Internal Cardioverter Defibrillator: Who Needs It and Precautions To Keep In Mind
Introduction
What Is an Internal Cardioverter Defibrillator?
Who Needs an Internal Cardioverter Defibrillator in UAE?
An internal cardiac defibrillator in UAE is advised for patients who are at higher risk of having serious ventricular arrhythmias. This includes patients who:
- Have a history of sudden cardiac arrest or ventricular fibrillation.
- Are suffering from coronary heart disease or coronary artery disease, which has weakened the heart muscles.
- Are suffering from congenital heart disorders, which increase the risk of rapid dangerous heart rhythms.
- Have severe heart failure with abnormal electrical conduction.
- Are diagnosed with rare conditions that may affect the heartbeat.
Precautions After Implantable Cardioverter Defibrillator Procedure
After an Implantable Cardioverter Defibrillator procedure, following the right precautions is necessary for the smooth functioning of the internal cardiac defibrillator and long-term heart health. While most patients can return to normal life within a few weeks, the following precautions must be taken to avoid complications.
Care for the implant site
Keeping the incision area clean and dry until it heals completely is a must. Any signs of infection, such as redness, swelling, warmth, or discharge, should be reported to the doctor immediately.
Limiting arm movement initially
For the first 4 to 6 weeks, lifting heavy objects or raising the arm on the side of the implant above shoulder level should be avoided. This helps prevent the leads from shifting while they settle into position.
Following activity guidelines
Light activities like walking are encouraged, but strenuous exercise, contact sports, and heavy lifting should be avoided until the cardiologist approves. Physical activity should be gradually resumed based on medical advice.
Always carrying an ICD identification card
Always keeping an ICD ID card helps healthcare providers and security personnel understand the individual’s condition, especially during emergencies or airport screenings. The identification card carries important information like the type of ICD, and in an emergency, this card will give the doctor critical data that could save the patient’s life.
No high-intensity activity
People having an ICD should not indulge in rough contact sports or activities without the approval of the cardiologist. The pressure put on the body can cause damage to the device.
Keep caution from magnetic devices
Most household electronics are safe, but keeping mobile phones at least 6 inches away from the ICD site is advised. People with an ICD that is not MRI compatible should exercise caution with magnetic devices such as MRI scanners.
Follow driving restrictions
If an implantable cardioverter defibrillator is implanted to treat ventricular arrhythmias, the patient should avoid driving for a certain period depending on the country. Abnormal heart rhythms, along with the electrical therapy delivered by the ICD, can sometimes cause dizziness or fainting, which increases the risk of accidents while driving a vehicle.
Attending regular follow-ups
Routine check-ups are critical to monitor battery life, lead function, and device settings in dedicated pacemaker clinic. Many modern ICDs allow remote monitoring, but in-clinic evaluations remain important.
Consult a doctor in case of shock
If the patient receives a shock and then feels fine, inform the doctor. In case of multiple shocks, feeling dizzy, fainting, or experiencing chest pain, seeking emergency medical attention immediately is a must.
Taking medications as prescribed
Patients must continue all heart medications exactly as directed. The ICD supports the heart rhythm but does not replace the need for medical therapy.
Conclusion
The internal cardioverter defibrillator has transformed the way life-threatening heart rhythm disorders are managed, offering patients a powerful defense against sudden cardiac death. With its ability to monitor, detect, and treat dangerous arrhythmias instantly, this device is one of the most important developments in cardiovascular medicine.
