Is it safe for someone with a right bundle branch block to take the medications elavil/desryl seperate and/or together?

RBBB: Both these medications list cardiac conduction abnormalities, and RBBB is one, as contraindications to their use. I have seen patients with chronic,longstanding RBBB tolerate low dose Elavil in past years. Other antidepressants may be considered in such patients. Your pharmacist or a cardiologist would be better qualified to answer this question,however.
