Thank you so very much Doctor, and for the recommendations by yourself and nurse Bridget.
I really appreciate all the help you have given me,
With Kind Regards,
Overall, beta blockers can cause some growth arrest in fetuses, and can slow the heart rate some, though typically not enough to cause the heart to stop or adversely altering hemodynamic function. They are frequently used when the fetus has an arrhythmia, such as one called supraventricular tachycardia. We do have a fair bit of experience with this medication in fetuses, and it is overall reasonably tolerated. I will say that 2-3 weeks of exposure won’t likely cause a problem for your baby. With routine monitoring, it could be stopped if your baby was showing problems with growth, which would be the most likely complication seen. Finally, I wouldn’t necessarily recommend a schedule caesarian section if there isn’t a good medical indication for it.
More importantly, though, I’m not exactly sure why you are being put on a beta blocker for “partial right bundle branch block,” especially when you are asymptomatic. Having not evaluated you, I can’t say for sure what is being seen and what the concerns are. That said, we frequently see what we refer to as incomplete right bundle branch block as a normal variant in pediatric and adolescent patients quite frequently. It typically does not require treatment, unless there are other abnormal findings, such as an atrial septal defect or an arrhythmia.
I do agree with Bridget, our nurse who does the screening for our forum, that you might also get some good assistance in the Pregnancy expert forum. You also might want to post the same question to the adult Cardiology forum, as well.
I think you might do better posting this question in the Pregnancy expert forum. The Pediactric Heart forum is for questions regarding heart issues/problems in children. Good luck
