HeartStart FRx

For those who get there first

With a Rugged and reliable construction the HeartStart FRx AED makes it perfect for the first responder

Rugged design - Ready for real-world use

The HeartStart FRx was built to surpass rigorous testing requirements: withstanding jetting water, crushing loads of up to 500 pounds, and a one-meter drop onto concrete.

On-demand CPR coaching

Talks you through your training

The HeartStart FRx features CPR coaching and intuitive icon-driven operation. Calm, clear voice instructions are tailored to the responder’s actions, providing guidance during the resuscitation of an SCA victim.


At just 3.5 pounds, the HeartStart FRx is light and portable, allowing for easy transport. Its size and weight make it perfect for police officers, firefighters, and trained public servants.

Built-in self test

Ready when needed

Your HeartStart FRx goes through a 120-point test before it leaves the factory. On the job, it conducts self tests every single day, not just weekly. It performs over 80 different tests in all. Even the pads are tested for readiness.

SMART Biphasic therapy

Safely delivers maximum shock strength

Philips SMART Biphasic therapy uses a unique combination of high current - to increase effectiveness, and a lower energy dose - to decrease side effects that are harmful to a fragile heart.

Quick Shock

Minimize chest compression interruptions

CPR is even more vital to survival than previously realized. Rapidly delivering a shock after chest compressions is critical. The HeartStart FRx’s Quick Shock feature reduces the time between hands-off and shock delivery.


Model Number 861304

How the Defibrillator is supplied: Battery (one, pre-installed), SMART Pads II (one set, pre-installed), Set up / Maintenance guide with expiration date tags, Owner's Manual, Quick Reference Guide.

Waveform Truncated Exponential Biphasic. Waveform parameters adjusted as a function of each patient’s impedance.

Therapy Adult defibrillation peak current: 32A (150J nominal) into a 50 ohm load. Pediatric defibrillation (with optional Infant/Child Key installed): 19A (50J nominal) into a 50 ohm load.

Protocol Protocol Device follows preconfigured settings. Defibrillation and CPR protocol can be customized using HeartStart Event Review or HeartStart Configure software.

Patient Analysis

Patient Analysis Evaluates patient ECG to determine if a rhythm is shockable. Rhythms considered shockable are ventricular fibrillation (VF), and certain ventricular tachy-cardias (VT) associated with lack of circulation. For safety reasons, some VT rhythms associated with circulation will not be interpreted as shockable, and some very low-amplitude or low-frequency rhythms will not be interpreted as shockable VF.

Sensitivity / Specificity Meets AAMI DF80 guidelines and AHA recommendations for adult defibrillation (Circulation 1997;95:1677-1682).

Shock Advised Able to deliver a shock as soon as the device indicates a shock is advised.

Quick Shock Able to deliver a shock after the end of a CPR interval, typically in eight seconds.

Shock-to-Shock Cycle Time Typically less than 20 seconds between shocks in a series.

Artifact Detection Advanced signal processing allows accurate ECG analysis even in the presence of most pacemaker artifact and electrical noise sources. Other artifacts are detected and corrective voice prompts issued.
