A pacemaker is a small, sophisticated electronic device implanted near the heart to regulate abnormal heart rhythms. Pacemaker implantation plays a crucial role in managing conditions where the heartbeat is irregular, either too slow or too fast. This blog will explain what heart conditions require a pacemaker, how a pacemaker works, the benefits and advantages of a pacemaker, and answer the common question: Is pacemaker surgery dangerous? Understanding these aspects can help patients make informed decisions about their heart health.
Synopsis
What Heart Conditions Require a Pacemaker?
Many heart-related issues can necessitate a pacemaker. Here are some of the most common conditions:
-
Bradycardia (slow heartbeat): When the heart beats too slowly, it can’t pump enough blood, leading to fatigue, dizziness, or fainting.
-
Heart block or AV block: This occurs when electrical signals between the heart’s chambers are delayed or blocked, disrupting rhythm.
-
Tachy-Brady Syndrome: Characterised by alternating fast and slow heartbeats, this syndrome can cause symptoms ranging from palpitations to dizziness.
-
Heart failure: In some cases, pacemakers help coordinate heart contractions to improve pumping efficiency.
-
SA node dysfunction: The sinoatrial node is the natural pacemaker of the heart; when damaged, an artificial pacemaker may be required.
-
Post-heart attack recovery: Damage from a heart attack can disrupt electrical pathways, leading to arrhythmias.
-
Drug-induced heart rhythm issues: Certain medications can slow or disrupt heart rhythms, necessitating pacemaker support.
-
Congenital heart rhythm disorders: Some patients are born with electrical system abnormalities requiring pacing.
If you experience irregular heartbeats, palpitations, or unexplained fatigue, it is vital to consult a cardiologist at Manipal Hospitals, Kharadi for expert evaluation.
How Does a Pacemaker Work?
Understanding how a pacemaker works helps demystify the procedure and its benefits. The device is implanted just beneath the skin near the collarbone, close to the heart. It consists of a pulse generator and leads (wires) that connect to the heart muscle.
-
The pacemaker continuously monitors your heart rhythm.
-
It sends mild electrical impulses only when necessary, a process known as on-demand pacing.
-
These impulses stimulate the heart to maintain a steady, normal rhythm.
-
The device adjusts the pacing based on the body’s needs, such as during exercise or rest.
This tiny device ensures your heart beats at the right pace, improving blood flow and oxygen delivery to vital organs. Some patients find it helpful to see a diagram illustrating the placement and functioning of the pacemaker for better understanding.
Is Pacemaker Surgery Dangerous?
Many patients worry about the risks involved in pacemaker implantation. The good news is that pacemaker surgery is generally safe and considered a minor, low-risk procedure.
-
The operation is performed under local anaesthesia.
-
It usually takes about an hour and involves making a small incision near the collarbone.
-
Most patients recover quickly, often going home the same day or after an overnight stay.
-
Complications are rare, especially when the procedure is performed by experienced cardiologists.
At Manipal Hospitals, Kharadi, highly skilled heart specialists use advanced technology and follow strict safety protocols to ensure a smooth and successful pacemaker implantation.
Benefits and Advantages of a Pacemaker
The benefits of a pacemaker extend well beyond regulating the heartbeat. Here are some key advantages of a pacemaker:
-
Restores normal heart rhythm: Corrects slow or irregular heartbeats to normal levels.
-
Prevents fatigue and fainting spells: By maintaining an adequate heart rate, it reduces symptoms of dizziness and weakness.
-
Improves blood and oxygen supply: Ensures vital organs receive sufficient oxygenated blood.
-
Allows an active lifestyle: Patients regain the ability to perform daily and physical activities without fear.
-
Reduces the risk of stroke or heart failure: By improving heart function, the chances of complications decrease.
-
Enhances survival rates in high-risk patients: Particularly beneficial for those with severe rhythm disorders or heart disease.

When Should You Consider Pacemaker Implantation?
Certain symptoms may indicate the need for a pacemaker:
-
Dizziness or fatigue without an obvious cause.
-
Chest pain or discomfort.
-
Fainting or near-fainting episodes (syncope).
-
Shortness of breath or difficulty exercising.
To diagnose the need for a pacemaker, your doctor may recommend:
-
Electrocardiogram (ECG) to record electrical activity.
-
Treadmill Test (TMT) or stress test to observe heart function during exercise.
-
Echocardiogram to assess heart structure and function.
-
Angiography to check for blockages.
-
MRI or CT scan if further imaging is required.
Only a cardiologist can determine if pacemaker implantation is the appropriate treatment.
