The Cardiac Science Powerheart G3 AED, not to be confused with the older Cardiac Science Powerheart, existed in 4 different versions:
- Model 9300E: Cardiac Science Powerheart G3 semi-automatic
- Model 9300A: Cardiac Science Powerheart G3 fully automatic
- Model 9390E: Cardiac Science Powerheart G3 Plus semi-automatic
- Model 9390A: Cardiac Science Powerheart G3 Plus fully automatic
The first 2 models 9300E and 9300A have been available on the market for a long time, these were later supplemented with the “Plus” models 9390E and 9390A. These “Plus” versions contain more extensive texts and a metronome of 100 beats per minute, for the correct chest compression frequency compared to the “normal” Powerheart G3.
After the appearance of the two Plus models, the two normal models slowly faded into the background and in the Netherlands almost exclusively Plus versions of the Cardiac Science were sold in 2012, unlike some other European countries, such as England, where the standard version remained popular for a long time.
In July 2014, Cardiac Science announced that they would stop selling the Powerheart G3 AEDs in Europe. Partly because of the introduction of the new Powerheart G5 but also because of new EU regulations (RoHS Directive – Restriction of Hazardous Substances). These regulations indicated that the housing of the Powerheart G3 contained substances that were prohibited within the EU.
Outside of Europe, the sale of the Cardiac Science Powerheart G3 has continued, evidenced by the many web stores that offer this AED outside of Europe. The Powerheart G3 is also still topical in press releases from Cardiac Science themselves. Accessories for the Powerheart G3 are also still available.
Recently (April / May 2019) we have heard rumours through several channels, that the Cardiac Science Powerheart G3 AED would be put back into production for the European market, but we do not yet have any official reports confirming this.
There is also a fifth model of the Powerheart G3, the Cardiac Science Powerheart G3 Pro. This Cardiac Science Powerheart G3 Pro (model number 9300P) is an AED that is sold very little in the Netherlands. The G3 Pro is based on the Powerheart G3, but with a few extras such as a colour screen, the possibility of ECG monitoring and the possibility of manual operation (manual over-ride).
