I have reflective wpw making me subject to continuous trigeminal pacs. in such cases does a beta blocker do more than suppress uncomfortable symptoms does it add a component of safety?

Yes & Yes...: Eps studies guide therapy as they MAP out the unique anatomy of a person's accessory pathways (ap) and their predilection for re-entrant svt (arrhythmias). That said, chronic use of beta blockers (or verapamil/diltiazem) can be used to prevent these arrhythmias, not just to suppress symptoms. Often class 1c and 1a drugs are also used as they slow conduction, etc. Great question!

It may not: Not sure what reflective WPW is? Wpw refers to an accessory connection between the atrium and ventricle predisposing to svt. There is also increased incidence of af. Theoretically, a b-blocker can result in increased conduction over the connection during af creating potentially very dangerous tachycardia. An electro physiologist can assess your risks.
