What Is a Pacemaker?
What is a Pacemaker?
A pacemaker is a small gadget that's positioned in the chest or abdomen to aid control atypical heart rhythms. This device uses electrical pulses to evoke the heart to beat at a normal rate.
Pacemakers are used to treat arrhythmias. Arrhythmias are problems with the rhythm of the heartbeat or the heart rate. During an arrhythmia, the heart can beat very fast, very slow, or with an inconsistent rhythm.
Tachycardia- A heartbeat that is very fast.
Bradycardia- A heartbeat that is very slow.
Some people need a special kind of pacemaker called a biventricular pacemaker, or bivent. If you have acute heart failure then you may need a bivent. A bivent makes the 2 sides of the heart beat in synchronization. This is known as cardiac resynchronization therapy (CRT).
During an arrhythmia, the heart may not be able to pump adequate blood to the body. This can lead to symptoms such as fatigue or tiredness, shortness of breath or losing consciousness. Severe arrhythmias can vandalize the body's crucial organs and may even cause loss of consciousness or death.
A pacemaker can relieve some arrhythmia symptoms, such as exhaustion and loss of consciousness. A pacemaker also can help a person who has abnormal heart rhythms restart a more vital lifestyle.
Perceiving the heart's electrical system
Your heart has its own inner electrical system that manages the rate and rhythm of your heartbeat. With every heartbeat, an electrical wave advances from the top of your heart to the bottom. As the signal proceeds, it causes the heart to constrict and pump blood.
Pacemakers also can scan and record your heart's electrical activity and heart rhythm. Newer pacemakers can screen your breathing rate, blood temperature, and other aspects. They also can alter your heart rate to changes in your activity.
Pacemakers can be short-term or permanent. To treat short-term heart problems, such as a sluggish heartbeat that's caused by a heart surgery, heart attack or an of medicine overdose, the temporary pacemakers are used.
Short- term or temporary pacemakers also are used during emergencies. They might be used till the time your doctor can implant a permanent pacemaker or till a temporary disorder goes away. If you have a temporary pacemaker, you will be accommodated in a hospital as long as the device is in place.
Permanent pacemakers are used to manage long-term heart rhythm disorders.
Experts also treat arrhythmias with another gadget called an implantable cardioverter defibrillator (ICD). An ICD is similar to a pacemaker. However, in addition to utilizing low-energy electrical pulses, an ICD also can utilize high-energy pulses to treat fatal arrhythmias.
Most pacemakers are very dependable and safe. They are smaller than a normal matchbox and weigh about twenty to fifty grams. A pacemaker is positioned just under your collar bone and will have one or more leads which are placed into your heart through a vein.
A pacemaker has a pulse generator - electronic circuit powered by a battery - and one or more electrode leads.
Single chamber pacemakers- are pacemakers with 1 lead
Dual chamber pacemakers- are pacemakers with 2 leads
Biventricular pacemakers – are pacemakers with 3 leads
Your surgeon will discuss the most appropriate type of pacemaker for you is and this will depend on the basis why you need to have one.
