In 1996 Sgarbossa reviewed 17 ventricular-paced electrocardiograms (ECGs) in acute myocardial infarction (AMI) for signs of ischemia. Several characteristics of the paced ECG were predictive of AMI. We sought to evaluate the criteria in ventricular-paced ECGs in an emergency department (ED) cohort.
In 2005, Orange County California Emergency Medical Services (EMS) initiated a field 12-lead program to minimize time to emergency percutaneous coronary intervention (PCI) for field-identified acute myocardial infarction (MI). As the program matured, “false-positive” (defined as no PCI or coronary artery occlusion upon PCI) field MI activations have been identified as a problem for the program.
