What Element Is Used In Pacemakers
Several answers: There are several answers to this. From the cardiologist, ep doctor or ct surgeon. First one meets the criteria for pacing. Next several companies have their reps hold the device with them and hospitals hold them. We use routine venous sheaths to access the vein and flexible wires to guide wires to the heart then through techniques position the leads and secure device or pacemaker to them.

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
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 moreSee 1 more doctor answer
Pacemakers: Pacemakers are used to sense the heartbeat and if no heartbeat is detected, an electrical impulse to stimulate the heart is provided. Therefore, components of a pacemaker are 1. Sensor 2. Power supply to deliver an electrical impulse 3. Leads that connect the body of pacemaker to the heart. Current day pacemakers are very small, almost size of a large coin. Circuitry is inside a titanium can. Read moreSee 1 more doctor answer

My grandfather is in his 80's and he will be having the battery on his pacemaker replaced. Are their any major risks involved?
Nuclear pacemakers: To the best of my knowledge nuclear powered pacemakers have not been used for many years. They were made in the mid 1970s and only a few hundred were implanted. Read more
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
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.

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
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. 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
