ECG Basics: Sinus Rhythm With Complete AV Block and Ventricular Escape Rhythm
This rhythm strip shows a good example of complete (third-degree) AV block with ventricular escape rhythm. It will be easy for your basic students to "march out" the P waves. They are regular at a rate of about 88/min., and they are either visible, or are "hiding" in the QRS complex. The ventricular rhythm is wide and very slow, and completely dissociated from the sinus rhythm.
