What’s involved in getting an ICD, and will it affect my daily life? 

An Implantable Cardioverter Defibrillator (ICD) is a sophisticated piece of medical technology that acts as a 24-hour emergency service for your heart. For those at risk of life-threatening ventricular arrhythmias, receiving an ICD is a major clinical step that offers unparalleled protection against sudden cardiac arrest. While the idea of having an electronic device ‘installed’ inside your body can feel daunting, the reality for most patients is a return to a safe and active life. In the UK, the process, from the initial recommendation to the procedure and recovery, is a well-established clinical pathway designed to be as minimally invasive as possible. This article explains exactly what is involved in getting an ICD and provides a realistic look at how the device will (and will not) affect your daily routines, hobbies, and peace of mind.

What is Involved in Getting an ICD? 

The process of receiving an ICD involves a minor surgical procedure, usually performed under local anaesthetic with sedation. Unlike open-heart surgery, the procedure takes place just beneath the skin near your collarbone. 

The Implantation Procedure 

1. Preparation: You will be given a sedative to make you relaxed and drowsy. The area near your shoulder will be numbed with local anaesthetic. 

2. The Incision: A small incision (about 5–7cm) is made just below the collarbone, creating a ‘pocket’ under the skin or muscle. 

3. Lead Placement: One or more thin, flexible wires (leads) are threaded through a vein and guided into the chambers of your heart using X-ray imaging for precision. 

4. Testing and Connection: The leads are connected to the ICD box (the ‘generator’). The team will test the electrical connections to ensure the device can ‘see’ your heart rhythm perfectly. 

5. Closing: The incision is closed with stitches or medical glue. The entire procedure usually takes between 1 and 2 hours. 

The Hospital Stay 

Most patients in the UK stay in the hospital for one night for observation. A chest X-ray is performed the next morning to ensure the leads haven’t moved, and the device is checked one final time before you are discharged home. According to NHS guidance, you will be given an ICD identification card that you must carry with you at all times. 

Will It Affect My Daily Life? 

For the majority of patients, an ICD does not stop them from enjoying a full life. However, because it is an electrical device sensitive to magnetic fields, there are specific ‘common-sense’ adjustments you need to make. 

1. Physical Activity and Hobbies 

• Recovery Phase: For the first 4 to 6 weeks, you must avoid lifting your arm on the side of the device above shoulder height. This allows the leads to ‘bed in’ to the heart muscle. 

• Long-term Exercise: Most sports are fine once you have recovered. You should, however, avoid contact sports (like rugby or martial arts) where the device might be physically hit or the leads damaged. 

• Travel: Flying is safe, but you must tell airport security about your ICD. You should be hand-searched or walked through the scanner quickly, as the metal in the device may trigger the alarm. 

2. Electronic Devices and Magnets 

Modern ICDs are well-shielded, but you should avoid placing strong magnets directly over the device. 

• Mobile Phones: Keep your phone at least 6 inches (15cm) away from your ICD. Do not carry it in a breast pocket on the same side as the device. 

• Household Appliances: Microwaves, blenders, and standard power tools are safe. 

• Industrial Equipment: Avoid arc welding or standing near strong industrial magnets, as these can interfere with the device’s ability to sense your rhythm. 

3. Driving and the DVLA 

This is often the biggest adjustment for UK patients. The DVLA has strict rules for anyone with an ICD, as a shock or a fainting episode while driving could be dangerous. 

• Primary Prevention (Risk only): You usually have to stop driving for 1 month. 

• Secondary Prevention (After a cardiac arrest or shock): You may have to stop driving for 6 months or longer. 

• HGV/Bus Licences: Unfortunately, having an ICD usually means you are permanently disqualified from holding a Group 2 (commercial) licence. 

Living with the ‘Guardian’ 

An ICD sits silently until it is needed. Most patients never feel the device working, as it only intervenes if it detects a dangerous, rapid rhythm. 

• Remote Monitoring: You may be given a monitor to keep by your bed. It automatically ‘reads’ your ICD while you sleep and sends the data to your hospital clinic. 

• The Battery: ICD batteries typically last between 5 and 8 years. When the battery is low, the entire generator box is replaced in a simple procedure that is even faster than the initial implantation. 

• What a Shock Feels Like: If the ICD delivers a life-saving shock, it is often described as feeling like a sudden, powerful ‘kick in the chest.’ While startling, it is over in a fraction of a second. 

Conclusion 

Getting an ICD is a significant step toward long-term safety, providing a constant internal backup against sudden cardiac events. While the procedure involves a minor operation and requires some adjustments to your driving and physical habits, the ‘trade-off’ is the ability to live with much greater confidence and security. In the UK, the support provided by arrhythmia clinics and remote monitoring ensures that your device is always performing optimally. By understanding the practical safety rules, such as keeping magnets at a distance and following DVLA guidelines, you can ensure that your ICD remains a silent, effective guardian that allows you to focus on living your life rather than worrying about your heart rhythm. 

If you experience severe, sudden, or worsening symptoms, call 999 immediately.
