Figure-1: How would YOU interpret this ECG? MY Thoughts on the ECG in Figure-1: When faced with a challenging cardiac arrhythmia — It is a "luxury" to have access to a long lead rhythm strip containing 3 simultaneously -recorded leads. The repeat ECG after this treatment is shown in Figure-4.

Here is her ECG: Regular Wide Complex Tachycardia. Could it be atrial tachycardia with RBBB and LPFB aberrancy? She had an ECG done yesterday!! Here it is: There is sinus with normal conduction, very different from her tachycardia. How do we place Lewis Leads? -- Use the monitor leads (not the 12-lead ECG): 1.

The ECG is rather classic for pulmonary embolism, and indeed this was a large acute PE. This one is far more specific, as it is combined with sinus tachycardia and some T-wave inversion in V1-V3. So this entire ECG is very high probability for PE in a patient with acute dyspnea. and tachycardia, 1.8. incomplete RBBB 1.7

Atrioventricular nodal reentrant tachycardia (AVNRT) results from the presence of a reentry circuit in the AV node. AVNRT is also referred to as paroxysmal supraventricular tachycardia (PSVT) or simply supraventricular tachycardia (SVT). A new approach to the diagnosis of regular wide complex tachycardia.

On initial assessment, she was found to be tachycardic, for which an ECG was ordered and is shown below (no prior available): What do you think? Like the team did in this case, let's start over from the beginning and interpret the entire ECG systematically, beginning with the rhythm. Yes, but not because of the ECG!

Here is her ED ECG: Here is the ED physician's interpretation: IMPRESSION UNCERTAIN REGULAR RHYTHM, wide complex tachycardia, likely p-waves. LEFT BUNDLE BRANCH BLOCK [120+ ms QRS DURATION, 80+ ms Q/S IN V1/V2, 85+ ms R IN I/aVL/V5/V6] Comparison Summary: LBBB and tachycardia are new. This is clearly ventricular tachycardia.

1 Ventricular tachycardia (VT) and ventricular fibrillation (VF) represent the most common initial rhythms for patients presenting to the ED in out-of-hospital cardiac arrest, as well as for patients who develop cardiac arrest while in the ED. Out-of-hospital cardiac arrest is a commonly encountered entity in U.S. Circulation. Am J Emerg Med.
