Kuralay E, Cingoz F, Kilic S, et al. Treatment of atrial tachycardia depends on the severity of the condition and the factors that trigger it. It occurs when too many signals (electrical impulses) are sent from the upper heart (atria) to the lower heart (ventricles). Circulation. bretylium-1000321 Hazard PB, Burnett CR. Postnatal electrocardiograms were compatible with the diagnosis of multifocal atrial tachycardia or chaotic atrial rhythm. 30(3):301-12. This is the first guideline update for SVT by ESC in 16 years. SVTs have been reported as risk factors for sudden cardiac death in patients with adult congenital heart disease (ACHD). In the setting of hemodynamically stable SVT, vagal maneuvers, preferably in the supine position, or adenosine are recommended. Multifocal atrial tachycardia management mainly consists of treatment of the underlying cause. Multifocal atrial tachycardia is … 77(2):345-51. Chest. Macro re-entrant atrial tachycardia .

Stopping medicines, such as theophylline, which can increase heart rate. These guidelines are summarized in the following sections. Both patients were treated with digoxin and the rhythm gradually reverted to sinus. Treatment of multifocal atrial tachycardia with metoprolol. J Cardiol Cases. Catheter ablation is recommended for recurrent focal AT, especially if incessant or causing tachycardia cardiomyopathy. 279(7):344-9. IV amiodarone is not recommended for preexcited atrial fibrillation. Hemodynamically stable SVT (NOTE: Use caution in those with sinus node dysfunction and impaired ventricular function with a need for chronotropic or inotropic support.

[Medline]. 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). The tachycardic threshold for multifocal atrial tachycardia (MAT) has traditionally been set at 100 bpm, but a review of 60 patients with multifocal atrial arrhythmias found a stronger association between the incidence of COPD exacerbations … Clin Res. Law IH, Alam O, Bove EL, et al. [38]. Philadelphia, PA: Mosby Elsevier Inc; 2012. In leads V1–V3 there is regular 2:1 atrioventricular conduction so the ventricular rate is 175 beats/min. The re-entrant circuit involves a large area of the atrium. Continuous infusion diltiazem hydrochloride for treatment of multifocal atrial tachycardia (abstract). [Medline]. Several changes from the previous guidelines (2003) include revised drug grades as well as medications that are no longer considered, and changes to ablation techniques and indications. Tucker KJ, Law J, Rodriques MJ. [Medline]. An atrial tachycardia is a fast abnormal heart rhythm in which the electrical impulse originates in atrial tissue different than the sinoatrial node. Treatment of multifocal atrial tachycardia with metoprolol. The atrial anatomy is partially reconstructed. 27:823-29. MAT is an uncommon cause of tachyarrhythmia; it is often associated with congestive heart failure and COPD. AF is addressed in the 2014 ACC/AHA/HRS Guideline for the Management of Atrial Fibrillation (2014 AF guideline). In postural orthostatic tachycardia syndrome, a regular and progressive exercise program should be considered (Class IIa). The primary treatment during an episode of atrial tachycardia is considered to be rate control using atrioventricular (AV) nodal blocking agents (eg, … Multifocal atrial tachycardia (MAT), also known as chaotic atrial tachycardia or multifocal atrial rhythm, is a heart arrhythmia primarily observed in old and diseased patients., In hospital setting, the prevalence of MAT has been estimated to be from 0.05% to 0.40%.,, The activation waveform spreads from the inferior/lateral aspect of the atrium through the entire chamber. 900226-overview Atrial tachycardia. Multifocal atrial tachycardia in 2 children. Multifocal atrial tachycardia is typically seen in elderly patients with severe illnesses, most commonly COPD. 133(14):e471-505. Circ J.

Multifocal atrial tachycardia (MAT) is an arrhythmia that can be seen in a variety of clinical disorders [].In addition to a heart rate greater than 100 beats per minute, the characteristic electrocardiographic feature is variability in P wave morphology, with each unique P wave morphology felt to indicate a different site of atrial origin. 1985 Oct. 110(4):789-94.

Hemodynamic and respiratory changes. Outlook (Prognosis) Expand Section. ), Consider IV metoprolol (caution for hypotension) for conversion and rate control, Consider atrial overdrive pacing for conversion of AFL (via esophagus or endocardial), Initial evaluation of SVT: Consider hemodynamic evaluation of structural defect for potential repair, Recurrent atrial tachycardia or AFL: Consider oral beta blockers, Prevention: Consider amiodarone if other drugs and catheter ablation are ineffective or contraindicated, Antithrombotic therapy for atrial tachycardia or AFL: Same as for patients with AF, Avoid use of oral sotalol (increased risk for proarrhythmias and mortality), Avoid use of flecainide in patients with ventricular dysfunction (increased risk for proarrhythmias and mortality), Atrial-based pacing to decrease recurrence of atrial tachycardia/AFL: It is not recommended that a pacemaker be implanted, Consider surgical ablation of atrial tachycardia, AFL, or accessory pathways, Patients planned for surgical repair of Ebstein anomaly: Consider preoperative EP study as a routine test, Patients with SVT planned for surgical repair of Ebstein anomaly: Consider preoperative catheter ablation, or intraoperative surgical ablation of accessory pathways, AFL, or atrial tachycardia, Patients with SVT causing hemodynamic instability: DC cardioversion, Vagal maneuvers, preferably in the supine position, may be considered as first-line therapy, Adenosine may be considered if vagal maneuvers fail, IV metoprolol or propranolol may be considered as a second-line drug if adenosine is ineffective, IV verapamil may be considered if adenosine and beta blockers are ineffective or contraindicated, Patients with tolerable symptoms: Consider no medical therapy, Highly symptomatic patients: Consider metoprolol, propranolol, or acebutolol, Highly symptomatic patients when beta blockers are ineffective or contraindicated: Verapamil may be reasonable; sotalol and flecainide may be reasonable, Highly symptomatic, drug-refractory SVT after the first trimester: Consider catheter ablation, Intravenous (IV) adenosine (class IIa; level of evidence [LOE]: C-LD), Synchronized cardioversion, if IV adenosine is ineffective or not feasible (class I; LOE: C-LD), IV beta blockers, diltiazem, or verapamil (class I; LOE: C-LD), IV adenosine, if the diagnosis is suspected but not established (class IIa; LOE: B-NR), IV amiodarone or ibutilide, if beta blockers, diltiazem, verapamil, or adenosine are ineffective (class IIb; LOE: C-LD), Oral beta blockers, diltiazem, or verapamil (class IIa; LOE: C-LD), Flecainide or propafenone in patients without structural heart disease or ischemic heart disease (class IIa; LOE: C-LD), Oral sotalol or amiodarone (class IIb; LOE: C-LD). The diagnosis of MAT requires the presence of three or more consecutive (non-sinus) P waves with different shapes at a rate of 100 or more per minute. Consider atrial overdrive pacing (via esophagus or endocardial), Consider IV ibutilide for conversion of AFL (Caution: Proarrhythmia may occur in patients with impaired ventricular function.
