Dr. Jesse McLaren discusses some key aspects of cocaine chest pain ECG interpretation in this month's blog including: Patients with cocaine-associated chest pain require benzodiazepines +/- nitroglycerine for symptom relief, aspirin and ECG to look for signs of occlusion and reperfusion. In patients with chest pain + ST elevation, consider false positive STEMI including early repolarization, LVH and Brugada-pattern. In patients with cocaine chest pain who are STEMI negative, beware STEMI(-)OMI including subtle ST elevation, hyperacute T waves, reciprocal change, and refractory ischemia. For cocaine chest pain patients who's chest pain has resolved, look for reperfusion T wave inversion, as this may put them at risk for reocclusion.

In this month's ECG Cases blog Dr. McLaren explains the PACER mnemonic approach to patients with pacemakers: Pacemaker spike: is it appropriately presence/absent, is there pacemaker-mediated tachycardia (apply magnet) or is there failure to pace (apply magnet to stop sensing, cardio consult)? Aware (sensing): is it normal, is there oversensing (underpacing: apply magnet) or undersensing (treat reversible causes, cardio consult). Capture: if there are pacemaker spikes is there capture, or failure to capture (treat reversible causes, cardio consult). ECG 12 lead: are there signs of hyperkalemia (extra wide QRS, peaked T) or Occlusion MI (Modified Sgarbossa Criteria) that need immediate treatment. Rest of patient: is there a complication of pacemaker insertion related to the pocket (hematoma, infection), lead (pneumothorax, DVT), or heart (pericardial perforation), or is there an emergency unrelated to the pacemaker (eg dehydration, sepsis, GI bleed)...

Takotsubo Syndrome is usually triggered by an emotional or physical stress leading to acute catecholaminergic myocardial stunning. The initial ST elevation phase of Takotsubo Syndrome mimics Occlusion MI, can not be distinguished by patient factors or POCUS findings, and requires immediate angiogram. The subsequent phase of Takotsubo Syndrome has T wave inversion in an apical distribution, which can mimic reperfusion, but often has very deep T wave inversions and a very long QT interval. Takotsubo Syndrome is a retrospective diagnosis of exclusion—with an angiogram ruling out occlusion, a ventriculogram showing apical ballooning, and a follow up echo showing recovery of LV function. Complications of Takotsubo Syndrome include LV failure, apical thrombus, and polymorphic VT from long QT. Jesse McLaren guides us through 10 ECGs to elucidate these important take home points...

I remember when I started practicing emergency medicine a decade and a half ago it seemed that any kid who came to our ED in cardiac arrest died. I know, depressing thought. But, over the past 15 years, survival to discharge from pediatric cardiac arrest has markedly improved, at least for in-hospital arrests. This is probably mostly due to an emphasis on high-quality CPR and advances in post-resuscitation care; nonetheless the more comfortable, knowledgeable and prepared we are for the always scary critically ill pediatric patient, the more likely we will be able to resuscitate them successfully - which is always a huge save.

This is 'A Nuanced Approach to Emergency Management of Hyperkalemia' on EM Cases.

Of all the electrolyte emergencies, hyperkalemia is the one that has the greatest potential to lead to cardiac arrest. And so, early in my EM training I learned to get the patient on a monitor, ensure IV access, order up an ECG, bombard the patient with a cocktail of kayexalate, calcium, insulin, B-agonists, bicarb, fluids and furosemide, and get the patient admitted, maybe with some dialysis to boot. Little did I know that some of these therapies were based on theory alone while others were based on a few small poorly done studies. It turns out that some of these therapies may cause more harm than good, and that precisely when and how to give these therapies to optimize patient outcomes is still not really known...

Congenital Heart Disease Emergencies on EM cases with Gary Joubert and Ashley Strobel.

You might be surprised to learn that the prevalence of critical cardiac disease in infants is almost as high as the prevalence of infant sepsis. And if you’re like me, you don’t feel quite as confident managing sick infants with critical heart disease as you do managing sepsis. Critical congenital heart defects are often missed in the ED. For a variety of reasons, there are currently more children with congenital heart disease presenting to the ED than ever before and these numbers will continue to grow in the future. When I was in medical school I vaguely remember learning the complex physiology and long lists of congenital heart diseases, which I’ve now all but forgotten. What we really need to know about congenital heart disease emergencies is what actions to take in the ED when we have a cyanotic or shocky baby in front of us in the resuscitation room. So with the goal of learning a practical approach to congenital heart disease emergencies using the child’s age, colour and few simple tests, Dr. Strobel and Dr. Joubert will discuss some key actions, pearls and pitfalls so that the next time you’re faced with that crashing baby in the resuscitation room, you’ll know exactly what to do.

Journal Jam 7 - Amiodarone vs Lidocaine vs Placebo in Cardiac Arrest: The ALPS Trial.

In our most popular EM Cases episode to date - ACLS Guidelines Cardiac Arrest Controversies, we boldly stated, that there has never been an antiarrhythmic medication that has shown any long term survival benefit in cardiac arrest. The use of medications in cardiac arrest has been one of those things that we all do, but that we know the evidence isn’t great for. Yet Amiodarone is still in the newest AHA adult cardiac arrest algorithm for ventricular fibrillation or pulseless ventricular tachycarida – 300mg IV after the 3rd shock with the option to give it again at 150mg after that. Anti-arrhythmics have been shown in previous RCTs to increase the rate of return of spontaneous circulation and even increased survival to hospital admission, however none of them have been able to show a decrease in mortality or a favourable neurological outcome at hospital discharge. In other words, there has never been shown a long term survival or functional benefit - which is a bit disconcerting.

But now, we have a recent large randomized, controlled trial that shines some new light on the role of anti-arrythmics in cardiac arrest - The ALPS trial: Amiodarone vs Lidocaine vs placebo in out of hospital cardiac arrest. In this Journal Jam podcast, Justin Morgenstern and Anton Helman interview two authors of the ALPS trial, Dr. Laurie Morrison a world-renowned researcher in cardiac arrest and Dr. Paul Dorian, a cardiac electrophysiologist and one of Canada's leading authorities on arrhythmias about what we should take away from the ALPS trial. It turns out, it's not so simple. We also discuss the value of dual shock therapy for shock resistant ventricular fibrillation and the future of cardiac arrest care.

I had the great pleasure of meeting Dr. Mike Winters on his first ever visit to Canada at North York General's Emergency Medicine Update Conference, where he gave two fantastic presentations. His credentials are impressive: He is the Medical Director of the Emergency Department, Associate Professor in both EM and IM, EM-IM-Critical Care Program co-director and Residency Program Director of EM-IM at the University of Maryland in Baltimore.

Sometimes we are so caught up with the job we need to get done during cardiac arrest that we forget about the important and profound effect that this event has on patients' families. On this Best Case Ever Dr. Winters tells the story of witnessing his grandfather's cardiac arrest, being present in the ED during the resuscitation attempts, and how that experience has coloured his practice. We discuss some pearls on communication with patients' families after death, colour-coded cardiac arrest teams and how to integrate POCUS into cardiac arrest care while minimizing chest compressions.

Traditionally we've run at least 2 troponins 6 or 8 hours apart to help rule out MI and recently in algorithms like the HEART score we've combined clinical data with a 2 or 3 hour delta troponin to help rule out MI. The paper we'll be discussing here is a multicentre/multinantional study from the Canadian Medical Association Journal from this year out of Switzerland entitled "Prospective validation of a 1 hour algorithm to rule out and rule in acute myocardial infarction using a high sensitivity cardian troponin T assay" with lead author Tobias Reichlin. It not only looks at whether or not we can rule out MI using a delta troponin at only 1 hour but whether or not we can expedite the ruling in of MI using this protocol.

Once we've achieved ROSC our job is not over. Good post-arrest care involves maintaining blood pressure and cerebral perfusion, adequate sedation, cooling and preventing hyperthermia, considering antiarrhythmic medications, optimization of tissue oxygen delivery while avoiding hyperoxia, getting patients to PCI who need it, and looking for and treating the underlying cause. Dr. Lin and Dr. Morrison offer us their opinion on the new simplified approach to diagnosing the underlying cause of PEA arrests. We'll also discuss when it's time to terminate resuscitation or 'call the code' as well as some fascinating research on gender differences in cardiac arrest care. These co-authors of the guidelines will give us their vision of the future of cardiac arrest care and we'll wrap up the episode with a third opinion, so to speak: Dr. Weingart's take on the whole thing....
