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.... ...Read more

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

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. ...Read more

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

Rollercoaster: If the patient is not pacer dependent and has a rate responsive pacer and a normal otherwise pumping function, should be ok. If the patient has a fixed rate pacer and doesn't go faster, then the rollercoaster represents a risk to the patient should a rate increase be needed from the g force stresses of the coaster. ...Read more

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. ...Read more

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. ...Read more
