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 at any given time, 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. Over 12 000 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.

The use of AEDs has increased dramatically

This quality control showed an increase of bystander CPR and a dramatic increase of AED use and the region aim to validate increased survival.


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.

In november 2018 data from 12 month of operation in Copenhagen was presented at the American Heart Association conference in Chicago, USA. This data showed one or more volunteer heartrunner on scene before ambulance in 40 % of the cases and a threefold increase of bystander defibrillation.

Your region

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

The standalone cloud based MissionServer handles the suspected cardiac arrests and process the volunteer locations. Virtually any dispatch software can easily integrate through an API and this requires minimal work on PSAP side.

Does your region or country have an AED registry? Great!

The Heartrunner app support 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 customer created source and can thus support regional projects or campaigns and support volunteers with CPR reminders.

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.

Please reach out and let’s discuss how we can help you increase bystander CPR and AED use in your region. Let´s join forces and increase the chance of survival in cardiac arrest!
