Exploring the prevalence of undetected bradyarrhythmia in dementia with Lewy bodies
(2023) In Clinical autonomic research : official journal of the Clinical Autonomic Research Society 33(4). p.433-442- Abstract
PURPOSE: To explore the prevalence of undetected bradyarrhythmia in a cohort of people with dementia with Lewy bodies.
METHODS: Thirty participants diagnosed with dementia with Lewy bodies were enrolled from three memory clinics in southern Sweden between May 2021 and November 2022. None had a history of high-grade atrioventricular block or sick sinus syndrome. Each participant underwent orthostatic testing, cardiac [
123I]metaiodobenzylguanidine scintigraphy and 24-h ambulatory electrocardiographic monitoring. Concluding bradyarrhythmia diagnosis was obtained until the end of December 2022.
RESULTS: Thirteen participants (46.4%) had bradycardia at rest during orthostatic testing and four had an average heart rate... (More)

RESULTS: Thirteen participants (46.4%) had bradycardia at rest during orthostatic testing and four had an average heart rate < 60 beats per minute during ambulatory electrocardiographic monitoring. Three participants (10.7%) received a diagnosis of sick sinus syndrome, of whom two received pacemaker implants to manage associated symptoms. None received a diagnosis of second- or third-degree atrioventricular block.
CONCLUSION: This report showed a high prevalence of sick sinus syndrome in a clinical cohort of people with dementia with Lewy bodies. Further research on the causes and consequences of sick sinus syndrome in dementia with Lewy bodies is thus warranted.
