Why an ICD + Pacemaker Is Not an Outpatient Procedure

. 

Understanding the seriousness of advanced heart failure and why this surgery matters

When someone you love is facing heart failure, the world splits into two groups: the people living it, and the people who think they understand it.

From the outside, an implantable cardioverter defibrillator (ICD) and pacemaker can sound like simple devices something doctors “just pop in” during a quick outpatient procedure. But that perception is dangerously incomplete. The truth is that an ICD‑pacemaker combination is recommended only when a person’s heart is in serious trouble, and the surgery is not a casual event. It is a life‑preserving intervention for a life‑threatening condition.

This article explains, in clear terms, what these devices do, why they’re needed, and why this surgery deserves the gravity and respect it commands. 

Pacemaker vs. ICD: What’s the Difference?

Most people have heard of pacemakers. They’re familiar, almost comforting  a device that helps regulate a slow heartbeat.

But an ICD is something entirely different.

Pacemaker

• Treats bradycardia, a heart rate that is too slow
• Sends gentle, low‑energy pulses to keep the heart beating regularly
• Helps with rhythm support, not emergency rescue

ICD (Implantable Cardioverter Defibrillator)

• Designed for life‑threatening fast heart rhythms
• Can stop ventricular tachycardia or ventricular fibrillation, the rhythms that cause sudden cardiac arrest
• Can deliver powerful, life‑saving shocks when the heart becomes chaotic
• Often includes pacemaker functions, but is used for far more serious conditions, including advanced heart failure

In simple terms:
A pacemaker helps a slow heart.
An ICD saves a dying heart. 

Why Doctors Recommend an ICD + Pacemaker Combo

This combination is not suggested lightly. It is used when:

• The heart’s electrical system is failing
• The pumping strength (ejection fraction) is dangerously low
• The patient is at high risk for sudden cardiac arrest
• Medications have failed or caused harm
• The heart can no longer maintain a safe rhythm on its own

This is not a “routine upgrade.”
This is a life‑preserving intervention for someone whose heart is struggling to keep them alive.  

Why This Surgery Is Necessary in This Case

In this situation, the need for an ICD and pacemaker is not just about long‑term rhythm support  it is about a sudden and dangerous decline in heart function.

My husband had untreated myocarditis from a COVID infection he contracted in January 2020. Despite repeatedly going to the doctor and reporting ongoing symptoms, the underlying myocarditis was not recognized or treated. It was only after he suffered a heart attack that the severity of his condition became clear.

Because the myocarditis went undiagnosed, he was treated as though he had typical congestive heart failure. In reality, he had electrical heart failure caused by the earlier viral injury to his heart. The medications used for congestive heart failure were not appropriate for his condition, and the wrong medication caused significant harm.

My husband experienced a severe adverse reaction to the heart‑failure medication, and his ejection fraction fell to 15%. At that level, the heart is barely able to pump enough blood to sustain the body, and the risk of sudden cardiac arrest becomes extremely high. This decline was not due to progression of his original condition, but to the reaction he had to the medication that was not suited for electrical heart failure.

Because of this medication‑induced decline:

• The heart can no longer maintain a safe rhythm
• The electrical system is unstable
• The risk of life‑threatening arrhythmias is high
• A pacemaker alone is not enough
• An ICD is required to prevent sudden cardiac arrest
• Both devices must work together to support the heart

This is not a routine pacemaker situation.
This is a serious cardiac emergency requiring advanced intervention. 

This Is Not an Outpatient Procedure  Not for Someone With Serious Heart Failure

People hear “pacemaker” and assume a same‑day procedure.
But that is not the reality here.

Because the heart is so fragile, this surgery is not outpatient. It requires a 2-3 day hospital stay for:

• Continuous heart monitoring
• Careful medication adjustments
• Observation for arrhythmias
• Management of fluid balance
• Ensuring the device is functioning safely
• Stabilizing the heart after the procedure

A typical pacemaker patient goes home the same day.
A typical ICD patient may stay overnight.

A 2-3 day hospitalization signals a much more serious medical situation  one that requires close, round‑the‑clock care.  

The Emotional Reality

When friends or family brush this off as “no big deal,” it can feel like they’re minimizing the reality you’re living:

• The fear
• The uncertainty
• The seriousness of the diagnosis
• The fact that this device is being implanted because the heart is failing

People often minimize what they don’t understand. This article exists so they can finally understand.

The Bottom Line

An ICD‑pacemaker combination is not a convenience.
It is not a routine gadget.
It is not “just outpatient.”

It is a life‑saving device used only when a person’s heart is in real danger.

And when the surgery requires a 2-3 day hospital stay, it is because the medical team knows the heart needs careful, continuous support during and after the procedure.  This deserves respect, compassion, and seriousness not dismissal.

Note the 2-3 day hospital stay was based on my husband’s heart failure.  Consult your doctor to find out if hospital stay will be needed.  Many do go home the same day.
