Atrial Fibrillation Screening With a Smartphone Device and iECG Application

Study Overview
=================
Brief Summary
-----------------
Question: Can atrial fibrillation (AF) cases in patients ≥ 65 years be easily detected in a primary healthcare environment using a smartphone device and iECG application as an opportunistic screening tool? Objectives: Detection of AF through cardiac rhythm abnormalities in patients ≥65 years old in an opportunistic screening program using a smartphone device/application Define the predictable value of the smartphone device with electrocardiogram (ECG) confirmation to detect AF in patients 65 years and older Correlate screened patients cardiovascular risk profile and those that register cardiac rhythm irregularities for a better description of the general characteristics of Colombian population

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of patients screened in whom the screening device detect an abnormal cardiac rhythm |  | Up to 6 months | 
| Number of patients screened in whom Atrial Fibrillation (AF) was confirmed with ECG |  | Up to 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of patients in whom abnormal cardiac rhythm was detected with screening device and AF was confirmed with ECG | Predictive value tests - Positive: Number of patients screened in whom AF was confirmed with ECG/ Number of patients screened in whom the screening device detect an abnormal rhythm - Negative: Number of patients screened in whom AF was discarded with ECG/ Number of patients screened in whom the screening device detect an abnormal rhythm | Up to 6 months |
