ECG Changes of Hyperkalemia

17 Apr
April 17, 2014

Heart and ECGHyperkalemia is an electrolyte abnormality seen in the emergency department as well as in hospitalized patients and it can be associated with adverse clinical outcomes and death if not treated appropriately. It is important to remember that the electrophysiologic effects of hyperkalemia are directly proportional to both the absolute plasma potassium and its rate of rise. However, neither the ECG nor the plasma potassium alone are an adequate index of the severity of hyperkalemia, and therefore providers should have a low threshold to initiate therapy. Classic teaching of the chronological ECG changes of hyperkalemia include:

  1. Peaked T waves
  2. Prolongation of PR interval
  3. Widening QRS Complex
  4. Loss of P wave
  5. “Sine Wave”
  6. Asystole

From Hippocrates to Osler to FOAM

FOAM LogoAs many know Free Open Access Med(ical Ed)ucation (FOAM) is a concept that was developed in June 2012 at a pub in Ireland. Since its creation FOAM has developed into a collection of constantly evolving, collaborative, and interactive resources and tools with one main objective…to make the world a better place. At the heart of FOAM is the philosophy that high-quality medical education should be free and accessible to all who care for patients and to those who teach the art and science of medicine. Recently, I watched a video from the 2013 Social Media And Critical Care (SMACC) Conference given by Joe Lex that made me realize although the acronym only came into being recently, maybe the concept had historical origins (From Hippocrates to Osler to FOAM).

Safe ApneaPreoxygenation and apneic oxygenation are key in emergency airway management, prevention of desaturation, and very important to patient safety.  One of the best papers I have ever read on this was written by Scott D. Weingart (@emcrit) and Richard M. Levitan (@airwaycam) in the Annals of Emergency Medicine in March 2012. This article reviewed techniques in preoxygenation and peri-intubation oxygenation in adult patients requiring tracheal intubation.  Read more →

Social Media And Critical Care (SMACC)This year I was fortunate enough to attend the Social Media And Critical Care (SMACC) conference from Mar 19th – 21st, 2014 at the Gold Coast Australia, also known as SMACCGOLD.  SMACC is a modern, academic meeting, mixed with on-line technologies to deliver innovation in education in the fields of emergency medicine and critical care. This conference addresses important clinical issues in a format that is energetic, cutting edge, and yet reputable. So what did I learn?  Well, more than I can put into one post, but some of the highlights are listed below. Read more →

REBEL Reviews Now an App by AgileMD

March 19, 2014

REBEL EM AgileMD LogoI am happy to announce that REBEL Reviews will now be an app by AgileMD, and can be found at REBEL Reviews on AgileMD.  REBEL Review cards started as my notes reviewing for board exams and useful clinical content on my rotations as a resident. They had been archived on the blog under REBEL Reviews, but required the internet to access. Now, once downloaded from electronic devices (iPhone/iPad, Android), the cards can be accessed on your mobile device without requiring internet access. The purpose of the cards is to take different board review topics and clinical content, remove the fluff, and consolidate the information into useful high-yield charts. This will remain a FREE resource. Read more →
