2019 Echocardiogram Tachycardia

EKG with paced complexes shown below shows much narrower QRS complex and echocardiogram showed improved LV systolic function primarily due to improvement in LV dyssynchrony. (J Even with tachycardia and a paced QRS duration of ~0.16 J Am Coll Cardiol. 1 for a rate ~75/min 1. 2 for ~85/min and 1. 3 for ~100/minute ).

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.

A rapid echocardiogram was performed, revealing an ejection fraction of 20% with thinning of the anterior-apical walls. While the initial impression might not immediately suggest ventricular tachycardia (VT), a closer examination raises suspicion. The initial troponin T level was measured at 30 ng/L. What is the rhythm?

Elevated troponins prompted an echocardiogram — which revealed an apical wall motion abnormality (WMA). NOTE #1: Sinus tachycardia is not usually seen in an uncomplicated acute MI. Patient #1 in today's post did not get expert ECG interpretation. As a result — the heart rate of ~115/minute in ECG #1 is a worrisome finding.

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.

Here is his 12-lead: There is a wide complex tachycardia with a rate of 257, with RBBB and LPFB (right axis deviation) morphology.

From afar, there is gross tachycardia, cadence irregularities, and narrow QRS complexes that may, or may not, be Sinus in origin; and finally – a cacophony of wide complexes that might very well be ventricular in origin. McLaren : We’ve answered the first question – Sinus Tachycardia with episodic runs of wide QRS (RBBB morphology) and PVC’s.
