CardioSight Clinic in Rohini, Delhi provides comprehensive pacemaker services, from initial evaluation and cardiac workup through permanent pacemaker implantation and long-term device follow-up. If you or a family member has been diagnosed with a slow heart rate or heart block, a specialist assessment can help determine whether a pacemaker is the right treatment.
Dr. Abhinav Aggarwal is an experienced Interventional Cardiologist offering pacemaker implantation in Rohini, Delhi. Patients benefit from a complete evaluation at the clinic, expert device selection and a structured follow-up programme to ensure optimal pacemaker performance over the long term.
Who Needs a Pacemaker?
A pacemaker is a small electronic device implanted under the skin to regulate the heart's electrical activity. It sends electrical impulses to the heart when the natural heart rate is too slow or when the electrical conduction system is not functioning properly. Common conditions that may require a permanent pacemaker include:
- Bradycardia (slow heart rate) — the heart beats too slowly to meet the body's needs, causing dizziness, fatigue or fainting.
- Heart block — a delay or complete block in the electrical signals that coordinate heartbeats, including second-degree and complete (third-degree) heart block.
- Sick sinus syndrome — the heart's natural pacemaker (the sinus node) does not generate impulses reliably, resulting in alternating slow and fast heart rhythms.
- Heart failure requiring CRT — selected patients with heart failure and a wide QRS complex may benefit from Cardiac Resynchronisation Therapy (CRT), a specialised pacemaker that coordinates the pumping of both ventricles.
Symptoms such as recurrent dizziness, unexplained fainting (syncope), persistent fatigue, breathlessness at rest, and a documented slow pulse should prompt evaluation by a cardiologist experienced in cardiac rhythm disorders and device implantation.

The Pacemaker Implantation Procedure
Pacemaker implantation is a relatively straightforward procedure performed under local anaesthesia with sedation. It does not require open-heart surgery. The key steps include:
- The area below the collarbone is numbed with local anaesthetic.
- A small incision is made, and one or more thin, flexible leads (wires) are introduced through the subclavian vein and guided to the heart chambers under fluoroscopic (X-ray) guidance.
- The leads are positioned in the right atrium, right ventricle, or both, depending on the type of pacemaker required.
- The leads are tested to confirm satisfactory sensing and pacing thresholds.
- A small pocket is created under the skin below the collarbone, and the pulse generator (the battery unit) is connected to the leads and placed in the pocket.
- The incision is closed, and a dressing is applied.
The procedure typically takes one to two hours. Patients remain awake throughout and may feel some pressure, but significant pain is not expected.
Types of Pacemakers
Single-Chamber Pacemaker
Has one lead placed in either the right atrium or the right ventricle. Used in selected patients with specific types of heart block or sinus node dysfunction.
Dual-Chamber Pacemaker
Has two leads — one in the right atrium and one in the right ventricle. This allows the pacemaker to coordinate the timing between the upper and lower chambers of the heart, maintaining a more natural heart rhythm. This is the most commonly implanted type.
CRT / Biventricular Pacemaker
Has three leads — one each in the right atrium, right ventricle and left ventricle (via the coronary sinus). This device is used in selected patients with heart failure and a wide QRS complex to improve the coordination and pumping efficiency of the heart (Cardiac Resynchronisation Therapy).
Recovery and Device Follow-Up
Hospital Stay
- Patients are typically monitored overnight after implantation.
- A chest X-ray and device check are performed before discharge.
- Most patients are discharged the next day.
Wound Care & Precautions
- Keep the wound clean and dry for the initial healing period.
- Avoid raising the arm on the implant side above shoulder level for 4–6 weeks.
- Avoid heavy lifting and vigorous upper-body activity during the initial weeks.
- Report any redness, swelling or discharge at the wound site.
Device Check Schedule
- First follow-up typically at 1–2 weeks post-implant.
- Routine device interrogation every 6–12 months.
- Battery status, lead impedance and sensing thresholds are checked at each visit.
- Remote monitoring may be available for compatible devices.
Frequently Asked Questions
How long does a pacemaker battery last?
Modern pacemaker batteries typically last 8 to 15 years, depending on the type of device, how frequently it paces the heart, and the programmed settings. Battery status is checked at each routine device follow-up, and a generator replacement is planned well before the battery is fully depleted.
Can I live a normal life with a pacemaker?
Yes. Most patients with pacemakers return to their normal daily activities, including light exercise, driving and travel. Your cardiologist will advise you on any specific precautions based on your individual condition. Carrying a pacemaker identification card is recommended.
Are there devices or situations I should avoid with a pacemaker?
Most household electrical devices are safe. However, patients should avoid prolonged close contact with strong magnets and certain industrial equipment. MRI scans may be possible with MRI-conditional pacemakers under specific protocols. Always inform medical professionals about your pacemaker before any procedure, including dental work and surgery.
What is the cost of pacemaker implantation in Delhi?
The cost of pacemaker implantation in Delhi depends on the type of device (single-chamber, dual-chamber or CRT), the manufacturer, hospital charges and whether the patient has health insurance coverage. During your consultation, Dr. Abhinav Aggarwal can discuss the most appropriate device for your condition and provide a clear estimate of the expected costs.
Book a Pacemaker Consultation
If you or a family member has been diagnosed with a slow heart rate, heart block or has been advised pacemaker implantation, a specialist cardiology consultation can help you understand your condition, review your reports and discuss the most appropriate treatment options.
