It shows as a change in the p waves on an electrocardiogram ekg.
Wap vs mat.
The wandering atrial pacemaker wap is an arrhythmia that occurs when the natural pacemaker of the heart changes from the sinoatrial sa node to the atrioventricular av node.
This shifting of the pacemaker from the sa node to adjacent tissues is identifiable on ecg lead ii by morphological changes in the p wave.

Wandering atrial pacemaker wap is an atrial arrhythmia that occurs when the natural cardiac pacemaker site shifts between the sinoatrial node sa node the atria and or the atrioventricular node av node.
A rapid irregular atrial rhythm arising from multiple ectopic foci within the atria.
Sinus beats have smooth upright p waves while.
Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node.
A wandering atrial pacemaker is a type of heart arrhythmia.
This is wandering atrial pacemaker typical features for this type of ekg rhythm include the following.
P waves invert when the heart rate slows down and will return to a normal pattern when the heart speeds back up again.
Unlike other atrial arrhythmias such as atrial fibrillation and atrial flutter these heart rhythms are not caused by intrinsic pathological conduction problems and are usually eliminated by correcting noncardiac underlying conditions such as respiratory.
Multifocal atrial tachycardia mat overview.
Heart rate that is normal 60 100 bpm and rhythm that is may be irregular.
In this column the cardiac rhythms known as wandering atrial pacemaker wap and multifocal ectopic atrial tachycardia are considered.
Most commonly seen in patients with severe copd or congestive heart failure.
It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation.
