WebJul 18, 2024 · Multifocal atrial tachycardia (MAT) is a supraventricular tachycardia with a rapid, irregular atrial rhythm arising from multiple ectopic foci within the atria. This arrhythmia is characterized by a heart rate of greater than 100 beats per minute with organized atrial activity yielding three or more different non-sinus P-wave morphologies in ... WebFeb 24, 2024 · The presence of multiple P wave morphologies indicates multiple ectopic pacemakers within the atria and/or AV junction. If ≥ 3 different P wave morphologies are seen, then multifocal atrial rhythm is diagnosed; If ≥ 3 different P wave morphologies are seen and the rate is ≥ 100, then multifocal atrial tachycardia (MAT) is diagnosed. earth and science lesson
