ECG#1 There is a regular tachycardia with a ventricular rate of about 180 bpm. Smith comment : When there is a regular wide complex tachycardia, first assess whether it is sinus or not. Put shortly is SVT with "Shark Fin STE" and not ventricular tachycardia. An ECG was recorded immediately and is shown below. Is there OMI?

Abstract Introduction Supraventricular tachycardia (SVT) is a common pediatric arrhythmia. Methods and Results This is a multicenter retrospective cohort study from three academic children's hospitals.

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.

It's a very "fun" ECG, with initial ectopic atrial tachycardia (negative P waves in inferior leads conducting 1:1 with the QRSs), followed by spontaneous resolution to sinus rhythm. What About the Tachycardia? Today's regular SVT rhythm could be an ectopic atrial tachycardia ( ATach ) — or an automatic junctional tachycardia.

Multifocal Atrial Tachycardia 2. Failure to follow this advice will undoubtedly lead to overlooking subtle acute MIs — and , it will especially lead to misdiagnosing many cardiac arrhythmias ( as was done in this case ). How can you avoid overlooking this arrhythmia? Sinus with multifocal PACs 3. Sinus with multifocal PVCs 4.

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.
