Atrial Pacemaker Rhythm
Description
This rhythm is easily identified by the conspicuous presence of a pacing spike immediately preceding the P wave.
Not all pacing spikes will look exactly the same. They may be below or above the isoelectric line or be partially above and below.
The PR interval is measured from the pacing spike to the beginning of ventricular depolarization.
Practice Strip
Analyze this tracing using the five steps of rhythm analysis.
Compare your answers with the answers on the next slide.
Answers
Rhythm: Regular
Rate: 83
P Wave: upright and uniform with spikes
PR interval: 0.16 sec
QRS: 0.06 sec
Interpretation: Atrial Pacemaker Rhythm with 100% capture
