Study 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.

Study arms

  • Active comparator
    Group A : defibrillator ECG to patchy-type ECG

    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

  • Experimental
    Group B : patchy-type ECG to defibrillator ECG

    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

Interventions

  • Devicepatchy-type wireless ECG

    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.

  • Devicedefibrillator ECG

    This device is essential equipment in ambulance. For 12-lead ECG examination the connector need to replace for specific cable.
