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.
Pacemaker . It is a device helping heart beating at certain rates in very simple terms .
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....

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...
Fixed rate pacemaker. These are very old style pacemakers that pace regardless of the intrinsic rate of the heart. Almost all pacemakers are demand pacemakers that only pace when the heart rate gets below a set threshold with sensing. Demand pacemakers can sometimes be temporarily programmed to fixed mode with a magnet applied. Pacers near eol may revert to fixed. Read more...

What people need pacemakers?

HeartRhythm or block. The most common indicators for an implanted pacemaker are bradycardia (slow heart rate), tachycardia (fast heart rate) and heart block (when the heart stops beating for several seconds). Read more...
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's a cardiac pacemaker for?

Treating slow rhythm. A pacemaker keeps the heart rate above a certain limit, which is programmable. It cannot treat heart rates that are already too high. Dealing with fast rhythms requires a different approach. Read more...

What is the pacemaker's primary job?

Prevent bradycardia. Most pacemakers are are placed in order to treat excessively slow heart rate (bradycardia). When the heart rate falls below a certain level, the pacemaker is automatically activated at a rate set by the cardiologist. Read more...

What are heart pacemakers for?

Regulate heart rate. Most are placed for patients with too slow heart rates, some can deliver shocks (aicd) for patients with rapid heart beats. Rarely used to improve heart pumping function in patients with heart failure. Read more...

What is the pacemaker for the coronary arteries called?

Doesn't exist. There is no pacemaker for the coronary arteries. The pacemaker is part of an electrical system of the heart that controls the contraction of the heart. The coronary arteries, like other arteries are simply flexible tubes that respond to pressures of blood flow caused by the contraction of the heart. With an implanted pacemaker, the lead may run through a coronary sinus but the tip is on the heart. Read more...
Pacemaker. The coronary arteries are blood vessels and do not have a pacemaker. They react as do all other arteries but not to a pacemaking structure like the sinus node for the heart. Read more...

Please inform me, is the dual chamber pacemaker is contraindication with atrial fibrilation? What the best pacemaker for AF people? Better ICD or PPM?

Depends on AF?? Ask your doctor what kind of atrial fibrillation you have. If dealing with paroxysmal atrial fib. and your doctor recommended pacemaker then dual chamber pacemaker is better suitable for you. If dealing with persistent or chronic AF and you have indication for pacemaker then single chamber pacemaker. Also discuss the current medication regimen with your doctor as some medication can affect rhythm . Read more...
