- Given the difficulty in diagnosis, sporadic presentation and sparse literature available, the exact incidence and prevalence of paroxysmal AV block is unknown.
- An unpublished study done at Beth Israel Deaconess Medical Centre in collaboration with a cardiology department in the Netherlands found that paroxysmal AV block was most associated with RBBBs followed by LBBBs, intraventricular conduction delays and normal QRS complexes.
- An age presentation of 26-99 years of age, an equal incidence in both men and women and an increased prevalence in older individuals were also seen.
- However, the association between paroxysmal AV block and RBBB is a matter of much debate, as it is not sure whether RBBB causes a direct effect or is a sign seen in an aging population. [1]
- The ISSUE 2 study was characterised by a population of individuals with a high mean age, a history of recurrent syncope beginning in middle or older ages, and frequent injuries probably due to presentation without warning.[2]
