Since 2015 Heartrunner Sweden 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. (Ringh et al. NEJM 2015)

Today the system is fully operational in 10 of the Swedish regions and over 85 000 volunteer citizen responders are ready and willing to aid a fellow citizen suffering a cardiac arrest. 

Ongoing research in collaboration with Karolinska Institutet has the aim to evaluate survival benefits if volunteers are alerted to AEDs using the Heartrunner system. Since 2016, during the pilot phase in Stockholm the overall AED use in the region has increased with volunteers responding to alerts. 

In 2019, 1230 alerts were issued in the Stockholm region and volunteers were first on scene performing CPR and using an AED in the majority of the cases.

Swedish regions 

Since October 2016 volunteers in Gothenburg and whole of Västra Götalandsregionen are alerted using Heartrunner system and in 2018 more regions followed.

Today 10 of the 21 Swedish regions are connected to the Heartrunner system and through a distribution agreement with SOS Alarm negotiations are ongoing with several others and a national coverage is near.


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

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. After the first 40 days of alerting volunteer heartrunners in Copenhagen, media reported on two verified cases where lives were saved and mtore were to come!

In a recent publication in the Journal of the American College of Cardiology scientists reported a threefold increase of bystander defibrillation when volunteer heartrunners was fist on scene.

By may 1st 2020 TrygFonden Hjerteløber is active in all five Danish regions and this made Denmark the first European country to install a nationwide system for alerting volunteer responders for cardiac arrest. Today over 100 000 volunteers has registered as heartrunners and we will continue to update on the results of a national coverage of citizen responders in Denmark.


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

The stand-alone cloud based MissionServer that handles the geography of suspected cardiac arrests and processes the logic for candidate selection can be integrated to virtually any dispatch/PSAP software.

Our native app supports multiple languages and can be customized to the preferred look and feel of a customer to integrate well with current or coming projects in your country or region. 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 a proven track record to identify and alert volunteers for lifesaving attempts, and guide them to nearby AEDs or directly to the victim, before the ambulance arrives.

With our HeartStat module you can analyze and download data for your region and easily visualize and analyze the benefits of a system of citizen responders. HeartStat can be integrated to EMS services or PSAP for follow up as well as to hospital charts and for scientific projects.

Enable the power of volunteers in your region and benefit from your own citizen responders!
