Pacemaker Rhythms

Atrioventricular Pacemaker Rhythm ECG Interpretation

Atrioventricular Rhythm

This rhythm is easily identified by the conspicuous presence of a pacing spike immediately preceding the P waves and the QRS complexes.
The PR interval is measured from the atrial spike to the ventricular spike. This is also referred to as AV delay.
This “delay” is programmed by the physician during implantation to mimic the natural delay of the PR interval to facilitate the “atrial kick”.

Analyze this tracing using the five steps of rhythm analysis.
