would be even more unlikely in someone without chestpain.
Because the patient had no chestpain or shortness of breath, they were initially diagnosed as gastroenteritis. But because the patient had no chestpain or shortness of breath, it was not deemed to be from ACS. But because the patient had no chestpain or shortness of breath, it was not deemed to be from ACS.

As we've discussed many times on Dr. Smith's ECG Blog ( See My Comment in the March 28, 2022 post in Dr. Smith's ECG Blog, among many others ) — there is no single ECG finding that is diagnostic of acute PE. Figure-2: ECG findings associated of acute PE ( reproduced from My Comment in the March 28, 2022 post ).

His symptoms of chestpain and shortness of breath were attributed to an asthma exacerbation during exercise.
These were texted to me only with "chestpain." It helps to know that the patient has active chestpain, as Wellen's is a post occlusion (reperfusion) state, with open artery and pain-free.

An 80-something woman who presented with chestpain and dyspnea.
