Background Early ventricular tachycardia/fibrillation (VT/VF) in patients with ST-elevation myocardialinfarction (STEMI) has higher morbidity and mortality. This study examines gender-differentiated risk factors and underlying mechanisms for early onset VT/VF in STEMI. vs. 61.0 ± 13.0 vs. 1.70 ± 0.28, P = 0.02
This is a value typical for a large subacute MI, n ormal value 48 hours after myocardialinfarction is associated with Post-Infarction Regional Pericarditis ( PIRP ). Sinus tachycardia has many potential causes. This is especially true for the elderly patient with sinus tachycardia.
Alternatively , it is someone who has an old myocardialinfarction and is now very sick with something else. The patient spontaneously converted back to sinus tachycardia. They agreed that the ECG findings were due only to old MI and tachycardia. Later, I obtained more clinical history. Looks like atrial fibrillation.
Precordial ST depression may be subendocardial ischemia or posterior STEMI. If you thought it might be a posterior STEMI, then you might have ordered a posterior ECG [change leads V4-V6 around to the back (V7-V9)]. Notice there is tachycardia. So there was 3-vessel disease, but with an acute posterior STEMI.
This is ischemic ST depression, and could be due to increasing tachycardia, with a heart rate over 130, but that is unlikely given that the patient is now complaining of crushing chest pain and that there was tachycardia all along. There is widespread ST depression. Figure-1: Comparison of the first 2 ECGs in today's case.
The ECG is diagnostic of occlusion myocardialinfarction (OMI). It definitely does not fulfill STEMI criteria, and I would argue that it would not lead to cath lab activation in most centers. NOTE #1: Sinus tachycardia is not usually seen in an uncomplicated acute MI. To the uninitiated — this ECG may appear normal.
There is sinus tachycardia. Sinus tachycardia, which exaggerates ST segments and implies that there is another pathology. I have always said that tachycardia should argue against acute MI unless there is cardiogenic shock or 2 simultaneous pathologies. Here is that ECG: What do you think? See Table for diagnostic utility.
There is sinus tachycardia. Because of the high troponin, echocardiography was done and showed a wall motion abnormality in the anterior, anterolateral, and apical walls, consistent with LAD myocardialinfarction. The possibility of anterior STEMI was not noticed during patient care. The QTc is 462 ms. It was stented.
This has been termed a “STEMI equivalent” and included in STEMI guidelines, suggesting this patient should receive dual anti-platelets, heparin and immediate cath lab activation–or thrombolysis in centres where cath lab is not available. aVR ST segment elevation: acute STEMI or not? aVR ST Segment Elevation: Acute STEMI or Not?
He denied any known medical history, specifically: coronary artery disease, hypertension, dyslipidemia, diabetes, heart failure, myocardialinfarction, or any prior PCI/stent. It doesn’t meet any conventional STEMI criteria, but there is patently obvious increased area under the curve. No appreciable skin pallor. Is this OMI?
ng/mL (ULN = 0.030 ng/mL) , diagnostic of myocardial injury. The "criteria" for posterior STEMI are 0.5 Acute myocardial injury: Is it myocardialinfarction, or perhaps myocarditis? Is it STEMI or NonSTEMI? The troponin I returned at 4.1 mm STE in one lead. There is zero ST Elevation. This includes: 1.
The Queen of Hearts correctly says: Smith : Why is this ECG which manifests so much ST Elevation NOT a STEMI (even if it were a 60 year old with chest pain)? In addition to sinus tachycardia, the only abnormalities listed by the computer were "low voltage, precordial leads" and "anteroseptal infarct, old.Q Physician: "No STEMI."
ng/mL This single initial troponin at this level, in the context of chest pain, is high enough to be diagnostic of acute myocardialinfarction. Thus, Wellens' syndrome should be thought of as a transient OMI or transient STEMI. Transient STEMI is at high risk of re-occlusion. Her initial cTnI returned at 0.25
The important point for our purposes is that they do no represent myocardialinfarction. T-wave inversions and dynamic ST elevation Tachycardia, hyperthyroid, and ST elevation. Anterior STEMI? Dr. Smith note: I wouldn't necessarily consider this ENTIRELY "benign." What is it? Activate the Cath Lab?
Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. 2 The astute paramedic recognized this possibility and announced a CODE STEMI. myocardialinfarction), arrhythmias, valvular pathology, shunts, or outflow obstructions.
Cardiac Troponin Changes to Distinguish Type 1 and Type 2 MyocardialInfarction and 180-Day Mortality Risk. In such cases, it is common for tachycardia to exaggerate the ST Elevation And, in fact, there was no new acute MI at this visit - troponins did not rise again. Murakami M. Acute Cardiovascular Care 2014;3(4):317-325.
Here is his ED ECG: There is obvious infero-posterior STEMI. What are you worried about in addition to his STEMI? Comments: STEMI with hypokalemia, especially with a long QT, puts the patient at very high risk of Torsades or Ventricular fibrillation (see many references, with abstracts, below). There is atrial fibrillation.
Automatic activity refers to enhanced pacemaking function (typically from a non sinus node source), for example atrial tachycardia. The receiving emergency physician consulted with interventional cardiology who stated there was no STEMI. Is there STEMI? The patient continued having chest pain. Do not treat AIVR. Moffat, M.
It was read by the treating physician and the overreading cardiologist as "Paced, no STEMI." Immediate and early percutaneous coronary intervention in very high risk and high risk non-ST segment elevation myocardialinfarction patients. Did YOU Notice that the underlying rhythm in Figure-1 appears to be atrial tachycardia?
The axiom of "type 1 (ACS, plaque rupture) STEMIs are not tachycardic unless they are in cardiogenic shock" is not applicable outside of sinus rhythm. 2) Tachycardia to this degree can cause ST segment changes in several ways. Is that an obvious STEMI underneath that rhythm? If I fix the rhythm will the ST changes resolve?
Clin Chem [Internet] 2020;Available from: [link] Smith mini-review: Troponin in Emergency Department COVID patients Cardiac Troponin (cTn) is a nonspecific marker of myocardial injury. In normal times, the most common use of cTni is in diagnosing, or ruling out, acute myocardialinfarction (AMI, a subcategory of acute myocardial injury.
When total LM occlusion does present with STE in aVR, there is ALWAYS ST Elevation elsewhere which makes STEMI obvious; in other words, STE is never limited to only aVR but instead it is part of a massive and usually obvious STEMI. All are, however, clearly massive STEMI. This is her ECG: An obvious STEMI, but which artery?
The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. Troponin T peaked at 38,398 ng/L ( = a very large myocardialinfarction, but not massive-- thanks to the pre-PCI spontaneous reperfusion, and rapid internvention!! ). The below ECG was recorded. Inotropic medication was continued.
There is sinus tachycardia (do not be fooled into thinking this is VT or another wide complex tachycardia!) Code STEMI was activated. A man in his 80s with chest pain What, besides large anterior STEMI, is so ominous about this ECG? She was alert and oriented and hypotensive with initial BP 70/50. Eur Heart J.
There is an obvious inferior STEMI, but what else? Besides the obvious inferior STEMI, there is across the precordial leads also, especially in V1. This STE is diagnostic of Right Ventricular STEMI (RV MI). In fact, the STE is widespread, mimicking an anterior STEMI. EKG is pictured below: What do you think?
His father and brother both died of myocardialinfarction at ages 61 and 45, respectively. pre-existing, stable atherosclerosis) amidst any state of global duress – to include hypertension, hypoxia, tachycardia, hypotension, sepsis, and GI bleed, for example. STEMI was activated and the patient went to Cath on arrival.
She had this ECG recorded: Obvious massive anterior STEMI She was quickly brought to the critical care area and the cath lab was activated. Here is the ECG at 25 minutes: Terrible LAD STEMI (+) OMI So a CT scan was done which of course showed a normal aorta. This time the Queen of Hearts interpreted: No STEMI or Equivalent.
This OMI went unrecognized and, had the artery not re-perfused by itself, the patient could have suffered a very large myocardialinfarction. The Queen of Hearts AI model confidently identifies the first ECG in today's case as occlusion myocardialinfarction (OMI HIGH confidence). He was diagnosed with NSTEMI.
This ECG was recorded: It is difficult to appreciate P-waves, but I believe this is sinus tachycardia. It is correct that he did not have chest pain, but we must remember that fully 1/3 of full blown STEMI do not present with chest pain. They made a final diagnosis of type II myocardialinfarction. He was put on BiPAP.
The paramedics diagnosis was "Possible Anterolateral STEMI." More proof that a huge STEMI may have normal or near normal initial troponin. Taken together, these findings suggest an ongoing extensive antero-lateral STEMI. I don't know what the device algorithm interpretation stated. The final angiographic result is very good.
ECG met STEMI criteria and was labeled STEMI by computer interpretation. J waves can also be induced by Occlusion MI (5), STEMI mimics including takotsubo and myocarditis complicated by ventricular arrhythmias (6, 7), and subarachnoid hemorrhage with VF (8). Take home : Not all STEs are STEMIs or OMIs. What do you think?
The authors describe a case with some features in common with our patient -- a stressful event followed by a stress cardiomyopathy/acute myocardialinfarction overlap syndrome. Acute myocardialinfarction: an uncommon complication of takotsubo cardiomyopathy. Acute myocardialinfarction triggered by emotional stress.
