Hint:-A pacemaker may be a small, battery-operated device which is implanted under the skin. There are 2 varieties of pacemakers used only in medical emergencies. They are: Transcutaneous pacemakers and transvenous pacemakers. They're not permanent pacemakers.
Complete answer:
A pacemaker could be a small device that's placed under the skin in your chest to assist control your heartbeat. It's wont to help your heart beat more regularly if you have got an irregular heartbeat (arrhythmia), particularly a slow one. Implanting a pacemaker in your chest requires surgical treatment.
Procedure: A tiny low incision (cut) is formed. Most often, the cut is on the left side (if you're right handed) of the chest below your collarbone. The pacemaker generator is then placed under the skin at this location. The generator might also be placed within the abdomen, but this is often less common. A replacement "leadless" pacemaker could be a self-contained unit that's implanted within the heart ventricle of the guts.
Using live x-rays to work out the world, the doctor puts the leads through the cut, into a vein, then into the guts. The leads are connected to the generator. The skin is closed with stitches. Most of the people come back within 1 day of the procedure.
There are two parts:
- a generator and wires (leads).
• The generator could be a small battery-powered unit.
• It produces the electrical impulses that stimulate your heart to beat.
• The generator is also implanted under your skin through atiny low incisions.
• The generator is connected to your heart through tiny wires that are implanted at the identical time.
• The impulses flow through these ends up in your heart and are timed to flow at regular intervals even as impulses from your heart's natural pacemaker would.
• Some pacemakers are external and temporary, not surgically implanted.
- It replaces the heart's defective natural pacemaker functions.
• The sinoatrial (SA) node or sinus node is the heart's natural pacemaker. It is a small mass of specialised cells within the top of the correct atrium (upper chamber of the heart). It produces the electrical impulses that cause your heart to beat.
• A chamber of the guts contracts when an electrical impulse or signal moves across it. For the center to beat properly, the signal must travel down a selected path to achieve the ventricles (the heart's lower chambers).
• When the heart's natural pacemaker is flawed, the heartbeat could also be too fast, too slow or irregular.
• Rhythm problems can also occur due to a blockage of your heart's electrical pathways.
• The pacemaker's generator sends electrical impulses to the guts to assist it pump properly. An electrode is placed next to the guts wall and little electrical charges travel through the wire to the center.
• Most pacemakers have a sensing mode that inhibits the pacemaker from sending impulses when the heartbeat is above a particular level. It allows the pacemaker to fireplace when the heartbeat is simply too slow. These are called demand pacemakers.
Thus, the right option is C.
Note:- This device senses when your heart is thrashing irregularly or too slowly. It sends a proof to your heart that creates your heart beat at the right pace.
Note: Pacemakers work only if needed. If your heartbeat is just too slow (bradycardia), the pacemaker sends electrical signals to your heart to correct the beat.
Also, newer pacemakers have sensors that detect body motion or breathing rate, which signal the pacemakers to extend pulse rate during exercise, as needed.
