   What is a cardiac pacemaker?

   Can a pacemaker pace at a specific heart rate?

   • The first pacemakers could only pace at one specific heart rate. Whenever the patient's own natural heart rate dropped below that pre-set rate (for example, 70 beats per minute), the pacemaker would start to pace at that fixed rate. Newer technology allows for more specific responsiveness.

   How does a pacemaker work?

   • To place a pacemaker, a doctor inserts one or more wires into a major vein under or near the collarbone. The doctor uses X-ray images to guide the wires to the heart. One end of each wire attaches to the proper area in the heart. The other end connects to the part of the pacemaker that delivers electrical pulses.
