Extreme Axis Deviation Basics
Key Points Definition: Extreme axis deviation (aka “Northwest Axis”) occurs when the QRS axis is between –90° and ±180°. ECG Clue: QRS negative in Lead I QRS negative in Lead…
Navigating a Very Abnormal QRS Axis with a Stepwise Approach
A 44-year-old woman presents to the emergency department with vague complaints about shortness of breath. The following ECG is obtained at triage and brought to you for interpretation:
