Electrodes, Leads and Interface Problems
- 92 Downloads
A pacemaker lead is defined as: an insulated wire connecting an electrode to a pulse generator. The electrode is an uninsulated termination of the lead which is in direct contact with the heart. The site of contact, with all its electrical and electrochemical characteristic features, and its capability of delivering electric current into the excitable cardiac structures as well as of transmitting action potentials (QRS and/or P waves) in an opposite direction to the amplifier of the pacemaker, is called the pacemaker-heart interface.
