ECG Cases 18 – ST DEPRESSED Mnemonic and Occlusion MI
In this ECG Cases blog we look at 10 patients who presented with potentially ischemic symptoms and ST depression. Which had occlusion MI?
In this ECG Cases blog we look at 10 patients who presented with potentially ischemic symptoms and ST depression. Which had occlusion MI?
In this ECG Cases blog we look at 10 patients who presented with ST elevation, and review the differential diagnosis of ST elevation using the ELEVATIONS mnemonic. Which had occlusion MI?
In this ECG Cases blog we examine 6 patients who presented with poor R wave progression, and the LATE mnemonic for the differential...
8 patients presented with ECGs showing a tall R wave in V1. What was the diagnosis? Jesse MacLaren reviews ECG interpretation of a tall R wave in V1 in this month's ECG Cases...
9 patients presented with potentially ischemic symptoms and Q-waves. Which had Occlusion MI? What is the differential diagnosis of Q-waves? How can one distinguish MI vs LV aneurysm on ECG?...
LVH produces secondary repolarization abnormalities that can mimic STEMI. Signs of occlusion MI in patients with LVH include: new Q waves/loss of R waves, disproportionate and dynamic ST elevation (or ST depression from posterior MI), and hyperacute T waves. In this ECG Cases blog we look at 6 patients who presented with potentially ischemic symptoms and LVH on their ECG. Which had an acute coronary occlusion?
In this ECG Cases blog we look at 7 patients with RBBB and potentially ischemic symptoms. Which had RBBB and occlusion MI?...
In ECG Cases 11 - LBBB + Occlusion MI Jesse McLaren runs through 5 patients who present with potentially ischemic symptoms and LBBB and explains the evolution of decision making for cath lab activation criteria. The two most important points are that we should always use the Smith-modified Sgarbossa Criteria to identify occlusion MI in the patient with ischemic symptoms and LBBB, whether old or new, and that those with refractory ischemia and hemodynamic instability from suspected occlusion MI require cath lab activation regardless of the ECG....
Which of the following 9 patients had hyperkalemia? Can you estimate how high their serum potassium was based on the ECG? Jesse MacLaren guides us through 9 ECGs underscoring the fact that while the ECG cannot rule out hyperkalemia, significant hyperkalemia often produces ECG changes in the heart rate (bradycardia, junctional rhythm), electrical conduction (PR prolongation or loss of P waves, QRS prolongation, pacemaker delays), and ST/T waves (Brugada phenocopy, peaked T waves that are narrow/pointy) that can be easily recognized. He suggests when you might pull the trigger on giving empiric calcium treatment based on the ECG finding in this month's ECG Cases...
In this ECG Cases blog we look at 6 patients who presented with cardiorespiratory symptoms, possibly from COVID and illustrate the dangers of anchoring, being hypervigilant for cardiovascular complications, and why testing for COVID in patients being admitted for ACS is important...
