Wandering atrial pacemaker and multifocal atrial tachycardia are examples of atrial rhythm disturbances in which frequent, unpredictable beats arise from different areas of the atria. These disturbances are usually an indication of lung or heart disease, serious metabolic disturbances, or toxicity of certain medicines.
What are the characteristics of a wandering atrial pacemaker?
Wandering atrial pacemaker (WAP) is an atrial rhythm where the pacemaking activity of the heart originates from different locations within the atria. This is different from normal pacemaking activity where the sinoatrial node (SA node) is responsible for each heartbeat and keeps a steady rate and rhythm.
How do you treat a wandering pacemaker?
Treatment of a Wandering Atrial Pacemaker
Because it doesn’t usually cause serious symptoms, you usually don’t need treatment for a wandering atrial pacemaker. But if your chest hurts or your heartbeat is racing, your doctor may treat any underlying conditions you might have.
What is the treatment for wandering atrial pacemaker?
In most cases, a wandering atrial pacemaker doesn’t require treatment. But you will need treatment if the condition is caused by digoxin toxicity. This is a potential side effect of digitalis therapy. Digitalis is a medicine used to treat some heart conditions.
Is wandering pacemaker regular or irregular?
Heart Rhythm
The P waves are related to QRS complexes (P-P interval is constant). Sinus arrhythmia, sinus arrest, and wandering pacemaker are normal rhythm variations. In sinus arrhythmia, the P-P interval is irregular.
Is wandering atrial pacemaker normal?
Wandering atrial pacemaker is similar to multifocal atrial tachycardia except the heart rate is normal ― that is, less than 100 beats per minute. Wandering atrial pacemaker occurs when multiple areas (ectopic foci) within the atrium generate consecutive action potentials that are all conducted to the ventricles.
Is wandering atrial pacemaker benign?
Wandering atrial pacemaker (WAP) is a benign atrial arrhythmia observed in elderly patients suffering from obstructive pulmonary diseases that result from an ischemic heart.
What is the rate of wandering atrial pacemaker rhythm?
Description. Wandering atrial pacemaker (WAP) (Fig. 3.12) is an atrial rhythm with multiple P-wave morphologies (three or more), often occurring in a repetitive pattern at a rate of less than 100 bpm.
