A student going through drbeen s ekg interpretation lectuers asked us the difference between mat multifocal atrial tachycardia and pat paroxysmal atrial tachycardia.
Mat vs wap ecg.
Heart rate that is normal 60 100 bpm and rhythm that is may be irregular.
Sinus beats have smooth upright p waves while.
In either case priority rests with identifying and treating the underlying disorder.
Wandering atrial pacemaker wap is an atrial arrhythmia that occurs when the natural cardiac pacemaker site shifts between the sinoatrial node sa node the atria and or the atrioventricular node av node.
A rapid irregular atrial rhythm arising from multiple ectopic foci within the atria.
An electrocardiogram ecg is a diagnostic tool that your doctor can use to measure the electrical activity in your heart.
Most commonly seen in patients with severe copd or congestive heart failure.
Some authors have suggested that patients who have a heart rate less than 100 bpm but who satisfy all other criteria including the clinical profile commonly observed with mat be considered to have multifocal atrial rhythm or multifocal atrial bradycardia if the rate is less than 60 bpm.
Mat stands for multifocal atrial tachycardia.
An ecg reading looks like a series of waves.
The p wave is typically changing shape and size from beat to beat at least three different forms.
Normally the heart rate is controlled by a cluster of cells called the sinoatrial node sa node.
Mat is not a wandering pacemaker.
This is wandering atrial pacemaker.
Multifocal atrial tachycardia mat overview.
This is because clinical implications of mat vs sinus tach with multiple pacs are the same when either rhythm is seen in a patient with one of the clinical settings predisposing to mat.
This shifting of the pacemaker from the sa node to adjacent tissues is identifiable on ecg lead ii by morphological changes in the p wave.
Ekg interpretation practice answer.
Pat stands for paroxysmal atrial tachycardia.
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.
Here is a quick summary of the differences.
There s a peak that.
Ecg showing multifocal atrial tachycardia mat.
Causes mechanisms and treatments.
It is typically a transitional rhythm between frequent premature atrial complexes pacs and atrial flutter fibrillation.
