Key result
EP testing remains unestablished for sinus bradycardia but helps locate AV block for permanent pacing.
Why the study?
Does electrophysiological testing improve diagnosis and management in patients presenting with bradycardia due to sinus node or atrioventricular node disease?
Does electrophysiological testing improve diagnosis and management in patients presenting with bradycardia due to sinus node or atrioventricular node disease?
Electrophysiological testing is useful for evaluating AV conduction disturbances to guide permanent pacing, but its role in sinus bradycardia remains unestablished.
Answers are grounded in this paper and cite their sources.
Supports selective use in AV conduction disturbances for pacing decisions; leaves open its role in sinus bradycardia.
In this article we review the role of electrophysiological testing in patients presenting with bradycardia due to sinus node or atrioventricular node disease. In sinus bradycardia the role of electrophysiology studies is not established. In AV conduction disturbances, an electrophysiology study may be necessary both for the establishment of atrioventricular block as the main cause of symptoms, and for identification of the anatomic site of block that may dictate the potential need of permanent pacing.

Katritsis et al. (2017) conducted a review in Bradycardia due to sinus node or atrioventricular node disease. Electrophysiological testing was evaluated. Electrophysiological testing has an unestablished role in sinus bradycardia but may be necessary in AV conduction disturbances to identify the anatomic site of block for permanent pacing.
