ICare-ACS (Improving Care Processes for Patients With Suspected Acute Coronary Syndrome): A Study of Cross-System Implementation of a National Clinical Pathway.

Background: Efforts to safely reduce length of stay for emergency department patients with symptoms suggestive of acute coronary syndrome (ACS) have had mixed success. Few system-wide efforts affecting multiple hospital emergency departments have ever been evaluated. We evaluated the effectiveness of a nationwide implementation of clinical pathways for potential ACS in disparate hospitals.

Correlation between vectorcardiographic measures and cardiac magnetic resonance imaging of the left ventricle in an implantable cardioverter defibrillator population.

Background: Measures of vectorcardiographic changes and LV remodelling have been associated with arrhythmic risk. However the correlation between the two modalities is not well characterised.

Methods: We correlated spatial QRS-T angle and ventricular gradient with cardiac MRI derived LV global measures and scar pattern in 66 ICD recipients.
