What Is a Pacemaker? A Simple Guide for Patients
Have you ever felt dizzy for no clear reason, or felt unusually tired even after resting? Sometimes these feelings are caused by a heartbeat that is too slow or too irregular. In such cases, a doctor may recommend a small device called a pacemaker.
Dr. Nikhila Pachani, Consultant Interventional Cardiologist at Backbone Medicity Hospital, Rajkot, recently shared a helpful video explaining what a pacemaker is — and why it matters for patients across Gujarat.
What Does the Heart's Electrical System Do?
Your heart beats because of tiny electrical signals that travel through it in a steady rhythm. When these signals are disrupted, the heart can beat too slowly, too fast, or in an uneven pattern. This is called an arrhythmia.
Some common conditions that cause these problems include:
- Sick Sinus Syndrome — the heart's natural pacemaker (the sinus node) does not work properly, causing a slow or irregular heartbeat.
- Tachy-Brady Syndrome — the heart switches between beating too fast and too slow.
- These conditions can lead to syncope (sudden fainting), dizziness, breathlessness, and extreme tiredness.
What Is a Pacemaker?
A pacemaker is a small, battery-powered device. It is placed just under the skin, usually near the collarbone. It connects to the heart through thin wires called leads.
The device continuously monitors your heart's rhythm. Whenever it senses the heart is beating too slowly or skipping beats, it sends a gentle electrical signal to prompt the heart to beat normally again.
Who May Need a Pacemaker?
A cardiologist may suggest pacemaker implantation if you:
- Frequently feel dizzy or faint (syncope)
- Feel extreme fatigue without a clear cause
- Have been diagnosed with Sick Sinus Syndrome or Tachy-Brady Syndrome
- Have a consistently slow heart rate confirmed on an ECG or Holter monitor
Is the Procedure Safe?
Pacemaker implantation is a well-established cardiac procedure. Most patients recover steadily and are able to return to their normal daily activities after a recovery period advised by their doctor.
Pacemaker implantation may also be covered under Ayushman Bharat – PM-JAY (ABPMJAY), a government health scheme, making it more accessible for eligible patients in Gujarat and across India.
When Should You See a Doctor?
If you or a family member in Rajkot or nearby areas of Gujarat experiences repeated episodes of dizziness, fainting, or unexplained fatigue, it is worth speaking to a qualified cardiologist. Early evaluation can make a meaningful difference.
