Abstract:Asymptomatic bradyarrhythmias involving sinus node dysfunction and atrioventicular
blocks are frequently noted in clinical practice. Its prevalence is expected to rise as devices that are
developed for monitoring cardiac rhythm for longer duration become more widely available. Episodes
of bradyarrhythmia that are asymptomatic are considered to have a benign course compared
with those that cause symptoms and do not necessitate further treatment. However, in certain cases,
they can be a harbinger of future symptoms or cardiac manifestations of systemic diseases. The
evaluation and risk stratification of individuals presenting with asymptomatic bradyarrhythmias is
important not only for preventing implantation of unnecessary permanent pacing devices but also
for reducing significant morbidity by implementing proper treatment as required. In this article, we
will review the current evidence on the pathophysiology, diagnosis, evaluation and management of
patients with asymptomatic bradyarrhythmias.
