Pacemaker Insertion for the Heart

What is a Pacemaker?

A pacemaker has 3 parts;

  • A pulse generator
  • One or more leads
  • A tiny electrode on each lead

The lead signals the heart to beat when the rate is irregular or too slow.  The pulse generator is about the size of a matchbox and encased in a metal case; it has an electric circuit, with a miniature computer and a battery. It sends signals via the lead to the heart.  The pacemaker lead(s) may be placed in one chamber (right ventricle) or two chambers of the heart (both right ventricle and right atrium)

What is a Pacemaker Insertion

There are some people who have an abnormal or irregular heart rate that needs a pacemaker. When the heart rate is too slow or too fast, it can affect the function of the heart and cause a variety of symptoms. A pacemaker is a small electronic device that is surgically implanted on the left side just below the collar bone. Once inserted, a pacemaker can regulate the heart rate and prevent it from becoming dangerously slow. A pacemaker may also be used to treat fainting spells (syncope), congestive heart failure and hypertrophic cardiomyopathy.

Leadless Pacemaker

Unlike the conventional pacemaker which uses batteries and wires, patients can now opt for something more advanced like the leadless pacemaker. This device has a built-in battery and electrode to monitor the patient’s heart rhythm and stimulates their heart when needed. On the contrary of the standard pacemakers, this piece will reside entirely in the right ventricle of the heart. To place this pacemaker, a catheter that contains the device is passed through a small hole in the groin and attach in into the heart. For most people, the procedure is done under local anaesthetic. The patients will be given some numbing medicine for the groin. The entire process will take about 1 hour and in some cases, less time. When it is over, patients may have to wait in a recovery room until the doctor is certain they are ready for discharge.

What are the Benefits of A Leadless Pacemaker?

  • Avoidance of a surgical scar under the skin where the pacemaker sits
  • Avoidance of problems with lead placement and reduction in risk of infections
  • It is 93% smaller than conventional pacemakers, about the size of a large vitamin capsule
