What I learned:
From what I can see, about
25% the population has this condition to some degree."The foramen ovale is a small hole located in the atrial septum that is used during fetal circulation to speed up the travel of blood through the heart. When in the womb,a baby does not use it's own lungs for oxygen-rich blood, it relies on the mother to provide oxygen rich blood from the placenta through the umbilical cord to the fetus. Therefore, blood can travel from the veins to the right side of the baby's heart and cross to the left side of the heart through the foramen ovale and skip the trip to the baby's lungs."
Anti-coagulants may be necessary to prevent clots from occurring, which seems to be a possibility in some with this condition.
IRBBB:This community-based study shows that the prevalence of IRBBB and RBBB is two to three times higher in men than in women...... IRBBB by itself is not associated with any clinically relevant adverse outcome. Our results indicate that the finding of an RBBB—unlike IRBBB—in the ECG of a person without known cardiac disease should alert physicians to more careful patient evaluation and follow-up.
In English, Incomplete Right Bundle Branch Block is not associated with bad outcomes.
Anyone with either or both condition should follow up with their doctor, having both is more complicated than one, even more incentive to keep periodic visits with the doctor. Ask him/her about
anti-coagulants, diet, weight, exercise, etc. For me, having these conditions would be an incentive to keep weight down as I age and to be careful with dietary fats and cholesterol as instructed by my doctor.
