The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. The Initial ECG in Today's Case: As per Dr. Meyers — the initial ECG in today's case shows sinus tachycardia with bifascicular block ( = RBBB/LAHB ). Sinus Tachycardia ( common in any trauma patient. ).

Wide-complex tachycardia: VT or aberrant, or "other?" A wide-complex tachycardia in an older patient must immediately suggest ventricular tachycardia. Sinus tachycardia with aberrancy was unlikely as the rate was consistently 150 bpm, without spontaneous variation. And indeed the QRS morphology strongly supported VT (e.g.

to 1828 msec. ) — which corresponds to a variation in the rate of sinus bradycardia from 36-to-33/minute. This makes sense given that the underlying rhythm in today's case appears to be marked sinus bradycardia and arrhythmia , with a ventricular escape rhythm appearing when the SA node rate drops below 33/minute.

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. I said I think there is a fixed stenosis in the LAD and the tachycardia and stress caused a type 2 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. He also received insulin with D50, sodium bicarbonate, and kayexalate for hyperkalemia.

As per Dr. Nossen — today's initial ECG ( LEFT tracing in Figure-2 ) shows sinus bradycardia with QRS widening due to bifascicular block ( RBBB/LAHB ). There is marked, diffuse ST segment depression in ECG #1.

There is a regular, wide complex, (mostly) monomorphic tachycardia. The differential of wide, regular, monomorphic tachycardia is: VT or SVT with aberrancy, all +/- hyperkalemia (see diagrams below). Really wide tachycardia = VT or SVT with conduction abnormality + hyperkalemia, until proven otherwise.
