Positive results of study on atrial fibrillation with an automatic
screening algorithm ASA (SRA) published in Cardiovascular Disease Magazin
Apoplex medical technologies, Pirmasens, Geratherm Medical, Geschwenda,
24.08.2010. In a study for detection of paroxysmal atrial fibrillation in
acute stroke patients, clinicians from university hospital at Heidelberg
compared in 136 patients SRA (technology from apoplex medical
technologies) with the conventional 24 hour long term ECG. While the 24
hour ECG examination revealed 23 % of the patients later found as having
paroxysmal atrial fibrillation during monitor surveillance, the SRA test
identified 72% with just a one hour examination in the emergency room.
The study has been published at the 18 th of August 2010 , by the
department of Neurology in cooperation with the departments of Cardiology
and Epidemiology and Aging Reaseach at the German Cancer Reseach Center
(DKFZ) at the University of Heidelberg.
Abstract:
Background: Atrial fibrillation (AF) is a frequent cause of stroke, but
detecting paroxysmal AF (pAF) poses a challenge. We investigated whether
continuous bedside ECG monitoring in a stroke unit detects pAF more
sensitively than 24-hour Holter ECG, and tested whether examining RR
interval dynamics on short-term ECG recordings using an automated screening
algorithm (ASA) for pAF detection is a useful tool to predict the risk of
pAF outside periods of manifest AF.
Methods: Patients >60 years with acute ischemic stroke or transient
ischemic attacks (TIA) were prospectively enrolled unless initial ECG
revealed AF or they had a history of paroxysmal or persistent AF. ASA was
performed on 1- to 2-hour ECG recordings in the emergency room and patients
were classified into 5 risk categories for pAF. All patients underwent
continuous bedside ECG monitoring for >48 h. Additionally, 24-hour Holter
ECG was performed. Results: 136 patients were enrolled (median age: 72
years, male: 58.8%). In 29 (21.3%), pAF was newly diagnosed by continuous
bedside ECG monitoring. pAF increased with age (p = 0.031). Median time to
first pAF detection on continuous bedside ECG monitoring was 36 h. In 16
patients, pAF was detected by continuous bedside ECG monitoring prior to
the performance of 24-hour Holter ECG. Thirteen of the remaining patients
were pAF positive on continuous bedside ECG monitoring, but 24-hour Holter
detected only 3 patients. Accordingly, the sensitivity of 24-hour Holter
was 0.23. Sensitivity of higher-risk categories of ASA compared to
continuous bedside ECG monitoring was 0.72, and specificity 0.63.
Conclusion: Continuous bedside ECG monitoring is more sensitive than
24-hour Holter ECG for pAF detection in acute stroke/TIA patients.
Screening patients for pAF outside AF episodes using ASA requires further
development.
