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

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. ...Read more

What are fixed pacemakers?

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. ...Read more

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. ...Read more

What causes pacemakers to work?

What causes pacemakers to work?

Pacemakers: A pacemaker is a battery driven device. It is actually a small computer. Some of its functions are like a radio receiver, its pacing function is just delivering a tiny shock to the heart. A defibrillator delivers a bigger shock to the heart. ...Read more
