Wandering atrial pacemaker is an irregular rhythm. In is similar to multifocal atrial tachycardia but the heart rate is under bpm. P waves are present but will vary in shape. Mar 09, · Atrial tachycardia typically arises from an ectopic source in the atrial muscle and produces an atrial rate of beats/min—slower than that of atrial flutter. The P waves may be abnormally shaped depending on the site of the ectopic pacemaker. I. Atrial Tachycardia: What every physician needs to know. An atrial tachycardia is a fast abnormal heart rhythm in which the electrical impulse originates in atrial tissue different than the sinoatrial node.
An atrial tachycardia is a fast abnormal heart rhythm in which the electrical impulse originates in atrial tissue different than the sinoatrial node. Atrial electrical activation during atrial tachycardias is mostly regular and by definition at a rate faster than bpm, although occasionally the rate may oscillate and be slower. Atrial tachycardias are the least frequent form of supraventricular tachycardias in the general population. The mechanisms of the arrhythmia could be abnormal atrial tachycardia rhythm strip,
triggered activity, or reentry that is limited to atrial tissue. Atrial tachycardias are a form of supraventricular tachycardia and can be classified atrial tachycardia rhythm strip
focal or macro-reentrant, depending on their origin and propagation of the electrical impulse.
