Typically used for conditions such as bradycardia, atrioventricular block, and heart failure, the pacemaker consists of a computerized pulse generator enclosed within a small metal container, and one or more cables called leads.
The computerized pulse generator is the source of the electrical signals that normalize the altered heart rhythm; the leads, on the other hand, are the connections that unite the generator to the heart and allow the transmission of signals.
The procedure for implanting a pacemaker into the human body is fairly simple and low-risk and requires no special preparation, other than complete fasting and post-surgery care by a family member.
