What Is An Ectopic Pacemaker
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
Heart rhythm: The heart rhythm is being generated in a different spot than usual (usually from the high right atrium in the sinus node). If your rate is normal & the rhythm is regular, it would have no significance and you wouldn't even know about it unless you have an ekg. The overall condition of your heart determines the significance, not the rhythm, per se. ...Read moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
