Mechanical & structure activities of pacemaker
In the modern world, several treatment options have emerged as a result of heart disease research. Some of these treatment concepts are discussed below.
Pacemaker:-
Located on the right atrium wall of the heart, a small part composed of specialized cardiac muscles and controlled by the tonic nervous system, which spreads electrical waves and creates pulses and maintains the rhythm of the pulse, is called a pacemaker. The sino-atrial node is the pacemaker in the human heart. A computerized electrical device implanted in the body to create and control the heartbeat when it is useless or sick is also called a pacemaker. Therefore, one of the two types of pacemakers is the sino-atrial node (SA node) which is an integral part of the heart called the natural pacemaker. familiar; The other is the mechanical pacemaker, which monitors the ailing natural pacemaker. The function of natural pacemaker is explained under cardiac conduction. Here the mechanical pacemaker operation is discussed in explaining the concept of heart disease treatment.

Mechanical Pacemaker Activities :-
A small special device placed under the skin on the chest or above is called a pacemaker to restore and control the normal pulse rate by generating electrical waves in the sick and weak heart. To keep the body healthy, strong and active, it is very important to maintain and control the health of the heart. The first step in measuring the health of the heart is to check the heart rate. If the heartbeat is slower or faster than normal or irregular, that is, if there is an abnormal beat, it is called arrhythmia. In such a condition, people may become tired, have shortness of breath or become pale. Severe arrhythmias can damage vital organs, cause a person to faint or even die. The use of a pacemaker can prevent all types of arrhythmias, and keep you healthy for the rest of your life. Two American scientists, William Chardack and Wilson Greatbatch, invented the implantable pacemaker in 1966.
Structure of mechanical pacemaker:-
A pacemaker consists of a lithium battery, computerized generator and several wires with sensors on top. The sensors are called electrodes. The battery supplies power to the generator. The battery and generator are enclosed in a thin metal box. Do not connect the generator to the heart with cables. The electrodes detect the heart's electrical activity and transmit it through wires to a generator.
A pacemaker consists of 1-3 insulated wires. According to the type of entry of the lead into the different chambers of the heart with the lead of the pacemaker, there are 3 types of pacemakers described below.
3. Single-chamber pacemaker (Single-chamber pacemaker) This type of pacemaker has a wire or lead that carries electrical waves from the generator to only the right atrium (atrium) of the heart or one of the ventricles.
2. Dual-chamber pacemaker type of pacemaker consists of two wires (leads) which carry electrical charge from the generator to the two chambers of the ventricles ie the right atrium.
3. Triple-chamber pacemaker: This type of pacemaker has three wires (leads).
One of the generators power the right atrium, the other the right ventricle, and the other the left ventricle
carries the wave. It is placed in the heart of very weak heart muscle (otherwise risk of heart failure remains) In this case, the pacemaker improves blood flow by improving the contractility of the ventricles.
