If you are experiencing dizziness or a sensation of wooziness in your head upon standing upright, or if you have episodes of sudden falls, you may be suffering from intermittent heart blockage. This condition is called heart block.

Heart block can occur when the electrical signals that control your heartbeat are partially or completely blocked. In some cases, this may be due to a complete loss of heart activity, known as asystolic arrest, or a complete heart block.

In either case, you may require support with a permanent pacemaker to maintain a regular heartbeat and prevent further episodes.

Pacemaker Therapy ?

A pacemaker is a small medical device used to help manage abnormal heart rhythms, ensuring the heart beats at a normal rate. Dr. Masood Ahmed, a renowned interventional cardiologist, offers state-of-the-art pacemaker therapy at Saleem Memorial Hospital in Lahore. With over 33 years of experience in treating cardiovascular conditions, Dr. Masood specializes in delivering personalized, advanced care to patients experiencing slow or irregular heart rhythms that interfere with their daily lives.

What is a Pacemaker?

A pacemaker is a small device placed under the skin near the heart. It uses electrical pulses to regulate the heart’s rhythm and help maintain a consistent heartbeat. It is primarily used to treat bradycardia, a condition where the heart beats too slowly, and other arrhythmias (irregular heartbeats) that can affect the heart’s ability to pump blood effectively.

For patients with bradycardia, the heart’s natural pacemaker (the sinoatrial node) doesn’t function properly, causing the heart rate to drop below normal levels. This can lead to symptoms such as dizziness, fatigue, shortness of breath, and fainting. In these cases, a pacemaker is a lifesaving solution.

Why Might You Need a Pacemaker?

Several conditions may lead to the need for pacemaker therapy, including:

Bradycardia (Slow Heart Rate): When the heart rate falls below normal, the body’s organs and tissues may not receive enough oxygen-rich blood, leading to dizziness, weakness, and fainting.

Sick Sinus Syndrome (SSS): This is a condition where the heart’s natural pacemaker (the sinoatrial node) malfunctions, leading to abnormal heart rhythms such as intermittent slow heart rate (bradycardia), rapid heart rate (tachycardia), or even both.

Heart Block: A condition where the electrical signals in the heart are delayed or blocked, preventing the heart from beating in a regular pattern. It can cause a slow heart rate, dizziness, and fatigue.

Atrial Fibrillation (AF): In some cases, patients with AF may require a pacemaker, especially if they also have a slow heart rate or require a rhythm management strategy after other treatments fail.

Fainting or Dizziness (Syncope): Unexplained fainting episodes or dizziness can sometimes be linked to a slow or irregular heart rhythm. In these cases, a pacemaker can help restore normal rhythm and prevent further symptoms.

Congenital Heart Disorders: Some individuals are born with heart conditions that can cause abnormal rhythms, requiring pacemaker implantation.

Types of Pacemakers

There are several types of pacemakers, each tailored to a specific patient’s needs. The two most common types include:

Single-Chamber Pacemaker
Dual-Chamber Pacemaker
Biventricular Pacemaker (CRT):

How Does Pacemaker Therapy Work?

A pacemaker is a small medical device that helps regulate your heartbeat by sending gentle electrical impulses to the heart. It ensures that the heart maintains a steady and appropriate rhythm.

The device has two main components:

Pulse Generator – A small, battery-powered unit implanted just under the skin near the collarbone. It contains the circuitry that produces electrical impulses.

Leads (Wires) – Thin, flexible wires that connect the generator to the heart. They carry the impulses directly to the heart muscle to stimulate proper contractions.

The pacemaker constantly monitors the heart’s natural rhythm. If it detects that the heart is beating too slowly, it automatically delivers electrical impulses to correct it. Modern pacemakers can also adjust the pacing rate depending on the patient’s activity level—helping the heart keep up with daily demands.

How much does a pacemaker cost in Pakistan

The cost of a pacemaker in Pakistan can range from PKR 580,000
to PKR 600,000 depending on the type of pacemaker, the hospital, and the expertise of the doctor.

. What kind of doctor monitors pacemakers?

Pacemakers are typically monitored by an interventional cardiologist or a cardiac electrophysiologist who specializes in heart rhythm disorders.

Can you live 20 years with a pacemaker?

Yes, many patients with a pacemaker can live for 20 years or more, as pacemakers are designed to last a long time, with regular monitoring and battery replacement when needed.

Which brand of pacemaker is best?

Top pacemaker brands include Medtronic, Abbott, Boston Scientific, and Biotronik, known for their reliability, advanced features, and long battery life. Your cardiologist will help choose the best option based on your condition.
