Abstract 169: A Retrospective Study Comparing the Diagnostic Yield of Atrial Fibrillation in Patients with Transient Ischemic Attack Using External Loop Monitors and Those Using Wireless TeleECG Bluetooth Recorders
Background: AF is responsible for approximately 10 % of all ischemic strokes and is a life threatening arrhythmia that is also associated with increased mortality. Thus, early detection of AF is essential for stroke prevention
Pupose: The purpose of this study was to compare the diagnostic yield of AF between TIA patients who received cardiac monitoring with external loop monitor and patients who received cardiac monitoring with Wireless TeleECG Bluetooth Recording devices
Methods: A retrospective chart review was conducted on 1012 eligible TIA patients from January 2006 to December 2010. Data were collected on demographic and prognostic characteristics of the sample, diagnosis of AF, and the type of device used. Adjusted stepwise logistic regression analysis was performed to compare the diagnosis of AF between the two devices while accounting for covariates.
Results: Patients who were monitored with Wireless TeleECG Bluetooth Recording were over 9.0 times more likely to be diagnosed with AF than patients monitored with external loop monitor (OR = 9.15; 95%CI = 6.18 - 13.56). Other independent predictors of AF were age (OR = 1.052; 95%CI = 1.03 - 1.07), MBI (OR = 1.037; 95%CI = 1.01 - 1.07), and history of heart disease (OR = 1.77; 95%CI = 1.17 - 2.69). Interestingly, neither diabetes nor hypertension was significant predictors of AF in our sample.
Conclusion: Wireless TeleECG Bluetooth Recording are far more superior than external loop monitors with regard to diagnosis of AF. Thus, the use of Wireless TeleECG Bluetooth Recording devices could result in timely treatment of AF, which could subsequently reduce the risk of stroke. Further research within the context of clinical trials is however needed
