Incessant accelerated idioventricular rhythm mimicking preexcitation.
Journal of Electrocardiology; Benezet-Mazuecos J, Lozano Rosado Á et. al.

Jul 1st, 2020 - ECG of patients with Wolf Parkinson White (WPW) syndrome may simulate other entities such as myocardial infarction, ventricular premature complexes, ventricular bigeminy, accelerated idioventricular rhythm, intermittent bundle branch block or elec...

Images of the month 2: Electrocardiographic QRS alternans caused by gastric volvulus.
Clinical Medicine (London, England); McCarron ÉP, Monaghan M et. al.

Nov 17th, 2019 - QRS electrical alternans is characterised by alternating amplitude of the QRS complexes, and is well-documented in cardiac conditions such as pericardial effusion. We describe a case of QRS alternans in a patient with gastric volvulus.

ECG Challenge: Cardiac Abnormalities After Aortic Valve Replacement

Jan 21st, 2020 - The correct diagnosis is sinus tachycardia, left atrial abnormality, and QRS (electrical) alternans, right axis caused by left posterior fascicular block (Figure 2). Figure 2. Courtesy of Dr Podrid. Discussion The rhythm is regular at a rate of 13...

May 1st, 2018 - Discussion The diagnosis is atrial tachycardia, ST elevation myocardial infarction (STEMI) of the anterior wall, QRS (electrical) alternans, and T-wave alternans. (Enlarge Image) Figure 2. Courtesy of Dr Podrid. The rhythm is regular at a rate of ...

'Good Doctor,' Bad Cardiology

Feb 13th, 2018 - While medical dramas can be entertaining and popular, they are often wildly inaccurate when it comes to actual medicine. In this exclusive MedPage Today video, John Higgins, MD, of McGovern Medical School at UTHealth in Houston, goes through the f...

ECG Challenge: What’s Happening?

Jul 23rd, 2015 - Discussion At quick glance, this looks like an electrical alternans. But careful examination, especially of V4, shows that every other beat has a shorter PR interval and a slurred upstroke (delta wave), indicating ventricular preexcitation of ever...

Tall R Waves in the Right Precordial Leads

Feb 14th, 2014 - Explanation The deeply negative initial deflections, which are wide in the inferior leads, certainly suggest an old inferior infarction. Combined with tall R waves in the right precordial leads, these deflections can make one consider an old infer...
