Key result
Early use of implantable cardiac monitors provides a higher diagnostic yield for elucidating the etiology of unexplained syncope compared to conventional non-invasive testing.
Why the study?
What are the strategies and evidence-based recommendations for using ambulatory cardiac monitoring modalities to diagnose the cause of syncope?
What are the strategies and evidence-based recommendations for using ambulatory cardiac monitoring modalities to diagnose the cause of syncope?
This review provides strategies for utilizing various ambulatory cardiac monitoring devices to diagnose syncope based on current evidence-based recommendations.
May guide ICM selection in unexplained syncope; leaves open RCTs on outcomes and cost.
Elucidating the cause of syncope is often a diagnostic challenge. At present, there is a myriad of ambulatory cardiac monitoring modalities available for recording cardiac rhythm during spontaneous symptoms. We provide a comprehensive review of these devices and discuss strategies on how to reach the elusive diagnosis based on current evidencebased recommendations.

Subbiah et al. (2014) conducted a review in Syncope. Ambulatory cardiac monitoring (Holter, external event recorders, implantable cardiac monitors) vs. Conventional testing was evaluated. Early use of implantable cardiac monitors provides a higher diagnostic yield for elucidating the etiology of unexplained syncope compared to conventional non-invasive testing.
