title: Termination and suppression of multifocal atrial tachycardia with verapamil.
abstract: Multifocal atrial tachycardia (MAT) is an ectopic atrial tachyarrhythmia most commonly observed in very ill, elderly patients with hypoxia due to chronic pulmonary or cardiac disease. We have described a patient with recurrent MAT whose paroxysms of arrhythmia were promptly terminated with intravenous verapamil and were ultimately prevented by orally administered verapamil.
