Permanent Pacemaker Implant Procedure
A pacemaker is an electrical charged medical device which your surgeon implants under your skin to help managed irregular heartbeats (arrhythmia). Particularly for those whose heart rate beats too slow. The pacemaker is a pocket-size watch that intrinsic heart rhythm and provide electrical stimulation when indicate. Implanting a pacemaker requires a surgical procedure.
Two types of Pacemakers of arrhythmias
1. A heartbeat that’s too fast known as tachycardia.
2. A heartbeat that’s too slow known as bradycardia.
Some people have a special type of pacemaker called biventricular pacemaker, or bent. People with severe heart failure needs bivent pacemaker, A bivent make two sides of heartbeat sync. This process is called Cardiac Resynchronization Therapy (CRT).
Why do I need a pacemaker?
You need a pacemaker if your heart is pumping too fast or too slow. In either case, your body does not get enough blood.
This can cause:
- Shortness of breath.
- Damage to vital organs.
- Eventual death.
A pacemaker regulates the body’s electrical system, which controls the body’s rhythm. with each heartbeat the electrical impulse travels from the top of your heart to bottom of the heart, signalling the heart muscles to contract.
A pacemaker also tracks the heartbeats of your heart. which will help your doctor to understand arrhythmia.
Why pacemaker is Implanted?
Pacemakers can also be implanted temporarily to control a certain type of problems. You may need a temporary pacemaker after your heart surgery or heart attack. Or the pacemaker can be implanted permanently to correct irregular heartbeats, in some people it helps to treat heart failure.
The heart is a muscle, with four chambers two on the left side and two on the right side. The upper and lower chambers work with hearts electrical system to keep your heart beating at an appropriate rate. An approximately in the adult the heartbeats 60 to 100 beats a minute.

Your heart electric system controls the heartbeats, begins with the sinus node at the top of the heart and spreading them to the bottom. causing it to pump the blood.
An implanted pacemaker does the same action of our natural electronic system. a pacemaker includes two partsPulse generator – This small container consists of an inbuilt battery and the electrical circuitry that regulates the rate of electrical pulses sent to your heart.Electrodes – One on the three flexible wire is placed into your heart chamber to deliver the electrical pulses to adjust your heart rate.
The pacemaker works only when it is needed when your heart is beating slow the pacemaker sends an electrical signal to your heart to correct the beat. Newer pacemakers have sensors which detect the motion of your body or the breathing rate, which send a signal to your heart to increase rate while exercising.
How the surgery is performed?
Pacemaker surgery usually takes one to two hours. A doctor will give aesthesia to numb the area incision site just below your collar bone. You’ll be awake during the procedure but drowsy.
A surgeon will make a small incision near your collar bone. They insert a small wire through your incision into a major vein. The leads are guided through a vein into your heart. An x-ray machine will help guide your surgeon through the process. Using a wire, a surgeon will attach an electrode to your heart’s ventricle. The other end of the wire is attached to the pulse generator. later the surgeon will implant the generator under your skin. The surgeon will close the incision with stitches.
If you are getting a biventricular pacemaker, the surgeon will attach a second lead to the right atrium and three lead to the left ventricle.
