Accuracy of Rhythm Classification Using a Data Log System in Implantable Cardioverter Defibrillators
Why the study?
Does the use of a data log system improve the accuracy of rhythm classification in patients with implantable cardioverter defibrillators compared to symptoms alone?
Population
20 patients with 32 separate tachyarrhythmia episodes
Comparison
Rhythm classification using data log information… vs Rhythm classification based on symptoms alone
Design
Cross-sectional

Implication
Data logs may improve ICD tachyarrhythmia classification over symptoms alone; hypothesis-generating pending prospective validation.
Structured PICO
Does the use of a data log system improve the accuracy of rhythm classification in patients with implantable cardioverter defibrillators compared to symptoms alone?
P
Population
20 patients with 32 separate tachyarrhythmia episodes
I
Intervention
Rhythm classification using data log information (Telectronics ATP 4210) alone or combined with symptoms
C
Comparator
Rhythm classification based on symptoms alone
O
Outcome
Sensitivity, specificity, and predictive accuracy of rhythm classificationsurrogate
Data log information from ICDs significantly improves the accuracy of tachyarrhythmia rhythm classification compared to relying on patient symptoms alone.
