Bunny ears showed up on my EKG. I had also an echo cardiagram that showed my heart was good and operating properly with valves. Blood pressure in and out of heart and everything was normal. My doctor indicated it is nothing to worry about and tried to explain. I am not sure exactly what it means and if I should be worried.
A complete right bundle branch block (“bunny ears”) is quite common. In some people, it’s present from birth and they do quite well. While a heart with a right bundle branch block doesn’t beat quite as efficiently as one with otherwise normal conduction, it’s good enough for you to lead a long, normal, active life. Don’t worry about it.

Muito obrigado pelas suas amáveis palavras. Eu posso publicar um livro no futuro, mas agora me contento em apenas ensinar. Felicidades de Houston, Texas.
Question as to thought of “incomplete” RBBB. Situation of QRS <120, no slurring/widening of s wave in laterals, but V1 pattern is a variant, usually rSr'. The statement offered is one of incomplete RBBB but that the left bundle conducts normally to the ventricles. Is there any actual delay in the right bundle?
There IS a conduction delay in the right bundle branch if the “incomplete RBBB” is between 0.10 and 0.12 seconds. However, pay more attention to the width rather than the rSr’ morphology. The rSr’ pattern is very common and can be quite normal in many people. We used to call it a “cristal” (no, I spelled it correctly!) pattern because it represented a depolarization wave that ended up in the right ventricular outflow tract near the “crista interventricularis.” Most adults end the cardiac depolarization in the left basal lateral area, but younger people (less than 40 years) often end the depolarization in the right ventricular outflow tract area. That is why you occasionally see a small S wave in V5 and V6 and occasionally Lead I (though not the typical “wide, slurred S of RBBB). You can also get this pattern if you put the V1 and V2 electrodes a bit too high on the chest wall.
Right bundle branch conduction delay is often manifested by nothing more than a loss of S wave depth in V1 – without any rSr’.
It’s very interesting reflection, specially to confront the left ear with the right one. The correlation between the size of the ears and the incidence of the ventricular arithmia is amasing. Thank you.

Thank you. I just found your reply.

Hi Mark…
There IS a conduction delay in the right bundle branch if the “incomplete RBBB” is between 0.10 and 0.12 seconds. However, pay more attention to the width rather than the rSr’ morphology. The rSr’ pattern is very common and can be quite normal in many people.

Hope this helps!
