The QRS is wide in B — but the rhythm is irregularly irregular with no sinus P waves — so this most probably represents rapid AFib with an atypical RBBB/LPHB morphology. We now see that QRS morphology in lead II during sinus rhythm is similar to the QRS morphology in lead II during rapid AFib (beats #1-5 in lead II in A).

The patient also has a history of AFib and HFmrEF ( = H eart F ailure with M inimally- R educed E jection F raction ). There is almost always the possibility of exceptions ( ie, prior infarction or cardiomyopathy that might result in a very abnormal baseline tracing ). Why was it Wrong to Think the Rhythm was AFlutter?

He had a h/o ischemic cardiomyopathy and right MCA stroke. As per Dr. Smith — this suggests that despite QRS widening, the rhythm in ECG #3 is AFib with a rapid ventricular response. Given that the patient was asymptomatic from these arrhythmias — there was time to contemplate additional measures.

They had a history of non-ischemic cardiomyopathy (EF 30%), as well as PCI with one stent. In most middle-aged patients with a history of cardiomyopathy, a WCT will usually be VT. Fragmentation suggests scarring (ie, from prior MI and/or cardiomyopathy ). Furthermore, while specific criteria (e.g.

Instead — my thoughts were as follows: The rhythm is sinus , with marked bradycardia and a component of sinus arrhythmia. WPW Cardiac arrhythmias ( especially AFib ).

The chart revealed that the arrhythmia was not new. Atrial arrhythmias ( especially AFib or AFlutter ). It turned out the patient had cardiac amyloidosis. The presenting complaint was cough and fever from mild Covid pneumonia. There was no chest pain — and all troponins were negative. Prolonged QTc interval.

By 1909 ECGs were being used to diagnose cases of arrhythmia; by 1910 to diagnose indicators of a heart attack. Another vendor to watch in this space is Israeli start-up CardiaCare, currently developing a ‘world-first’ closed-loop, neuromodulation wearable for the non-invasive treatment for AFib.

The absence of any wall motion abnormality makes ischemic cardiomyopathy very unlikely. The new onset cardiomyopathy was thought to be due to both drug/alcohol use and to Tachycardia-Induced Cardiomyopathy. Severe right ventricular enlargement and mildly decreased right ventricular systolic function. This is a “ generic ” term.
