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?
ECG Cases 12: RBBB and Occlusion MI
In this ECG Cases blog we look at 7 patients with RBBB and potentially ischemic symptoms. Which had RBBB and occlusion MI?...
ECG Cases 11: LBBB + 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....
