ECG cases is a monthly blog by Jesse McLaren (@ECGcases), a Toronto emergency physician with an interest in emergency cardiology quality improvement and education. Each post features a number of ECGs related to a particular theme or diagnosis (with a focus on acute coronary occlusion), so you can test your interpretation skills. We challenge you with missed or delayed diagnosis, those with false positive diagnosis, and those that had a rapid and correct diagnosis. Cases are followed by a quick summary of the literature that relates to the cases, and we bring it home with practice changing pearls that you can use on your next shift.
ECG Cases 13: LVH and Occlusion MI
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?
