How does the artificial pacemaker work?

Pacemaker: A pacemaker is an electronic device which uses a lead as an antenna to sense the heart's electrical activity. It uses the same lead(s) to deliver a small electrical impulse to the heart to make it contract if the heart isn't going as fast as the device was programmed to maintain. Pacemakers both sense heart activity and pace it to produce activity. They maintain heart rate. Other things too....

Pacemaker (Definition)

A pacemaker is a device which sends electrical signals to the heart triggering heartbeats when needed. There are many ways to implant and configure a pacemaker; it may beat the top chambers (atria), lower chambers (ventricles) or both. Some systems stimulate both the left and right ventricles together. Pacemakers generally treat abnormally slow heart rhythms and certain ...Read more

A patient with an artificial mitral valve and pacemaker leaving the hospital after 82 days, should they received life time treatment t of ampicillin?

A patient with an artificial mitral valve and pacemaker leaving the hospital after 82 days, should they received life time treatment t of ampicillin?

No: Long term prophylactic Ampicillin is not needed, but needs to get prophylaxis before specific procedures such as dental work or cystoscopey.

Benefits/risks of pacemaker if >90?

Benefits/risks of pacemaker if >90?

Small risk-big bene: If a pacemaker is indicated, age is completely irrelevant. The vast majority of people who need and get pacemakers are elderly. It doesn't matter if you're >100. The procedure is minor and done under local anesthetic with minimal risk. If you're symptomatic from a rhythm disturbance corrected by a pacemaker, you will feel much better with it and there's not reason not to proceed.

What are the risks of riding rollercoasters for a person with pacemaker?

None: There are no risks unless they come very close to a powerful magnet which I do not think happens while you're riding a roller coaster. Even if you did however, nothing bad will happen and as soon as you walk away from the magnet, things go back to normal.

What is a pacemaker?

What is a pacemaker?

Heart device.: A cardiac pacemaker is a device that is implanted in the chest to permanently regulate heartbeat rhythms. The pacemaker monitors the heartbeat to make sure it is not beating too slowly, and when necessary transmits electric pulses to the heart to increase the heartbeat pace. Pacemakers are periodically replaced every several years when the battery runs out.

What are pacemakers?

What are pacemakers?

Speed up heart: If your heart is beating too slow, a pacemaker sends a small electric shock to the heart making it beat faster. There is a batery and some electronic circuits which tell the pacemaker when your heart beats too slow.

How to test a pacemaker?

Pacemaker clinic: You need to go to pacemaker clinic at a hospital where they will "interogate" it. You cannot do it by yourself.

How does a pacemaker work?

How does a pacemaker work?

Artificial pacemaker: Artificial (implantable) pacemakers are mostly regulated by a sensor that recognizes motion. It's similar to the sensor that changes your phone/ipads display from portrait to landscape, based on the direction of the device. There are other sensors, such as ones that measure the density of blood in the heart and chest motion (simulating breathing). Get your routine pacemaker maintenance checks.

Who should use pacemakers?

Who should use pacemakers?

HeartRhythm or block: Pacemakers are most commonly necessary for patients with bradycardia- slow heart rate, tachycardia - fast heart rate, and heart block - when the heart stops beating for several seconds.

What are fixed pacemakers?

Fixed rate: I assume you mean fixed rate pacemakers. We don't use them anymore. The very earliest pacemakers just fired at whatever rate you set them, once a second if you set the rate to 60. That lead to chaos if the patient's inherent heart rate was not always real slow. So they made pacemaker's which sense normal beats and only fire if the rate gets slow. They are inhibited when a heartbeat is sensed.

How are pacemakers placed?

How are pacemakers placed?

Minor surgical proce: Pacemakers are placed in a cardiac cath or surgical suite with the visual guidance of fluoroscopy (x-ray visualization). A pacing lead is placed into the heart after access to a vein in the arm, groin, neck, chest is obtained. Specific electrical parameters of the lead are checked, then the lead attached to a pacemaker often embedded in the upper chest wall, where small incision is made.

How do pacemakers function?

How do pacemakers function?

Pacemaker: When the heart rate slows down to a certain level the the pacer senses this then puts out an electrical impulse to cause the heart to contract.

What people need pacemakers?

What people need pacemakers?

Slow heart rate: The typical reason to get a pacemaker is slow heart rate *hr), say, below 40 beats a minute. Some people get pacemakers because their hr won't increase with exercise. The most common reason is atrial fibrillation, which can often lead to slow hr. Slow hr causes fatigue or out of breath with exertion or passing out. Some people get special pacemakers to improve heart function if the heart is weak.
