Three steps. No training needed.

Switch on.
HeartHero has clear instructions for getting started – power on and a calm voice begins guiding you through every step – clearly, slowly, and in plain English.

Pull & position the pads.
Diagrams on the defib as well as each pad show exactly where to place them. The device analyses heart rhythm and decides whether a shock is needed- you don’t.

Press if prompted.
HeartHero will only authorise a shock if the rhythm requires it. You simply press the illuminated button when told. CPR guidance follows.

Public AEDs save lives – but they’re rarely close enough.
CPR helps, but it cannot restart a heart. HeartHero brings the right tool to the place it’s most needed.

After my husband’s cardiac scare last year, we couldn’t sleep without one in the house. The setup took ten minutes and the peace of mind has been priceless.

Dad had a stent fitted last spring. Mum was terrified of being alone with him. HeartHero changed that overnight — and the support team was lovely to deal with.

I expected something complicated and clinical. It’s neither. The voice prompts are calm and clear — I genuinely feel I could use it under pressure, which is the whole point.

Common concerns, answered.
Sudden cardiac arrest is triggered by an electrical malfunction in the heart that causes an irregular heartbeat (arrhythmia). It occurs suddenly and typically without warning. The heart’s pumping action is interrupted and it can’t effectively pump blood to the body’s organs. Shortly after, a person loses consciousness and will have no pulse. If an individual who has suffered cardiac arrest doesn’t receive treatment, death may occur within minutes.
Sudden cardiac arrest is not the same as a heart attack. A heart attack refers to a blockage of blood flow to the heart, whereas sudden cardiac arrest is when the heart stops beating suddenly due to an electrical malfunction.
No, people of all ages can have a sudden cardiac arrest. The most common cause is ventricular fibrillation, an irregular heart rhythm.
No, anyone can be affected by sudden cardiac arrest. Worldwide, sudden cardiac arrest is responsible for the deaths of more than 7 million people a year as cited by medscape.
Defibrillators can be found in public places, but the vast majority (80%) of sudden cardiac arrests happen at home. Every second matters when it comes to a life-saving intervention, and HeartHero allows critical care to be delivered before an ambulance arrives.
An automated external defibrillator (AED) such as HeartHero is used when someone is unresponsive and not breathing normally, or not breathing at all. An AED only shocks the heart if needed, so it is better to apply the pads when in doubt.
Using an AED to deliver an electrical shock is the sole way to treat sudden cardia arrest. Cardiopulmonary resuscitation (CPR) can keep oxygen being supplied to the brain, but is incapable of restoring the heart’s rhythm.
HeartHero is designed to be easy to use. It provides visual and audio prompts to guide users through the process. After the green power button is pushed, the red tab is pulled to turn on the device and release the pads. When the sticky pads are applied to the chest, HeartHero reads the person’s heart rhythm to determine if a shock is needed, before warning the user to stand back and delivering the shock. HeartHero will not shock a person if their heart does not need shocking, making it safe to use if in doubt whether a person is in sudden cardiac arrest.
Yes. HeartHero records detailed event data during a rescue, providing a comprehensive record of the AED’s operation and the patient’s heart rhythm throughout the event.
Following a rescue, authorised users can securely access the event data via the HeartHero app. Depending on the rescue, the report may include:
Continuous ECG/event recording.
Heart rhythm analysis performed by the AED.
Whether a shock was advised.
The number of shocks delivered, including shock energy and timing.
CPR prompts and key treatment events.
Treatment date, time and GPS location.
Device identification and treatment summary.
This information can be used for post-event review, incident documentation and operational debriefing. It provides healthcare professionals and organisations with a detailed record of the AED’s actions during the rescue.
Please note: The recorded data is intended for case review and professional consideration. It should not be used as the sole basis for diagnosis, treatment decisions or patient care.
Through the Heart Hero App. The signal is sent immediately via Bluetooth if the device is connected or downloaded at the next connection.
All four batteries need to be fully functioning for the device to work.
The device uses 4x CR123A Batteries, and comes with batteries and a set of pads at first purchase.
Yes. It is portable and can be used at both work and at home. The pads are one time use and more information is here on how to replace them.
No. HeartHero is a reusable AED. After a rescue, the pad cartridge must be replaced before the AED can be returned to service. Replacing the batteries is also recommended to ensure the AED is fully prepared for its next use.
The pre-connected cartridge contains the electrode pads, which are designed for single-patient use and must be replaced after every rescue with a new cartridge.
After using the AED, you should:
Replace the used pad cartridge with a new pre-connected cartridge.
Replace the batteries (recommended).
Download the event data if required.
Allow the AED to complete its automatic self-test before returning it to service.
The advantage of the pre-connected cartridge is that the replacement pads are already fitted in the correct orientation and ready to use, helping to reduce delays and minimise the risk of errors during the next emergency. HeartHero is designed to be used again and again. Simply replace the pad cartridge and, as recommended, the batteries, and the AED will be ready for its next emergency.
The HeartHero defibrillator has a pediatric button and single dual pads for adult and pediatric use – more information is available HERE.
No special chargers or expensive batteries are needed. HeartHero uses four standard CR123A batteries, making replacements fast and accessible from many shops and supermarkets in the UK and overseas.
The shipping charge to a UK address is £12.99 +VAT.
You should make a daily visual check to ensure the light is flashing green. A monthly full check is recommended to keep in mind the expiry of the pads.
If the Heart Hero AED is connected to the app, it will inform you if the self-check finds a fault.
The AED currently has two languages – English and Spanish. Other language options will be available via the app in the future.
No, HeartHero is lightweight and ultra-portable, fitting easily in your bag or vehicle glovebox. It is a life-saving device that you can take anywhere.
Yes; not only is HeartHero water resistant – being able to withstand exposure to moisture such as a spillage or leaking water bottle in your bag – but it is also dustproof and can operate in extreme temperatures.
HeartHero uses one set of pads for both adult and child use. Not only does this avoid any potential mix-ups during usage, but it also helps to keep the device affordable and accessible.
Put simply: It checks the heart’s rhythm and delivers a controlled electric shock to reset the heart.
A defibrillator is very easy to use and doesn’t require any training. Usually, as with Heart Hero AED, there is a single button to turn it on or pull the red lever for the pads, and simple, clear instructions will start and are spoken to you to provide guidance.
No. It only delivers an electric shock if medically necessary.
