Rhythm strip for diagnosis:<\/strong>
\n\"ecg\"
\na) Atrial fibrillation
\nb) Sinus arrhythmia
\nc) Multifocal atrial tachycardia
\nd) None of the above
\nCorrect answer:\u00a0c) Multifocal atrial tachycardia<\/strong>
\nMultifocal atrial tachycardia is defined as three or more different types of P waves occurring at a rate more than 100 per minute.
\nThe nearest differential diagnosis of a multifocal atrial tachycardia is atrial fibrillation (paroxysmal atrial fibrillation in this case). Multifocal atrial tachycardia (MAT) can occur in those with chronic obstructive lung disease [1].
\nMultifocal atrial tachycardia is sometimes called as chaotic atrial rhythm<\/strong> because of the variability in atrial activity. Ikaria study which evaluated the natural history of multifocal atrial rhythms in an elderly outpatient population showed that these rhythms are not associated with excess mortality in the elderly as in multifocal atrial tachycardias of hospitalised patients [2]. The study also showed that multifocal atrial rhythms have a high prevalence in the elderly (6%), with much higher prevalence in those above ninety years (15%).
