An implantable cardioverter defibrillator (ICD) is a compact, battery-powered device that is surgically implanted into the chest. Its primary function is to detect and correct irregular heart rhythms, known as arrhythmias. The ICD continually monitors the heart’s rhythm and administers electrical shocks when necessary to restore a normal heartbeat.
Individuals may require an ICD if they experience life-threatening rapid heart rhythms like ventricular tachycardia or ventricular fibrillation. Additionally, an ICD might be recommended for those with a heightened risk of dangerous arrhythmias, typically due to a weakened heart muscle.
It’s important to note that an ICD differs from a pacemaker, which is designed to prevent excessively slow heartbeats.
Cardiac therapy devices include devices like ICDs. Two basic types include the following: (1 all)
An implantable cardioverter-defibrillator (ICD) is a medical device designed to continuously monitor and promptly correct irregular heart rhythms. It is particularly beneficial in cases of sudden and complete loss of heart activity, a condition known as cardiac arrest.
ICDs serve as the primary treatment option for individuals who have survived cardiac arrest. Furthermore, they are increasingly being employed in individuals at a high risk of experiencing sudden cardiac arrest. An ICD significantly reduces the risk of sudden death from cardiac arrest compared to relying solely on medication.
If you exhibit symptoms of a sustained irregular heart rhythm called sustained ventricular tachycardia, such as fainting, your cardiologist may recommend the implantation of an ICD. Additionally, an ICD might be advised if you have:
Potential complications associated with implantable cardiac defibrillators (ICDs) or the surgical procedure for implantation can include:
Prior to receiving an implantable cardiac defibrillator (ICD), a series of heart health assessments are typically conducted. These assessments may include:
Before the ICD procedure, patients are generally instructed not to eat or drink for several hours.
It is important to inform your healthcare team about all medications you are taking and inquire whether it is advisable to take them before the ICD procedure.
Getting an implantable cardioverter defibrillator (ICD) involves a few important steps:
Usually, only one shock is required to restore a regular heartbeat. Some individuals may experience two or more shocks within a 24-hour period.
After your ICD procedure, you’ll typically head home the following day. During the recovery period, you might experience swelling and tenderness around the ICD placement site for a few days or weeks. Your doctor may prescribe pain medication for relief, but remember to avoid aspirin and ibuprofen, as they can increase the risk of bleeding.
For approximately eight weeks post-ICD implantation, it’s important to refrain from sudden movements that raise your left arm above your shoulder. This precaution helps prevent the device wires from shifting while the area heals. Depending on the type of ICD you received, you may need to limit your driving. Your healthcare team will provide specific guidance on when it’s safe to resume driving and other daily activities.
During the first four weeks following the ICD implant, your healthcare team may advise against the following activities:
Additionally, your doctor may recommend avoiding contact sports altogether after getting an ICD. A blow to the chest area could potentially damage the ICD or displace its wires.
ICDs (Implantable Cardioverter Defibrillators) are generally safe, but there are some precautions to consider:
Devices with low or no risk include microwave ovens, TVs, remote controls, radios, toasters, electric blankets, shavers, drills, computers, scanners, printers, and GPS devices.
Patients who receive an ICD must schedule routine check-ups to have the device and their heart checked.
An ICD’s lithium battery has a five-to seven-year lifespan. Typically, routine medical check-ups, which should take place roughly every six months, involve a battery check. Find out how frequently they should get checked out by asking the healthcare provider. A brief outpatient surgery is performed to replace the generator when the battery is almost dead.
Any shocks the patient receives from their ICD should be reported to the healthcare provider. The shocks may give anyone an anxious feeling. However, what they really mean is that the ICD prevents sudden death and treats a cardiac rhythm issue.
Inform the patient’s healthcare provider if they have any infection-related symptoms following ICD implantation surgery:
It is important to seek immediate medical attention if the patient experienced severe shocks for only a short period of time after ICD surgery.
