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”.
