There was concern that the rhythm might represent ventricular tachycardia, so lidocaine was given and one attempt at cardioversion was performed. See our other countless hyperkalemia cases below: General hyperkalemia cases: A 50s year old man with lightheadedness and bradycardia Patient with Dyspnea. A Very Wide Complex Tachycardia.
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?
Here is his ED ECG: There is obvious infero-posterior STEMI. What are you worried about in addition to his STEMI? There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Learning Points: 1.
The ECG shows obvious STEMI(+) OMI due to probable proximal LAD occlusion. This progressed to electrical storm , with incessant PolyMorphic Ventricular Tachycardia ( PMVT ) and recurrent episodes of Ventricular Fibrillation ( VFib ). There was no evidence bradycardia leading up to the runs of PMVT ( as tends to occur with Torsades ).
A prehospital ECG was recorded (not shown and not seen by me) which was worrisome for STEMI. Here was his initial ED ECG: There is sinus tachycardia at a rate of about 140 There is profound ST Elevation across all precordial leads, as well as I and aVL. A near 60 year old male called 911 for increasingly severe fever and SOB.
A prehospital “STEMI” activation was called on a 75 year old male ( Patient 1 ) with a history of hyperlipidemia and LAD and Cx OMI with stent placement. The two cases were considered: Patient 1 was recognized by the ED provider and the cardiologist as having resolved “STEMI”. He wrote most of it and I (Smith) edited. It was stented.
Other than tachycardia, Other than slight tachycardia, vitals were within normal limits (including oxygen saturation). The provider contacted cardiology to discuss the case, but cardiology "didn't think it was a STEMI, didn't think he needed emergent cath." The whole paradigm is literally called "STEMI" vs. "NSTEMI."
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.
ECG is consistent with severe hypokalemia and/or hypomagnesemia causing prolonged QT (QU) at high risk of Torsades (which is polymorphic ventricular tachycardia in the setting of a long QT interval). Polymorphic Ventricular Tachycardia Long QT Syndrome with Continuously Recurrent Polymorphic VT: Management Cardiac Arrest. Is it STEMI?
We have borderline sinus bradycardia with 1 ° AVB and occasional PACs. If this was a tachycardia at a rate of 150, it might appear to be a narrow complex tachycardia, when in fact, it would be a wide complex tachycardia! ECG diagnosis: Borderline sinus bradycardia, 1st degree AVB, RBBB, and occasional PACs.
See many examples of Pseudo STEMI due to hyperkalemia at these two posts: Acute respiratory distress: Correct interpretation of the initial and serial ECG findings, with aggressive management, might have saved his life. But the rate is ~130/minute — which is a bit fast for sinus tachycardia. The patient was treated.
Despite the clinical context, Cardiology was consulted due to concerns for a "STEMI". After initiating treatment for hyperkalemia, repeat ECG showed resolution of Brugada pattern: The ECG shows sinus tachycardia. ST elevation in aVL with reciprocal ST depression in the inferior leads Shock, bradycardia, ST Elevation in V1 and V2.
The shortened PR-interval, specifically, proved to be quite beguiling as it swept crews down a differential diagnosis of intermittent accessory pathway syndrome – insomuch as a “syndrome” of recurrent tachycardia to account for the patient’s symptoms. To which the lead paramedic replied, “Not cardiac; his symptoms are atypical. Is this OMI?
Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. 2) The STE in V1 and V2 has an R'-wave and downsloping ST segments, very atypical for STEMI. A rectal temperature was obtained which read 107.9 Bicarb 20, Lactate 4.2,
My L IST includes the following: i ) LVH with strain; ii ) Ischemia; iii ) Digoxin use; iv ) HypoKalemia and/or HypoMagnesemia; v ) Tachycardia; and , vi ) Any combination of i-thru-v. In my experience, Ive seen U waves not only with low K+/low Mg++ but also in patients with bradycardia, LVH, and sometimes in normal subjects.
ECG met STEMI criteria and was labeled STEMI by computer interpretation. This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern.
There is sinus tachycardia and also a large R-wave in aVR. Drug toxicity , especially diphenhydramine , which has sodium channel blocking effects, and also anticholinergic effects which may result in sinus tachycardia, hyperthermia, delirium, and dry skin. Her temperature was 106 degrees. As part of the workup, she underwent an ECG.
A 12-lead was recorded, showing "STEMI," but is unavailable. There was never ventricular fibrillation (VF) or ventricular tachycardia (VT), no shockable rhythm. Here is a similar case: Collapse, Ventricular Tachycardia, Cardioverted, Comatose on Arrival. Agitation, Confusion, and Unusual Wide Complex Tachycardia.
Within ten minutes, she developed bradycardia, hypotension, and ST changes on monitor. Bradycardia and heart block are very common in RCA OMI. There was indication of parasympathetic overdrive ( the acute inferior STEMI with profound bradycardia and junctional escape ). He told the patient this horrible news.
