Atrial Fibrillation
Conditions
Brief summary
Randomised crossover study comparing the sensitivity and specificity of 5 External loop recorders in detecting pacemaker detected Atrial fibrillation burden.
Detailed description
The purpose of the study is to compare the diagnostic accuracy of the ZIO xt , MoMe, TECHNOMED pocket ECG and Nuubo to the R-test, our current standard clinical practice, in detection of AF burden, in patients with history of Paroxysmal Atrial Fibrillation and have a dual chamber pacemaker or ICD in situ, with sensitivity and specificity of AF detection calculated from the implanted pacemaker monitored beat to beat holters.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity and specificity in detection of pacemaker detected AF burden in comparison to R-test | 14 weeks | Sensitivity and specificity of ZIO xt patch, MoMe, TECHNOMED pocket ECG AND Nuubo in detection of pacemaker detected AF burden in comparison to R-test. Sensitivity and sepcificity will be determined by the percentage of pacemaker detected AF episodes that have been detected by each ELR device. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| proportion of pacemaker detected tachyarrhythmias detected in comparison to R-test | 14 weeks | Proportion of pacemaker detected tachyarrhythmias detected by the ZIO xt patch, MoMe, TECHNOMED pocket ECG and Nuubo in comparison to R-test |
| Total wear time in comparison to R-test | 14 weeks | Total wear time of the ZIO xt patch, MoMe, TECHNOMED pocket ECG and Nuubo in comparison to R-test |
| Proportion of symptomatic arrhythmias detected in comparison to R-test | 14 weeks | Proportion of symptoms secondary to arrhythmias detected by the ZIO xt patch, MoMe, TECHNOMED pocket ECG and Nuubo compared to R-Test |
| Cost effectiveness in detection of arrhythmias in comparison to R-test | 14 weeks | Cost-effectiveness of ZIO xt patch, MoMe, TECHNOMED pocket ECG and Nuubo in detection of arrhythmia in comparison to R-Test |
Other
| Measure | Time frame | Description |
|---|---|---|
| User satisfaction in interpretation of reports compare | 14 weeks | Ease of interpretation of results summary derived by device software - validated by questionnaire provided to junior & senior Cardiologists and junior & senior Physiologists |
| Participant feedback on device tolerability assessed by Visual Analogue Score (VAS) questionnaire | 14 weeks | Participant feedback on device tolerability assessed by Visual Analogue Score (VAS) questionnaire |
