Question

What is endoscopy? Explain its techniques. What is an artificial pacemaker? Explain its technique?

Answer 1

Hint: The most basic function of the pacemaker is to monitor the natural electrical rhythm of the heart. The endoscopy is a nonsurgical procedure that can be used for examining the GIT of a person.

Complete answer:
In the method of endoscopy an optical fibre is used, which is inserted inside the body to take images of the part or organ. The optical fibre is attached to a camera as well as other surgicals. The images are observed using a monitor and accordingly the surgery can be performed. This is a non-invasive technique.
An artificial pacemaker is an instrument or device that is used in controlling the heart beat. Pacemaker is placed on SA node impairment. In some patients, a blockage in certain areas also affects the heartbeat and the impulse is not able to get conducted in a proper way. The artificial pacemaker uses a battery and generator. The battery is responsible for causing the generator to initiate pumping of the conduction of the heart impulses, which results in contraction of ventricles as well as production of heart beats.

Hence, the correct answer is option ()

Note: The implantation of a pacemaker never requires an open heart surgery. Medications are used before surgery for which local anesthesia is used.
The process of esophagogastroduodenoscopy (EGD) uses a small flexible endoscope that is inserted through the mouth and then advanced through the pharynx, esophagus, stomach, and duodenum to view the upper GIT.
