WebJul 18, 2024 · Excerpt. 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 ... WebJul 11, 2014 · Focal atrial tachycardia (FAT) is an uncommon cause of supraventricular tachycardia in children, which occurs because of an abnormal, nonsinus, atrial focus with enhanced automaticity. 1 – 3 FAT often occurs as an incessant arrhythmia. shropshire ibd pathway

WebWhen incessant tachycardia is present, tachycardiomyopathy may develop. The efficacy of antiarrhythmic drugs for long-term management of atrial tachycardia is poorly defined, but is probably limited. Class IC or class I agents may be used in re-entrant atrial tachycardia, and verapamil, beta-blockers or class IC agents in the focal type. WebFeb 11, 2024 · Procainamide, sotalol, and digoxin are no longer recommended for the acute management of focal atrial tachycardia (AT). Amiodarone, sotalol, and disopyramide are not recommended for chronic suppression of focal AT. Catheter ablation is recommended for recurrent focal AT, especially if incessant or causing tachycardia cardiomyopathy.
