Think of a pacemaker as a tiny electrical backup for your heart. It’s implanted just under the skin and steps in whenever your natural rhythm slows down or misfires. Doctors implant well over a million of these devices worldwide every year, and bradycardia, a heart rate that’s too slow, is the most common reason. It’s not only an “old age” thing either. Younger patients with heart block or certain heart failure conditions need one too. The type you actually end up with comes down to your diagnosis, your age, and how active your day to day life is.
According to Dr. Krishna Dhoot, an interventional cardiologist in Pune, “A cardiac pacemaker isn’t a cure; it’s a correction. Once the heart rhythm is stabilised, patients can usually return to their normal lives.”

Which Type of Pacemaker Is Right for You?
There isn’t one universal pacemaker. The right device depends on which part of your heart’s electrical system is malfunctioning and the specific rhythm problem being treated.
| Pacemaker Type | Chambers Paced | Best Suited For |
| Single Chamber | One, usually the right ventricle | Occasional, isolated slow rhythm |
| Dual Chamber | Right atrium and right ventricle | Heart block or timing issues between chambers |
| Biventricular (CRT) | Both lower chambers | Heart failure with a rhythm delay |
| Leadless | Sits directly inside the heart, no wires | Select cases, lower infection risk |
Recovery time and follow-up visits differ depending on the type of pacemaker,so this isn’t a decision made on symptoms alone. It needs a proper ECG and echo workup first. A cardiologist with experience implanting different types of pacemakers can determine which device is most appropriate for your specific condition.

How Do You Know If You Need a Pacemaker?
- Persistent fatigue: Feeling tired even after a full night’s rest may be associated with an abnormal heart rhythm or reduced cardiac output.
- Fainting or dizziness: Unexplained fainting can occur when the brain temporarily receives insufficient blood flow due to an abnormal heart rhythm.
- Reduced exercise tolerance: Difficulty climbing stairs or performing activities that were previously manageable may warrant medical evaluation.
- Irregular or rapid pulse: If your pulse frequently feels like it is skipping, racing, or beating unusually slowly, consult a healthcare professional and consider an ECG.
Why Choose Dr. Krishna Dhoot for Pacemaker Implantation?
Dr. Krishna Dhoot is an interventional cardiologist with 18+ years of experience in clinical and interventional cardiology. He holds two international fellowships: Fellow of the European Society of Cardiology (FESC) and Fellow of the Society for Cardiovascular Angiography & Interventions (FSCAI).
He has performed 30,000+ angiographies and 10,000+ angioplasties, reflecting extensive experience in interventional cardiac procedures.
His approach focuses on understanding the patient’s diagnosis and choosing treatment based on the individual’s cardiac condition, rather than taking a one-size-fits-all approach

Frequently Asked Questions
Does pacemaker surgery hurt?
Not much. It’s done under local anaesthesia, you’ll stay awake and comfortable.
How long does the battery last?
Usually 8 to 15 years, depending on the device and how hard it’s working
Can I still use my phone afterward?
Yes, just avoid resting it directly on top of the device.
Is this a major surgery?
No, it’s minimally invasive and most people are done inside an hour.
