Discontinue all negative chronotropic agents, since the risk of torsade is much higher with bradycardia or pauses. As described above by Dr. Smith Pacing in today's case is an effective intervention as doing so prevents the bradycardia and pauses that are likely to precipitate additional episodes of Torsades de Pointes.

RBBB is no longer seen after conversion to sinus rhythm — which supports our suspicion that the intermittent RBBB conduction seen every-other-beat during the tachycardia ( in Figure-1 ) was rate-related. Note that QRS morphology after conversion to sinus rhythm is very similar to QRS morphology of odd-numbered beats during the tachycardia.

Initial ECG in the ED: Presenting ECG : Wide-complex tachycardia at a rate about 200. This is overwhelmingly likely to be ventricular tachycardia, even if only age and medical history are considered. Nevertheless, the widths of both the QRS complex and the RS duration are similar in both the old ECG and the tachycardia.

A 50-something male with unspecified history of cardiomyopathy presented in diabetic ketoacidosis (without significant hyperkalemia) with a wide complex tachycardia and hypotension. Analysis: there is a wide complex tachycardia. This was the interpretation I put into the system: WIDE COMPLEX TACHYCARDIA. It is regular.

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.

See this case, where a patient with BTWI morphology and dramatic EKG changes within minutes is diagnosed with myocarditis: [link] com/2019/07/what-does-this- ecg-with-significant-st.html EKG 3 also has a saddleback morphology in V2, which is only rarely due to OMI. Still, such dramatic changes cannot be overlooked. It was stented.

No more abnormal U-waves == MY Comment, by K EN G RAUER, MD ( 11/18/2019 ): == LOTS of great points regarding use of the ECG in association with electrolyte abnormalities. U waves may also be found in patients with LVH and/or bradycardia , or occasionally as a normal variant. N OTE # 1 — U waves are not specific for hypokalemia!
