Identifying patients with high-risk heart failure (HF) who would benefit from an implantable cardioverter-defibrillator (ICD) remains controversial. A potential marker for arrhythmic sudden death is fragmented QRS (fQRS). fQRS is the notching and slurring of the QRS complex in a 12-lead ECG and it indicates abnormal ventricular depolarisation and myocardial scarring and fibrosis.
Acute LAD occlusion in the setting of Right Bundle Branch Block and Left Anterior Fascicular Block. Case Review: [link] Key features of Right Bundle Branch Block: In general, there is no ST elevation throughout the 12 Lead ECG. RBBB has expected slight ST depression, with T wave inversion, in V1-V3 when discordant to a positive R' wave. A possible normal variant is lateral ST elevation (i.e., I/aVL/V5/V6) with bulky T waves when subsequent to a large, slurred S wave.
The word arrhythmia comes from two Greek words. The first is ‘a-’ which means absence or loss and the second is ‘rhythmos’ which means rhythm. So arrhythmia literally means absence or loss of rhythm. A cardiac arrhythmia therefore means loss of cardiac rhythm. It is however used in medical practice as a description for disturbance rather than absence of heart rhythm.
In this main episode podcast on ED risk stratification and workup of the febrile infant, recorded at the CAEP 2022 Conference in Quebec City with Dr. Brett Burstein and Dr. Gary Joubert, we answer such questions as: Which febrile infants require lumbar puncture? How accurate is procalcitonin in identifying low risk febrile infants? What is the difference between serious bacterial infection (SBI) and invasive bacterial infection (IBI) and why is this important in the work up of the febrile infant

AI is transforming clinical trials—accelerating drug discovery, optimizing patient recruitment, and improving data analysis. But its impact goes far beyond research. As AI-driven innovation reshapes the clinical trial process, it’s also influencing broader healthcare trends, from personalized medicine to patient outcomes. Join this new webinar featuring Simran Kaur for an insightful discussion on what all of this means for the future of healthcare!
Introduction Mineralocorticoid receptor antagonists (MRAs) reduce mortality and morbidity in patients with heart failure and reduced ejection fraction (HFrEF), but are largely underused. We evaluated the frequency, motives, predictors and outcomes of MRA discontinuation in a real-world heart failure population. Methods and results This was a single-centre, retrospective cohort study where medical record-based data were collected on patients with HFrEF between 2010 and 2018.
New onset chest discomfort with demonstrable Hyperacute T waves that went undetected by EMS, EM, and cardiology. Case review presentation: [link] Learning Objectives Hyperacute T waves are disproportionately large in comparison to their paired QRS, and represent Grade I Sclarovsky-Birnbaum ischemia. Diffuse / global ST depression is consistent with subendocardial ischemia (supply-demand mismatch) when maximal in Leads II and V5.

What is POTS? POTS stands for postural orthostatic tachycardia syndrome. In this condition, patients complain when they stand up for a prolonged period of time, they feel very uncomfortable with dizziness, palpitations and tremulousness and therefore they either have to sit or lie down or they risk collapsing. When you examine them, the heart rate can be found to be excessively fast.
Objectives Shift work is associated with myocardial infarction and stroke. We studied if shift work is also associated with incident atrial fibrillation (AF) and if this association differs, depending on sex and age. Methods We studied 22 339 participants (age 37.0±9.8 years, 49% women) with paid work from the third (1986–1987), fourth (1994–1995), fifth (2001) and sixth (2007–2008) surveys of the population-based Tromsø Study, Norway.
It's back to the basics! Take a seat and relax as the maestro, Tom Bouthillet, guides us through a stepwise approach to assessing Left Bundle Branch Block-- especially in the nefarious context of Occlusive Myocardial Infarction.
My name is Sanjay Gupta and in my last video, I decried the over-zealous prescription of medications which may have no or limited benefit for the patient. In this video, I wanted to explore this further with respect to Aspirin which is commonly prescribed for prevention or treatment of heart disease. This video is enigmatically entitled ‘Welcome to the primary Bank of Aspirin’.
