Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Interventional
Description of intervention(s) / exposure
Treatment: Devices - 360J LifePak Monitor/Defibrillator
Treatment: Devices - 200J Philips HeartStart MRx Monitor/Defibrillator

Active comparator: 360J LifePak Monitor/Defibrillator - The standardised cardioversion protocol below performed with a 360J shock from a Lifepak Monitor/Defibrillator.

1. First shock with anteroposterior pad configuration
2. In event of failure of the above, a second shock with anterolateral pad configuration
3. In event of failure of the above, a third shock with anteroposterior pad configuration + manual pad pressure

Active comparator: 200J Philips HeartStart MRx Monitor/Defibrillator - The standardised cardioversion protocol below performed with a 200J shock from a Philips HeartStart MRx Monitor/Defibrillator.

1. First shock with anteroposterior pad configuration
2. In event of failure of the above, a second shock with anterolateral pad configuration
3. In event of failure of the above, a third shock with anteroposterior pad configuration + manual pad pressure
4. The addition of a fourth 'rescue' shock at 360J using the LifePak Monitor/Defibrillator with pads in the anteroposterior configuration in the event of the first three steps failing to cardiovert to sinus rhythm


Treatment: Devices: 360J LifePak Monitor/Defibrillator
The LifePak Monitor/Defibrillator is a commonly-used defibrillator in New Zealand hospitals for cardioverting atrial fibrillation. It delivers a biphasic waveform shock with a titratable maximum energy of 360J.
