Mat tachycardia treatment.

Multifocal atrial tachycardia mat overview. Multifocal atrial tachycardia mat is an arrhythmia that can be seen in a variety of clinical disorders in addition to a heart rate greater than 100 beats per minute the characteristic electrocardiographic feature is variability in p wave morphology with each unique p wave morphology felt to indicate a different site of atrial origin. It occurs when too many signals electrical impulses are sent from the upper heart atria to the lower heart ventricles. Multifocal atrial tachycardia mat is a rapid heart rate.

Salerno dm anderson b sharkey pj iber c. It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation. Multifocal atrial tachycardia mat is a type of irregular heartbeat in which the heart beats faster than it should. Most commonly seen in patients with severe copd or congestive heart failure.

It s generally seen in children with underlying heart disorders such as congenital heart disease particularly those who ve had heart surgery. Atrial tachycardia may also be triggered by factors such as an infection or drug or alcohol use. An atrial tachycardia is a fast abnormal heart rhythm in which the electrical impulse originates in atrial tissue different than the sinoatrial 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.

Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node. Atrial electrical activation during atrial tachycardias is mostly regular and by definition at a rate faster than 100 bpm although occasionally the rate. Treatment of multifocal atrial tachycardia with verapamil. Intravenous verapamil for treatment of multifocal atrial tachycardia with and without calcium pretreatment.

Atrial tachycardia is the least common type of supraventricular tachycardia. Treatment and or reversal of the precipitating cause may be all that is required for patients with multifocal atrial tachycardia mat. It s one of many types of heart arrhythmias or irregular heart rhythms. What every physician needs to know.
