Pacemaker ! You Should Know All About It

The pacemaker is a small device with two parts a generator and wires.  It usually uses when your heart is not functioning properly. During the surgery, it placed under the skin in your chest to control your heartbeat. People need this for a variety of reasons mostly due to one of a group of conditions called arrhythmias, in which the heart’s rhythm is abnormal.

What is Pacemaker?


This is a medical device it produces electrical impulses which delivered by electrodes to contract the heart muscles and regulate the electrical conduction system of the heart.


What are the Types of Pacemaker?


There are two types of heart device such as:


Single Chamber:


The single pacemaker triggers the chambers of the heart and an internal defibrillator combination known as a cardioverter defibrillator. The standard type of pacemaker sends an electrical impulse via special wires which are attached to the heart. This replaces the signal sent by the heart, which is faulty in patients who need a pacemaker.


Dual Chamber:


The dual chamber pacemaker is the internal defibrillator combination (AICD), sends an electrical impulse to the heart to control the heart’s rate and rhythm, just as a standard pacemaker does. It can also deliver a “shock” to stop a “lethal rhythm,” a heart rhythm that does not allow the heart to effectively function.


The idea of the shock is the same as the “shock with paddles” that you may have seen on television. The pacemaker is attached to the heart with wires, the shock is much less powerful than what you may imagine. It is very painful and has been compared to being kicked in the chest by a mule.

What are the Risk Factors of Pacemaker?


There are some risk factors of heart device such as:


1. Infection


2. Allergic reaction during the procedure


3. Bruising, swelling, and bleeding at the generator site


4. Damage to your blood vessels or nerves near the pacemaker


5. Collapsed lung


How to Prepare Yourself for Using Pacemaker?


There are a few ways to prepare yourself:




In this noninvasive test, sensor pads with wires attached, called electrodes, are placed on your chest and sometimes your limbs to measure your heart’s electrical impulses. Your heart’s beating figures the type of irregular heartbeat you have these images show how your heart is functioning, and recorded pictures allow your doctor to measure the size and thickness of your heart muscle.


Holter Monitoring:


Holter monitor is also known as an ambulatory monitor, a Holter monitor records your heart rhythms for an entire 24-hour period. Wires on your chest go to a battery-operated recording device carried in your pocket or worn on a belt or shoulder strap.


Stress Test:


Some heart problems occur only during exercise. In a stress test, an electrocardiogram is taken before and immediately after walking on a treadmill or riding a stationary bike. Treadmill exercise tests can be done to evaluate your heart, including an oxygen consumption test that measures how much oxygen your body is using.


What are the Precautions of Pacemaker?


There are some precautions such as:


1. Mobile Phones:


It’s safe to talk on a mobile phone but avoid placing your cellphone directly over your heart device implantation site. When the mobile is turned on then the pacemaker gets misinterpret with the cellphone signal as a heartbeat and withhold pacing, producing symptoms, such as sudden fatigue.


2. Security Systems:


When passing through an airport metal detector won’t interfere with your device, although the metal in it may sound the alarm. Avoid leaning against a metal-detection system. If the security personnel insist on using a hand-held metal detector, ask them not to hold the device near your pacemaker.


3. Medical Equipment:


If a doctor is considering any medical procedure which involves intensive exposure to electromagnetic energy, tell him or her that you have a device.




In the above article, we have talked pacemaker and how it can be helpful to our heart. We have discussed its type, risk, and precautions. Usually, it used when your heart is not functioning appropriately. Your surgeon will fit this into your heart so that your heart will work effectively.
