Implantable Cardioverter Defibrillator (ICD) Procedure

A Look at Implantable Cardioverter Defibrillator (ICD) Procedure 

Implantable Cardioverter Defibrillators (ICDs) are designed to monitor and regulate heart rhythms for those at high risk of experiencing a heart attack or other cardiac emergency. 

If you or someone you know is navigating heart rhythm concerns, understanding ICDs can provide valuable insights into managing cardiac health. 

Here, we'll delve into what ICDs are, how they work, and the impact they can have on enhancing cardiovascular health. Continue reading to learn more.

What Is an Implantable Cardioverter Defibrillator?

An implantable cardioverter defibrillator (ICD) is a heart care device designed to treat and prevent life-threatening arrhythmias, particularly ventricular arrhythmias, which can led to sudden death. The ICD insertion is under the skin, usually in the chest area, and connected to the heart through one or more leads (thin insulated wires).

The primary function of an ICD is to monitor the heart's rhythm continuously. If it detects an abnormal and potentially life-threatening heart rhythm, the ICD can deliver an electrical shock to the heart to restore normal rhythm. This process is known as defibrillation.

In addition to defibrillation, many ICDs also have pacing capabilities. They can deliver pacing pulses to the heart to treat slower heart rhythms, such as bradycardia. This dual functionality makes ICDs versatile devices for managing various heart rhythm problems.

ICDs are typically recommended for individuals at high risk of sudden cardiac death due to a history of certain cardiac conditions, such as those with a history of heart attack. 

Types of ICD

There are several types of implantable cardioverter defibrillators. The four main types include

  1. Single-Chamber ICDs
    These devices have one lead, usually placed in the right ventricle. They are primarily used when the ventricles are the primary site of arrhythmias.
  2. Dual-Chamber ICDs
    Dual-chamber ICDs have two leads—one in the right atrium and one in the right ventricle. This allows the device to monitor and treat arrhythmias in both the atrium and ventricles.
  3. Biventricular (Cardiac Resynchronization Therapy) ICDs (CRT-D)
    These devices are designed for individuals with heart failure and electrical desynchrony. They have three leads—one in the right atrium and one in each ventricle. The synchronized pacing helps improve the coordination of the heart's contractions.
  4. MRI-Compatible ICDs 
    Some ICDs are designed to be compatible with magnetic resonance imaging (MRI), allowing patients to undergo this diagnostic procedure on their hearts when necessary.

The Benefits of a Defibrillator Implant

An ICD implant procedure can offer several benefits for those at risk of life-threatening cardiac arrhythmias. 

Here are some of the key benefits

  • Prevention of Sudden Cardiac Death (SCD)
    Monitors and shocks the heart back to a normal rhythm, preventing life-threatening conditions. 
  • Treatment of Ventricular Arrhythmias
    Treats dangerous heart rhythms.
  • Continuous Monitoring
    Provides real-time data to healthcare providers, allowing early intervention for arrhythmias.
  • Pacing Capabilities
    Delivers pacing pulses to maintain a steady heart rhythm, treating slower heart rhythms.
  • Reduced Hospitalizations
    Decreases hospital visits related to arrhythmias, contributing to better overall cardiac health management.
  • Improved Quality of Life
    Provides a sense of security, allowing individuals to engage in daily activities confidently.
  • Customization for Individual Needs
    Different ICDs are available to suit specific cardiac conditions and preferences.

What's Involved in an ICD Implant Procedure?

The ICD insertion procedure involves several key steps. 

First, the patient is prepared for the procedure with sedation or anesthesia. Then, a small incision is made on the left side of the chest to create a pocket for the ICD device.

Thin, insulated wires called leads are threaded through blood vessels into the heart, and the ICD device, containing the battery and electronic components, is placed in the pocket just under the skin. The leads are connected to the device, and the system is tested to ensure proper functioning, including pacing, sensing, and defibrillation capabilities. 

After implantable cardioverter defibrillator placement, the incision is closed with stitches or staples, and the patient is monitored briefly before going home.

Regular follow-up appointments are scheduled to monitor the device's performance and address concerns. 

Frequently Asked Questions About Implanted Cardioverter Defibrillator

Are you curious about the implanted cardioverter defibrillator? Here are answers to some common questions to help you understand these life-saving devices better.

Will an ICD Insertion Cure My Heart Rhythm Problem?

No, an implantable cardioverter defibrillator doesn't cure the underlying heart rhythm problem, but it can treat and manage life-threatening arrhythmias by restoring normal heart rhythm through timely defibrillation. 

Do ICD Shocks Hurt?

ICD shocks may cause discomfort, but they are typically brief. The sensation is often described as a sudden jolt or thump. 

If Someone Touches Me When I Get an ICD Shock, What Will Happen to Them?

If someone touches you during an ICD shock, they will not be harmed. The shock is specific to your heart and does not pose a risk to others.

After ICDs, Can I Return to Life as It Was Before?

After receiving an ICD, many people can resume their normal activities. It's essential to follow your healthcare provider's guidance and attend regular check-ups to ensure the device functions correctly and make any necessary lifestyle adjustments.

Where Will the Defibrillator Be Placed?

The defibrillator will be placed just under the skin, typically in the upper chest. The specific location may vary based on individual factors and patient anatomy.

Is the Implant Procedure an Open-Heart Surgery?

No, the implant procedure for an ICD is not open-heart surgery. It involves making a small incision on the left side of the chest to create a pocket for the device's placement.

How Is the Implantable Cardioverter Defibrillator Powered?

The ICD implant is powered by a battery located within the device. The battery provides the necessary energy for the ICD, including monitoring the heart's rhythm and delivering shocks if needed.

Can People With ICDs Go Near Microwave Ovens?

Yes, people who undergo an ICD procedure can go near microwave ovens without significant risk. Modern ICDs are designed to withstand common electromagnetic interference, including that produced by household appliances like microwaves.

I’m about one month out and things are so much better. At my two week evaluation my symptom score had gone from a 27 to a 7, and I’m sure it’s even better now. That speaks volumes. Now that I’m post recovery, there is no incontinence, I go to the bathroom much less and there are no ED side effects like there are with other procedures. In regard to my quality of life, well, I don’t maintain my life based on my proximity to a bathroom anymore.

Blaine P., M.D.
Professional staff working in a beautiful facility with great doctors who sincerely care about their patients. Without Dr. Schmidt's skill, I would have needed heart bypass surgery instead of a stent. Follow-up has been thorough. I can't recommend them highly enough.
LeAnn H.

Dr. Jim Melton and all the staff are fantastic. He is an excellent surgeon and his team is GREAT!!!! I just had surgery at the surgery center, I have only great things to say about my experience. Without him I really don't think I would be here to write this. If you’re looking for a good cardiovascular team, they are a 5 star for sure.

Dr. John Schrader is the most personable doctor we know. He stays on top of my dads health care and is genuinely concerned about his health. We never leave his office with questions. He answers them all. Even questions we don’t think of. Always professional but never cold or bad bedside manner. In our opinion he is THE BEST around.
Thank you Dr Schrader.

I came to Dr. Warren by a self referral for mals when it took me 8yrs 50+ doctors and thousands of dollars spent on no answers. My first visit I was scared I was just going to be gaslighted just like the past however I was pleasantly shocked when Dr. Warren immediately believed me. She took the time to review many disk I had brought from past tests. She never once dismissed me and listened to ever word I had to say. She scheduled one last test to confirm the diagnosis then I was scheduled for surgery right away. Surgery was a success and I can’t thank her and her staff enough. Dr. Warren truly saved my life.
