A side effect described in the literature is lupus. Procainamide is containdicated in AV block 2 and 3. I have incomplete right bundle branch block. I appreciate any helpful response or references.
Lupus is infrequent and usually resolves within a few weeks of stopping the medication.
Procainamide would not aggravate a right bundle branch block, but if you have other underlying conduction system disease it could aggravate that. CHF does not typically occur in patients without underlying CHF to begin with.
