Wandering Atrial Mat Rhythm

Wandering atrial pacemaker wandering atrial pacemaker is an irregular rhythm.

Wandering atrial mat rhythm.

A rapid irregular atrial rhythm arising from multiple ectopic foci within the atria. You may actually have multifocal atrial tachycardia. Multifocal atrial tachycardia mat is a cardiac arrhythmia caused by multiple sites of competing atrial activity. It is characterized by an irregular atrial rate greater than 100 beats per minute bpm.

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. P waves are present but will vary in shape. In is similar to multifocal atrial tachycardia but the heart rate is under 100 bpm.

These disturbances are usually an indication of lung or heart disease serious metabolic disturbances or toxicity of certain medicines. Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node. Multifocal or multiform atrial tachycardia mat is an abnormal heart rhythm specifically a type of supraventricular tachycardia that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease copd.
