Key result
A young patient without structural heart disease was diagnosed with rare REM-associated advanced 2nd degree atrioventricular block using polysomnography and active orthostasis testing.
Why the study?
REM-associated advanced atrioventricular block 2nd degree is a rare orphan arrhythmia, where correct diagnosis is important for guiding management strategy.
Case Report (n=1)
Demonstrates the utility of polysomnography and active orthostasis testing in diagnosing rare REM-associated advanced AV block in young patients without structural heart disease.
May aid diagnosis of rare REM-AV block; case report leaves open prevalence and management questions in young patients.
The article presents an observation of a rare clinical arrhythmia — REM-associated advanced atrioventricular block 2nd degree. The absence of structural abnormalities of the heart, the young age and the need for additional methods of instrumental examination for diagnosis (polysomnography, test with the active orthostasis test) are important features of the case. Despite the orphan nature of this arrhythmia, the correct diagnosis is important for the choice of the management strategy choice.

Pakhomova et al. (2021) conducted a case report in REM-associated advanced atrioventricular block 2nd degree (n=1). Polysomnography and active orthostasis test was evaluated. A young patient without structural heart disease was diagnosed with rare REM-associated advanced 2nd degree atrioventricular block using polysomnography and active orthostasis testing.
