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. Causes of wandering atrial pacemaker are unclear, but there may be factors leading to it…
Pacemaker Rhythms
Common Pacing Modes. AAI – Atrial pacing and sensing. If native atrial activity sensed then pacing is inhibited. If no native activity sensed for pre-determined time then atrial pacing initiated.
Wandering Atrial Pacemaker (WAP) ECG Review
Wandering atrial pacemaker occurs when multiple areas (ectopic foci) within the atrium generate consecutive action potentials that are all conducted to the ventricles. Thus, each QRS complex...
Junctional and ventricular escape rhythms arise when the rate of supraventricular impulses arriving at the AV node or ventricle is less than the intrinsic rate of the ectopic pacemaker. Causes. Conditions leading to the emergence of a …

KEY FEATURES. ESSENTIALS OF DIAGNOSIS. Progressive cyclic variation in P-wave morphology. Heart rate 60–100 bpm. Variation of P-wave morphology, P-P interval, and P-R interval. GENERAL CONSIDERATIONS. This rhythm is …
Multifocal atrial tachycardia
Patients with multiple P-wave morphologies but a normal heart rate (60 to 100 bpm) are considered to have a wandering atrial pacemaker, since the heart rate does not …
