Ischemic QRS prolongation as a biomarker of myocardial injury in STEMI patients
Background Patients with acute coronary occlusion (ACO) may not only have ischemia‐related ST‐segment changes but also changes in the QRS complex. It has recently been shown in dogs that a greater ischemic QRS prolongation (IQP) during ACO is related to lower collateral flow. This suggests that greater IQP could indicate more severe ischemia and thereby…
