Wandering Atrial Mat Rhythm

It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation.

Wandering atrial mat rhythm.

Wandering atrial pacemaker wandering atrial pacemaker is an irregular rhythm. Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node. 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. It is characterized by an irregular atrial rate greater than 100 beats per minute bpm.

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. A rapid irregular atrial rhythm arising from multiple ectopic foci within the atria. P waves are present but will vary in shape. These disturbances are usually an indication of lung or heart disease serious metabolic disturbances or toxicity of certain medicines.

In is similar to multifocal atrial tachycardia but the heart rate is under 100 bpm. Multifocal atrial tachycardia mat is a cardiac arrhythmia caused by multiple sites of competing atrial activity. Most commonly seen in patients with severe copd or congestive heart failure.
