"WebWandering 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 … " - Multiple p wave morphology

WebWhat causes the inverted P wave morphology found with junctional rhythms? A. Electrical impulses are coming from the SA node, causing repolarization. B. Electrical impulses are coming from areas of multiple ectopic foci. C. Electrical impulses are coming from the AV node, causing atrial depolarization to flow retrogradely. D. Web17 dec. 2012 · The P wave in II is pyramidal in shape with somewhat rounded apex. Its limbs are smooth with no irregularities. The duration of P wave is 0.08-0.10 sec, but is no greater than 0.11sec. The maximal normal amplitude is 2.5mm, but the normal P wave is usually no greater than 2 mm. THE P WAVE FORM IN LEAD V1.
