Since 2015 Heartrunner Sweden AB has provided the technical platform for the SMS Livräddare project in Stockholm. In the beginning it was a research project, led by the Center for Resuscitation Science at Karolinska Institutet, with the aim to evaluate if bystander CPR rates increased when volunteers were alerted. The results showed an 30 % increase in bystander CPR rates in cases where volunteers were alerted through their cellphones.

Today the system is fully operational and there are over 15 000 volunteers ready and willing to aid a fellow citizen suffering a cardiac arrest. 

Future research is planned in collaboration with Karolinska Institutet with the aim to evaluate survival benefits if volunteers are alerted to AEDs using the Heartrunner system. Since 2016, during the pilot phase, more than 1 500 alerts on suspected cardiac arrest has been issued in Stockholm and the overall AED use has increased. 


Since October 2016 volunteers in Gothenburg and whole of Västra Götalandsregionen are alerted using Heartrunner system.   After the first months in the region over 5 000 volunteers are active and ready to aid a fellow citizen suffering a cardiac arrest.

Västra Götalandsregionen is scheduled to participate in the AED/survival study conducted by Karolinska Institutet but the prehospital administration has also performed a quality control project during the past year.

It´s to early at this stage to conclude our effect but since the introduction of the Heartrunner system in Västra Götalandsregionen the use of AEDs in has increased dramatically.


In corporation with TrygFonden in Denmark the Heartrunner system is implemented in the capital region of Denmark under the name, TrygFonden Hjerteløber, and the app is released during EMS2017.

By implementing the Heartrunner system and using the TrygFonden Hjerteløber app to alert motivated volunteers to provide early CPR and use an AED the aim is to increase the use of AEDs and survival in cardiac arrest. A scientific evaluation will be performed and with sudden cardiac arrest being a national concern TrygFonden has the intention to implement the Hjerteløber app in all regions in Denmark over the coming years.

After the first 40 days of alerting volunteer lifesavers in Copenhagen media reported on two verified cases where lives were saved and soon there will be more!


Heartrunner is developed to be adapted to your regions needs in your effort to save lives.

The standalone cloud based MissionServer that handles the geography of suspected cardiac arrests and processes the volunteer locations can be integrated to virtually any dispatch software.

Our native app supports multiple languages and can be customised to the preferred look and feel of a customer to integrate well with current or coming projects. The app reads web content from any source and can support regional projects or campaigns as well as support volunteers with CPR reminders.

Do your region or country have an AED registry? Great! The Heartrunner system can manage and display data from AED registries and the with the system currently in use in Sweden and Denmark, it has proven to identify and alert volunteers for lifesaving attempts, and guide them to nearby AEDs or directly to the victim, before the ambulance arrives.
