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...

ECG Cases 46 ECG in Fever and Infectious Disease

In this ECG Cases blog Dr. Jesse McLaren guides us through 10 cases, driving home the points that sepsis is a common cause of rapid Afib and diffuse ST depression with reciprocal ST elevation in aVR, myo/pericarditis is a diagnosis of exclusion, endocarditis or lyme carditis can cause AV block, PE can cause low grade fever and ECG signs of acute RV strain and that fever can unmask Brugada syndrome...

ECG Cases 45 ECG in Weakness and Neurological Symptoms

In this ECG Cases blog Dr. Jesse MacLaren guides us through 10 cases of patients who present with generalized weakness or acute neurologic symptoms and discusses how to look for ECG signs of dysrhythmias, electrolyte emergencies, acute coronary occlusion, and demand ischemia in patients with generalized weakness and in patients with neurologic symptoms, to consider predisposing factors like LVH; seizure-like activity from cardiac syncope; TIA/CVA embolic sources like atrial fibrillation or LV thrombus; or cardiac complications like stress-induced cardiomyopathy...

ECG Cases 43 – ECG Interpretation in Shortness of Breath

In this ECG Cases blog we look at 10 patients with shortness of breath, and discuss how the ECG can be used to help diagnose cardiac, respiratory and metabolic emergencies. We discover that for STEMI/OMI vs subendocardial ischemia, we should look for STEMI(-)OMI, subacute OMI, and OMI in the presence of LBBB and RBBB, and consider the differential for diffuse ST depression with reciprocal ST elevation in aVR. For RV strain, acute vs chronic, we should look for signs of acute RV strain and chronic pulmonary hypertension. for low voltages we should consider pericardial effusion and other causes, and for hyperkalemia we should look for multiple signs of hyperkalemia as a guide for empiric calcium...
