Question

In the case of an artificial pacemaker, the electrode is inserted into
A. Right ventricle
B. Right auricle
C. Left ventricle
D. Left auricle
E. Both (A) and (B)

Answer 1

A cardiac pacemaker or also known as an artificial pacemaker, is a medical device that generates electrical impulses delivered by electrodes to cause the heart muscle chambers to contract and therefore pump blood. The electrical conduction system of the heart is monitored by the pacemaker. Simply it is an electrical device that measures the variations and rhythms of the heart with electrical stimulation. The battery of the pacemaker lasts for an average of 6 to 7 years.

Complete answer: The maintenance of the adequate heart rate because of the natural pacemaker that is not sufficient when there is a block is the primary purpose of the pacemaker. A specific type of pacemaker called a defibrillator combines pacemaker and defibrillator functions in a single implantable device. The pacemaker cannot sense the input signals for some time when there is a predetermined time of impulse.
When the pacemaker is implanted inside the skin under the clavicle it involves the transvenous placing of one or more electrodes within the right ventricle chamber of the heart. The procedure is performed by the incision of a suitable vein into which the electrode lead is inserted and passed along the vein, through the valve of the heart, until positioned in the chamber. The passage of the electrode lead is facilitated by a fluoroscopy procedure that enables the physician to detect. The opposite end of the electrode is connected to the pacemaker generator when there is satisfactory lodgement of confirmation.
A power device, lithium battery, sensing amplifier that contains the electrical manifestation of the heartbeats occurring naturally are sensed with electrodes by the hermetically sealed device called the pacemaker generator.
Hence, the correct option is (A) Right ventricle

Note: To attempt to mimic nature by utilizing various inputs that produce the parameters used for the rate-responsive pacemaker for the QT interval periods is the major advancement function of the pacemaker.
