Pacemaker & Leadless Pacemaker Implantation in Hyderabad | Heart Rhythm Specialist | Dr. Praneeth Polamuri
What Is a Pacemaker?
A pacemaker is a small medical device implanted to help regulate the heart's rhythm when it beats too slowly or irregularly.
Think of the heart's electrical system as the wiring in a house. If the electrical signals become delayed or blocked, the lights may flicker or stop working properly.
Similarly, when electrical signals in the heart are disrupted, the heart may beat too slowly, causing symptoms such as dizziness, fatigue, or fainting.
A pacemaker monitors the heart's rhythm and delivers electrical impulses when needed to maintain an appropriate heart rate.
Why Might Someone Need a Pacemaker?
Pacemakers are commonly used to treat:
-
Slow Heart Rate (Bradycardia) - The heart beats too slowly to supply enough blood to the body.
-
Heart Block - Electrical signals between the upper and lower chambers are delayed or blocked.
-
Sick Sinus Syndrome - The heart's natural pacemaker does not function properly.
-
Certain Types of Heart Failure - Specialized pacemakers (CRT devices) help improve coordination of heart contractions.
Common Symptoms of Slow Heart Rhythm
-
Dizziness
-
Fatigue
-
Fainting
-
Near-fainting episodes
-
Shortness of breath
-
Reduced exercise capacity
-
Palpitations
-
Difficulty performing daily activities
How Is a Pacemaker Implanted?
Step 1: Local Anesthesia - The procedure is usually performed under local anesthesia with mild sedation.
Step 2: Vein Access - A small incision is made below the collarbone.
Step 3: Lead Placement - Thin insulated wires (leads) are guided through veins into the heart.
Step 4: Device Implantation - The pacemaker generator is connected to the leads and placed under the skin.
Step 5: Testing - The system is tested before the procedure is completed.
What Is a Leadless Pacemaker?
A leadless pacemaker is a newer generation pacemaker that is implanted directly inside the heart without traditional wires (leads) or a chest incision.
Think of it as replacing a traditional wired device with a compact wireless system.The entire pacemaker is delivered through a catheter inserted into a vein in the groin.
Advantages of Leadless Pacemakers
Compared with traditional pacemakers:
-
No chest incision
-
No visible device under the skin
-
No leads
-
Lower risk of lead-related complications
-
Faster recovery
-
Excellent cosmetic outcome
Who Is a Candidate for a Leadless Pacemaker?
Leadless pacemakers may be suitable for selected patients with:
-
Symptomatic bradycardia
-
Atrial fibrillation with slow heart rates
-
Previous device infection
-
Limited venous access
-
High risk of lead complications
What Is Cardiac Resynchronization Therapy (CRT)?
Some heart failure patients develop uncoordinated contraction of the heart muscle.CRT uses a specialized pacemaker to synchronize heart contractions and improve pumping efficiency.
CRT may:
-
Improve symptoms
-
Improve exercise capacity
-
Reduce hospitalization
-
Improve quality of life
What is an ICD?
An Implantable Cardioverter Defibrillator (ICD) is different from a standard pacemaker.
An ICD:
-
Monitors heart rhythm continuously
-
Detects dangerous arrhythmias
-
Delivers life-saving therapy when needed
It may be recommended for patients at risk of sudden cardiac death.
Recovery After Pacemaker Implantation
Most patients:
-
Go home within 24–48 hours
-
Resume light activities within a few days
-
Return to normal routines within 1–2 weeks.
Your cardiologist will provide specific instructions regarding arm movement and activity.
Living With a Pacemaker
Most patients can:
-
Walk
-
Exercise
-
Travel
-
Work
-
Use mobile phones
-
Pass through airport security with minimal restrictions.
Regular follow-up ensures the device continues functioning optimally.
A Reassuring Thought
Needing a pacemaker does not mean your life must slow down. Modern pacemakers are highly reliable and help many patients return to active, independent lives with improved energy and confidence.
Frequently Asked Questions (FAQ)
1. What is a pacemaker?
A pacemaker is a small device implanted to help regulate slow or abnormal heart rhythms.
2. Why would someone need a pacemaker?
Pacemakers are commonly used to treat slow heart rates, heart block, and certain rhythm disorders.
3. What are the symptoms of a slow heart rate?
Common symptoms include dizziness, fatigue, fainting, breathlessness, and reduced exercise capacity.
4. Is pacemaker implantation a major surgery?
No. It is usually a minimally invasive procedure performed under local anesthesia.
5. How long does pacemaker implantation take?
Most procedures take between 45 minutes and 2 hours.
6. Will I be awake during the procedure?
Yes. Most patients remain awake with mild sedation.
7. Is pacemaker implantation painful?
Most patients experience minimal discomfort during and after the procedure.
8. How long will I stay in the hospital?
Many patients are discharged within 24–48 hours.
9. What is a leadless pacemaker?
A leadless pacemaker is a miniature pacemaker implanted directly inside the heart without leads or a chest incision.
10. What are the advantages of a leadless pacemaker?
Leadless pacemakers eliminate leads, reduce lead-related complications, and avoid a visible chest device.
11. Is a leadless pacemaker better than a traditional pacemaker?
Each has advantages. The best choice depends on the patient's condition and pacing requirements.
12. How long does a pacemaker battery last?
Most pacemaker batteries last between 8 and 15 years depending on usage.
13. What happens when the battery runs low?
The generator can be replaced through a relatively simple procedure.
14. Can I exercise with a pacemaker?
Yes. Most patients can return to regular physical activity after recovery.
15. Can I use a mobile phone with a pacemaker?
Yes. Modern pacemakers are designed to function safely around mobile phones.
16. Can I undergo MRI with a pacemaker?
Many modern devices are MRI-compatible. Always inform healthcare providers about your device.
17. Will airport security scanners affect my pacemaker?
Modern pacemakers are generally safe around airport security systems.
18. What is CRT?
Cardiac Resynchronization Therapy is a specialized pacemaker used to improve heart function in selected heart failure patients.
19. What is an ICD?
An Implantable Cardioverter Defibrillator is a device that detects and treats dangerous heart rhythms.
