cognize body changes and help the heartbeat speed up or slow down to meet the bodys changing needs. It mimics a hearts natural function. Rate-responsive pacemakers also use sensors that monitor the changes in the body other than heart rate (such as motion, frequency of respiration, etc.) and increase or decrease the heart rate accordingly based on the programmed values set by a physician. For people whose heart rate does not increase when needed, rate-responsive pacing: 1. Provides people with a more appropriate heartbeat for their current activity.2. Allows people to perform more vigorous exercise.3. Allows people to perform ordinary, daily activities more effectively.4. Gives people a greater sense of well being in their day-to-day lives.Rate-responsive pacemakers vary the heart rate in response to the bodys needs and its programmed settings, similarly to how a healthy heart works. Such variations in pacing rate allow patients to better perform their everyday activities. A pacing system consists of the pacemaker, which is a small metal case that houses the battery and circuitry that power it, and the pacing lead. This lead is an insulated wire, connected to the pacemaker, which carries the electrical impulses from the pacemaker to the heart and relays information about the hearts natural activity back to the pacemaker. A pacemaker consists of the battery, the circuitry, and the connector block. The battery supplies the electrical energy for the pacemaker. The batteries are made of lithium and usually last for many years. The circuitry is like a small computer inside the pacemaker that transforms the energy from the battery into electrical pulses. The connector block is a transparent plastic connector, located on top of the pacemakers metal container, where the lead is attached to the pacemaker. A pacing lead is an insulated wire that is connected to a pacemaker. The lead carries the electrical impulse from the pacemaker ...
