Welcome to Part 1: The Basics Quiz (34 questions)Tests you on the ECG basics: ECG leads and the area of the heart they represent, naming and measuring the QRS complex, locating and measuring the PR and QT intervals, determining the QRS axis, evaluating the P wave, measuring the heart rate, identifying sinus rhythm and more.Some images may take a few seconds to appear.Question #1: Which leads represent the anterior part of the heart?
