Pacemakers, or pulse generators, are mechanical devices which are used to correct bradyarrhythmias (abnormally slow and/or irregular heart contractions). Demand pacemakers sense when the heart is sending its own impulses, and work only when the heart fails to beat, or on demand. Fixed-rate pacemakers send impulses to the heart and bring about a continuous steady rate.
