研究概览
简要总结
The purpose of the study is to compare parameters obtained per SL-ECG with the values from 12lead-ECG measurement. Patients who undergo out- or inpatient treatment and who receive a 12lead-ECG are asked to participate in this examination. Furthermore, 50 patients without heart disease should be included (control group).
详细描述
Atrial fibrillation is the most common cardiac arrhythmia in Germany. Clinical studies have shown that atrial fibrillation is associated with increased morbidity and mortality and reduced quality of life. Patients with atrial fibrillation have a three times higher risk of heart failure and a four to five times higher risk of ischemic stroke. In addition to these risks, atrial fibrillation is often asymptomatic and therefore more difficult to diagnose. It is estimated that about one third of all atrial fibrillation patients are asymptomatic.
For this reason, the study "Opportunistic Screening in Pharmacies for Atrial Fibrillation in Seniors" was conducted in Aachen. Within four weeks more than 7000 volunteers could be measured in participating pharmacies using a ECG hand-held diagnostic tool. Since the already measured subjects only have the SL-ECG measurement of the hand-held diagnostic tool, the aim of this substudy is to establish a reference group. In this reference group a 12lead-ECG is performed by routine ECG and a SL-ECG measurement by ECG hand-held diagnostic tool. The aim of the study is to compare the measured parameters and to optimize the algorithm to evaluate the remaining SL-ECGs of the main study.

结局指标
主要结局
Comparison of the SL-ECG (hand-held diagnostic tool) with the 12lead-ECG (gold standard) to identify and evaluate cardiac arrhythmias.
时间窗: 12 Month
The 12lead-ECG and the measurement of the hand-held diagnostic tool, performed by the proband/volunteer after the main examination, are crucial for the examination. The ECG hand-held diagnostic tool measures the heartbeat by analyzing the RR-intervals and gives a direct indication of irregularities through a red light after the measurement. Preliminary analyses showed a very good signal quality of the SL-ECG, therefore the times \[s\] and amplitudes \[mV\] of the P-wave, QRS-complex, T-wave, as well as the conduction and excitation shall be compared with each other and evaluated.
次要结局
- Analysis of SL-ECGs and validation of prognostic factors based person-specific data and their medical history.(12 Month)
