For the Supplementary Data which include background information and detailed discussion of the data that have provided the basis for the Guidelines see https:// For multifocal AT, treatment of an underlying condition is recommended as a first step (Class I). Oral amiodarone may be considered only among patients in whom other antiarrhythmic drugs are ineffective or contraindicated, and catheter ablation is not an option. It occurs when too many signals (electrical impulses) are sent from the upper heart (atria) to the lower heart (ventricles). In postural orthostatic tachycardia syndrome, a regular and progressive exercise program should be considered (Class IIa). Clin Res.

Do not routinely consider catheter ablation for patients with inappropriate sinus tachycardia; restrict catheter ablation for the most symptomatic cases following failure of other therapies and measures. In leads V1–V3 there is regular 2:1 atrioventricular conduction so the ventricular rate is 175 beats/min. The initial treatment of multifocal atrial tachycardia should include supportive measures and aggressive reversal of precipitating causes. The mechanism of the arrhythmia may be delayed afterdepolarizations leading to triggered activity, but this has not been firmly established. 1987. 2016;133;e506-e574. The atrial anatomy is partially reconstructed. Note that the delta wave is positive in lead I and aVL, negative in III and aVF, isoelectric in V1, and positive in the rest of the precordial leads. those with postural orthostatic tachycardia.7 Multifocal atrial tachycardia is another difficult problem because it often occurs in patients with severe cardiopulmonary dis- ease who are not candidates for electrophysiology study. Verapamil/diltiazem and catheter ablation are no longer recommended for inappropriate sinus tachycardia. Catheter ablation is the preferred treatment strategy for almost all patients with symptomatic SVTs, with the exception of pregnant patients in the first trimester and also patients with inappropriate sinus tachycardia, postural orthostatic tachycardia … Atrial electrical activation during atrial tachycardias is mostly regular and by definition at a rate faster than 100 bpm, although occasionally the rate may oscillate and be slower. Note also that the change in the P-wave axis at the onset of tachycardia makes sinus tachycardia unlikely. Asymptomatic patients with preexcited ECG: Consider screening programs for risk stratification. NEW YORK - Catheter ablation is favored for the management of most forms of supraventricular tachycardia (SVT) in adults, according to revised guidelines from the American College of Cardiology/American Heart Association/Heart Rhythm Society (ACC/AHA/HRS). 14(7):998-1005.
