This article has identified the defining characteristics of bundle branch and fascicular blocks on the 12-lead ECG. The ability to recognize these ECG patterns is important for ED nurses. Accurate ECG interpretation will assist with appropriate triage and timely intervention for patients. All patients who present to the emergency department with any suspicion of cardiac disease should have an ECG recording taken as soon as practicable. Also, ED nurses should be educated in ECG interpretation to optimize patient outcomes.
