https://doi.org/10.1016/j.jelectrocard.2020.06.015
Journal of Electrocardiology; Benezet-Mazuecos J, Lozano Rosado Á et. al.

Jun 30th, 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 16th, 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.

Total electrical alternans in a patient with malignant pericardial tamponade.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6058104
BMJ Case Reports; Verlaan D, Veltman JD et. al.

Jul 21st, 2018 - We present a case of a 59-year-old man with acute abdominal pain and progressive shortness of breath. A focused assessment with sonography for trauma scan showed free fluid in the hepatorenal recess and in the recto-uterine recess. Later, due to c...

Study on Mechanical and Electrical Alternans
https://clinicaltrials.gov/ct2/show/NCT01281241

Jan 20th, 2011 - In patients with severe heart failure and aortic valve disease mechanical alternans or pulsus alternans (a condition in which there is a beat-to-beat oscillation in the strength of cardiac muscle at a constant heart rate) is observed. The mechanis...

ECG Challenge: Cardiac Abnormalities After Aortic Valve Replacement
https://www.medscape.com/viewarticle/923698_2

Jan 20th, 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...

ECG Challenge: No Ma'am, It's Not Indigestion
https://www.medscape.com/viewarticle/895569_2

Apr 30th, 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 ...

ECG Challenge: What’s Happening?
https://www.medscape.com/viewarticle/848254_2

Jul 22nd, 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...

Three Questions for 1 Tracing
https://www.medscape.com/viewarticle/772086

Oct 9th, 2012 - Question Questions: 1. What is the rhythm in the latter half of the tracing? 2. What are the 2 wide-QRS complexes in the middle of the tracing? 3. Electrical alternans is present during the tachycardia (note V3-4 especially). Does it imply cardiac...
