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: 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....

Speed up heart: If your heart is beating too slow, a pacemaker sends a small electric shock to the heart making it beat faster. There is a batery and some electronic circuits which tell the pacemaker when your heart beats too slow.

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.

Are there contraindications with pacemakers?

Dr. Andrew Kaplan

No: Virtually no one is allergic to a pacemaker. There are really no contraindications to pacemaker implantation. Rarely, access to a blood vessel to place the lead into the heart is limited (for example, due to scarring and closure of both subclavian veins).
