Rate-related (usually tachycardia-dependent) RBBB is common and of no known clinical significance.
Can SVT cause right bundle branch block?
Bundle branch block aberrancy during SVT in the presence of pre-existent contralateral BBB is extremely rare, even in the presence of a His-Purkinje system dysfunction. A functional or anatomical block at one or more levels in the conduction system can cause LBBB.
Is SVT considered heart failure?

What are the effects of RBBB?
Complications. This can slow your heart rate, which can cause fainting and lead to serious complications and abnormal heart rhythms. People who have a heart attack and develop a left bundle branch block have a higher chance of complications, including sudden cardiac death, than do people who don’t develop the condition after a heart attack.
What does RBBB stand for in cardiology?
RBBB stands for Right Bundle Branch Block (cardiology) Suggest new definition. This definition appears very frequently and is found in the following Acronym Finder categories: Science, medicine, engineering, etc.
Can RBBB be reversed?
Like RBBBs, LBBBs are usually diagnosed as “complete” or “incomplete,” however, they are more of a concern to life insurance companies. The septum is normally activated from right to left, but with a LBBB, this pattern is reversed.
