Timely Acquirement of 12-lead ECG Using Patchy-type Wireless Device by Emergency Medical Technician in Ambulance

Study Overview
=================
Brief Summary
-----------------
In this study, the investigators compare timely acquirement and effectiveness of 12-lead ECG using patchy-type wireless versus using defibrillator which contain ECG examination function in ambulance. The purpose of this study is to determine the difference of timely acquirement of 12-lead ECG using two different systems and the difference of efficiency of ECG examination in ambulance between two groups. The participants in this simulation study were divided randomly into 2 groups : Group A is performing an ECG examination on mock patient using defibrillator which contained 12-lead ECG checking function. And take a 15 minutes wash out period. After the wash out period, group A subject performing an ECG examination using patchy-type wireless device. Group B subject is performing an ECG examination on mock patient using patchy-type wireless device first, and take a 15 minutes wash out period. After the wash out period, group B performing an ECG examination using defibrillator which contain 12-lead ECG function. Both group's ECG examination is performing in the ambulance.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Group A : defibrillator ECG to patchy-type ECG<br>Group A subject will performing ECG examination to a mock patient in the ambulance. First ECG performance will be using defibrillator which contain 12-lead ECG checking function. And taking a 15 minutes wash out period. Second ECG performance after wash out period, will be using patchy-type wireless device. when ECG examination performance ended, survey of patchy-type wireless ECG device usability will be collect. | Device: defibrillator ECG<br>* This device is essential equipment in ambulance. For 12-lead ECG examination the connector need to replace for specific cable.<br>|
| Experimental: Group B : patchy-type ECG to defibrillator ECG<br>Group B subject will performing ECG examination to a mock patient in the ambulance. First ECG performance will be using patchy-type wireless device. And taking a 15 minutes wash out period. Second ECG performance after wash out period, will be using defibrillator which contain 12-lead ECG checking function. when ECG examination performance ended, survey of patchy-type wireless ECG device usability will be collect. | Device: patchy-type wireless ECG<br>* This device consists of a single patchy and save the ECG result as a Potable Document Format. Also can transfer to hospital using wifi-network.<br>|
