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...

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.

May 26th, 2014 - IRB Application III: Title: T-Wave Alternans for Acute Coronary Syndrome Patients Objective: Chest Pain is a common and high-risk presenting symptom in the Emergency Department. One of the central challenges Emergency Physicians face is differenti...

Jan 21st, 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...

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 ...

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...

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...

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...
