happy feet,
Certainly electrophysiology has progressed exponetially in both understanding of arrythmias and the technology and tools used for arrythmia treatments in the last 10 years. I would need to know more of what arrythmias you were treating, but a RBBB shouldn't have significant impact on the mapping of the arthmia. Our electrophysilogy section at Cleveland Clinic is outstanding and would be glad to evaluate you.
good luck
