Restoring Your Heart’s Rhythm, Protecting Your Future

At Emerald Coast Heart & AFib, we specialize in cutting-edge heart rhythm management, including pacemakers and implantable cardioverter defibrillators (ICDs). These life-changing devices restore and protect your heart’s rhythm, allowing you to live confidently and actively.

If you or a loved one is considering a pacemaker or ICD, this guide will walk you through everything you need to know—including how they work, who needs them, how they’re implanted, and what life looks like after getting one.


Pacemakers: Keeping Your Heart on Track

What is a Pacemaker & How Does it Work?

A pacemaker is a small, battery-powered device that regulates the heartbeat by delivering electrical pulses to keep your heart beating at a normal rate and rhythm.

Why is this important? If your heart beats too slowly (bradycardia) or irregularly, it can cause fatigue, dizziness, fainting, or even heart failure. A pacemaker ensures your heart keeps a steady, healthy rhythm so you can stay active and feel your best.

Fun Fact: Pacemakers are smaller than a matchbox and last 8-15 years before needing a battery replacement!

Types of Pacemakers

Pacemakers come in different types, depending on which part of the heart needs support:

  • Single-Chamber Pacemaker Sends electrical signals to one chamber of the heart (either the right atrium or right ventricle).
  • Dual-Chamber Pacemaker Sends signals to two chambers—both the right atrium and right ventricle—allowing for a more synchronized heartbeat.
  • Cardiac Resynchronization Therapy (CRT-P) Used in heart failure patients, it synchronizes the contractions of both ventricles, improving the heart’s pumping ability.
  • Leadless Pacemaker The latest innovation—tiny, wireless, and placed directly inside the heart! It’s ideal for select patients and removes the need for traditional leads.

At Emerald Coast Heart & AFib, we match you with the best pacemaker for your specific needs using the latest advancements in cardiac technology!

Who Needs a Pacemaker?

A pacemaker is recommended for patients with:

  • Bradycardia (slow heart rate) – Your heart beats too slowly, causing fatigue, dizziness, or fainting.
  • Heart Block – Electrical signals from the upper chambers (atria) don’t reach the lower chambers (ventricles) properly.
  • Atrial Fibrillation with Slow Ventricular Response – AFib that slows your heart too much, causing symptoms.
  • Heart Failure (CRT-P candidates) – If your heart is weak and needs help pumping blood efficiently.

A quick heart rhythm evaluation will determine if you’re a pacemaker candidate!

How is a Pacemaker Implanted?

A pacemaker implantation is a quick, outpatient procedure that typically takes less than an hour. Here’s what to expect:

  • Conscious Sedation – You’ll be relaxed but awake (not general anesthesia).
  • Small Incision – A 2-inch incision is made just below your collarbone.
  • Lead Placement – Thin wires (leads) are inserted into a vein and guided to your heart using X-ray imaging.
  • Device Placement – The pacemaker is positioned under the skin, and the leads are connected.
  • Testing & Closure – The device is tested, programmed specific to your heart, sutures are absorbable, under the skin

Recovery Time? Most patients go home the same day and resume normal activities within a few days!

Implantable Cardioverter Defibrillators (ICDs): Preventing Dangerous Heart Rhythms

What is an ICD & How Does it Work?

An Implantable Cardioverter Defibrillator (ICD) is a small device that monitors your heart and automatically delivers a life-saving shock if a dangerous heart rhythm (ventricular tachycardia or fibrillation) occurs. Dr. Weisberg often describes them as “a pacemaker that has the ability to shock your heart if you suddenly have a life-threatening arrhythmia.”

Think of an ICD as a “guardian angel” for your heart—it constantly watches for life-threatening arrhythmias and responds within seconds to prevent sudden cardiac arrest.

Types of ICDs

Traditional ICD Placed under the skin, with leads (wires) that go into the heart.
Subcutaneous ICD (S-ICD) Leadless—the wires stay outside the heart, reducing risks associated with traditional leads.

Who Needs an ICD?

ICDs are recommended for people with:

History of Sudden Cardiac Arrest or Ventricular Tachycardia
Severely Reduced Heart Function (EF ≤ 35%)
Genetic Arrhythmia Syndromes (e.g., Long QT, Brugada Syndrome)

Your cardiac electrophysiologist will determine if an ICD is right for you!

Leading ICD Manufacturers:

The same top four companies also manufacture ICDs:
Abbott (formerly St. Jude Medical)
Boston Scientific
Medtronic
Biotronik

How is a ICD Implanted?

A ICD implantation is a quick, outpatient procedure that typically takes less than an hour. Here’s what to expect:

  • Conscious Sedation – You’ll be relaxed but awake (not general anesthesia).
  • Small Incision – A 3-inch incision is made just below your collarbone.
  • Lead Placement – Thin wires (leads) are inserted into a vein and guided to your heart using X-ray imaging.
  • Device Placement – The ICD is positioned under the skin, and the leads are connected.
  • Testing & Closure – The device is tested, programmed specific to your heart, sutures are absorbable, under the skin

Recovery Time? Most patients go home the same day and resume normal activities within a few days!

FAQs About Pacemakers & ICDs

What is it like living with a pacemaker or ICD?
Most people forget they even have one! Your device is constantly working in the background to keep your heart safe.

Are there any restrictions?
✅ No restrictions on using microwaves, smartphones, or laptops!
🚫 Avoid powerful magnets (like large industrial equipment or generators). Some pacemakers and ICDs are now MRI compatible.
🚫 No skydiving or SCUBA diving (above 8,000 feet or below 40 feet deep). Some exceptions are made.

Can I exercise with a pacemaker or ICD?
Absolutely! Low-impact activities are encouraged and can even be done at high intensities, but always check with your doctor.

Will I feel shocks from my ICD?
ICDs only activate for dangerous rhythms. A shock does hurt but it is usually saving your life!

How often does my device need to be checked?
✅ Regular remote monitoring
✅ In-office checks every 6-12 months

Implantable Loop Recorders: Uncovering Hidden Heart Rhythms

For patients with unexplained fainting, dizziness, palpitations, irregular heartbeats or suspected AFib, an Implantable Loop Recorder (ILR) can provide continuous heart monitoring for months to years, helping us diagnose hidden arrhythmias that standard tests might miss.

🔍 What is an Implantable Loop Recorder?

An ILR is a tiny, wireless device that continuously records your heart rhythm, storing important data whenever an abnormal event occurs. It allows us to detect conditions like AFib, bradycardia, and unexplained arrhythmias that could otherwise go undiagnosed.

🛠️ How is an ILR Implanted?

  • Quick, simple procedure – the device is “injected” through a tiny incision
  • Local anesthesia only – no IV needed!
  • A tiny incision (the size of the charging port on your phone!) on the skin of your chest
  • Procedure takes 5-10 minutes, and patients can drive home afterward!

Fun Fact: Dr. Weisberg has had nurses get their ILR implanted on their lunch break and return to work right after! It’s that easy!

🔋 How Long Does it Last?

ILRs provide continuous heart monitoring for 3-5 years, depending on how frequently it records events. Once we have the answers we need, the device can be easily removed in the office.

Remote Monitoring: Heart Protection from Anywhere

At Emerald Coast Heart & AFib, we believe that the best care happens beyond the office visit—which is why we’ve partnered with Vector Remote Care to monitor our patients’ heart devices for alerts 365 days a year.
