Abstract 12171: A Double-Blind Randomized Controlled Trial Comparing the Effectiveness of External Loop Monitor and Automatic Real Time Continuous Tele-ecg Cardiac Monitor in Detecting Atrial Fibrillation Among Patients With Tia: A Pilot Study
Background: Atrial fibrillation (AF), including paroxysmal AF, is known to be a major risk factor in the development of TIA and ischemic stroke.1-5 Early detection of AF is therefore key to timely management and prevention of long term complications.
Purpose: The primary purpose of this study was to compare the diagnostic yield of AF among TIA patients between Transtelephonic external loop and automatic real time continuous Tele-ECG cardiac Monitor.
Design: A single blind randomized clinical pilot trial was conducted on a convenience sample of 160 patients with confirmed TIA who have no documented AF and require cardiac monitoring.
Results: Adjusted Cox-regressions showed results that the group using the automatic real time continuous Tele-ECG cardiac Monitor.was 8 times more likely to be diagnosed with AF (HR = 8.44; 95% CI = 2.51 - 28.36) compared to those who used the external loop monitors. Interestingly, Alcohol consumption was an independent predictor of AF in our study whereby those who had one or more alcoholic drinks per day were two times more likely to have AF than those who either never or occasionally drank alcohol (HR = 2.20; 95% CI = 1.02 - 4.76).
Discussion: Our findings suggest that the use of Transtelephonic external loop monitors may not be as effective in the diagnosis of AF among TIA patients as the Automatic real time continuous Tele-ECG cardiac Monitor.
