ECG Cases 47 – ECG Interpretation in Toxicology

In this ECG Cases Dr. Jesse McLaren delves into ECG interpretation in toxicology and the poisoned patient using his HEARTS approach in 7 case examples. Heart rate/rhythm: consider antidotes for brady/tachy-arrhythmias, and for sinus tachycardia consider fluids for vasodilation and benzodiazepines for agitation. Electrical conduction and axis: consider sodium bicarb for QRS > 100 especially if RBBB or terminal rightward shift, and magnesium for QTc> 500. ST/T changes: consider the differential including demand ischemia, associated electrolyte abnormalities, Brugada pattern from sodium channel blockade, and acute coronary occlusion vs vasospasm from cocaine...

Episode 40: Asymptomatic Hypertension

University of Toronto EM Residency program director, Joel Yaphe and cardiovascular EM researcher, Clare Atzema discuss the guidelines, controversies, pearls & pitfalls of Asymptomatic Hypertension in the ED. The literature is thin in this area, and there are many controversies: Does an elevated BP measured in the ED represent true essential hypertension? Do these patients need to be worked up? Are they at risk of serious morbidity and mortality? Should we treat these patients in the ED with antihypertensives? Should we send them home on antihypertensives? and many more......

Episode 5: Renal Colic, Toxicology Update & Body Packers

This Episode is a potpourri of topics - Renal Colic, Toxicology Update & Body Packers. Dr. Lisa Thurgur and Dr. Paul Rosenberg discuss the common presentation of Renal Colic, with perspectives on the mixed evidence for medical expulsive therapy, the overuse of imaging studies and when we need to worry about the patient who presents with excruciating flank pain. Next, Dr. Thurgur gives us an update on the three most important recent advances in Toxicology for emergency physicians - Lipid Emulsion Therapy, Hydroxocobalamin and Insulin therapy for Calcium Channel Blocker toxicity. Finally, Dr. Rosenberg and Dr. Thurgur discuss the 'ins and outs' of body packers. They review the management of both asymptomatic and symptomatic body backers, highlighting common errors and key therapeutic moves to prevent death.
