How do you treat Aberrancy SVT?
How do you treat Aberrancy SVT?
If SVT with aberrancy, treat with IV adenosine (vagal maneuvers). For irregular WCTs, if atrial fibrillation with aberrancy, consider expert consultation; control rate. If pre-excited atrial fibrillation (AFIB + WPWS), expert consultation is advised. Avoid AV nodal blocking agents, consider amiodarone.
How is SVT managed?
Valsalva maneuvers are effective in terminating SVT in hemodynamically stable patients. Intravenous adenosine, verapamil, and diltiazem are effective in acute termination of SVT. Beta blockers (metoprolol, atenolol, propranolol, and esmolol) are effective in acute termination of SVT.
What is supraventricular tachycardia with Aberrancy?
Any tachycardic rhythm with a left or right bundle branch block that is NOT ventricular tachycardia is considered “supraventricular tachycardia with aberrancy”.
What causes Aberrancy?
Aberrant conduction occurs when the length of the cardiac cycle is changed without a compensatory change in the length of the refractory period. This is explained by the changes of the refractoriness in the His-Purkinje system related to changes in the RR interval.
Are pacemakers used for SVT?
An antitachycardia pacemaker was implanted in 37 for SVT; in one for ventricular tachycardia that could also be used to terminate SVT; in one SVT could be terminated with an activity rate variable pacemaker; and in one a DDD pacemaker was used for prevention and termination of SVT.
What does Aberrancy mean on ECG?
Aberrant ventricular conduction is a common electrocardiographic (EKG) manifestation that occurs when the supraventricular electrical impulse is conducted abnormally through the ventricular conducting system. This results in a wide QRS complex that may be confused with a ventricular ectopic beat.
Does SVT require anticoagulation?
As it currently stands, a detailed discussion of anticoagulation is omitted from the SVT guideline, which simply references the AF guideline, requiring the reader to search out another document for specific recommendations.

What’s aberrant conduction?
Aberrant conduction occurs when the length of the cardiac cycle is changed without a compensatory change in the length of the refractory period.
