What would you see on an ECG with atrial tachycardia?
What would you see on an ECG with atrial tachycardia?
Atrial tachycardia has a more or less regular heart rate > 100 bpm, with narrow QRS complexes but P-waves that do not originate from the sinus node but from another site in the atria.
What is unique about multifocal atrial tachycardia?
Multifocal atrial tachycardia (MAT) is a type of irregular heartbeat in which the heart beats faster than it should. It’s one of many types of heart arrhythmias or irregular heart rhythms. When your heart beats normally, there are between 60 and 100 beats per minute.
What is multifocal atrial tachycardia?
Multifocal atrial tachycardia (MAT) is a rapid heart rate. It occurs when too many signals (electrical impulses) are sent from the upper heart (atria) to the lower heart (ventricles).
What does atrial tachycardia look like on ECG?
As in most SVTs, the electrocardiogram (ECG) typically shows a narrow QRS complex tachycardia (unless bundle branch block aberration occurs). Heart rates are highly variable, with a range of 100-250 bpm. The atrial rhythm is usually regular. (See the image below.)
What does tachycardia look like on ECG?
Sinus tachycardia is recognized on an ECG with a normal upright P wave in lead II preceding every QRS complex. This indicates that the pacemaker is coming from the sinus node and not elsewhere in the atria, with an atrial rate of greater than 100 beats per minute.
What is the classic cause of multifocal atrial tachycardia?
Hypoxia tends to be one of the leading causes of this arrhythmia. Some disorders that may make a patient prone to MAT are pneumonia, Chronic Obstructive Pulmonary Disease (COPD), CHF, lung cancer/failure, and pulmonary emboli (PEs). Other risk factors include coronary artery disease (CAD), diabetes, and sepsis.

What is the rate for atrial tachycardia?
Atrial tachycardia is an abnormally fast heartbeat. It’s the least common type of supraventricular tachycardia. During an atrial tachycardia episode, the heart rate increases to more than 100 beats per minute before returning to a normal heart rate of around 60 to 80 beats per minute.
How do you detect atrial tachycardia?
Atrial tachycardia can sometimes be diagnosed in your physician’s office with an electrocardiogram (ECG or EKG). But when atrial tachycardia is an occasional event, an office ECG may be normal. If this is the case, your doctor may give you an ECG monitor to wear at home that will record your heart rhythm over time.
