Bundle Branch Block Left Pacemaker
A person with left bundle branch block may require treatment with a pacemaker. Pacemakers are electronic devices that regulate the heart rate within a normal range.
Pacemakers require an electrical wire inserted into the heart, which is connected to an electronic device that generates electrical impulses that stimulate the heart. Most pacemakers are placed under the skin.
All pacemakers do two things:
- They sense the electrical signals from a normal heartbeat. As long as the heart is beating fast enough, nothing else happens.
- The pacemaker sends a tiny electrical impulse to stimulate the heart to beat when the heart is beating too slowly.
Some pacemakers can shock the heart when a dangerous rhythm occurs. These are called implantable defibrillators.
Home care includes:
- Wear a Medic Alert bracelet, showing that you have a pacemaker.
- Take acetaminophen for pain.
- Magnets should be kept away from the chest.
- The metal in a pacemaker may set off metal detectors in airport and other security stations. Keep your pacemaker wallet card with you at all times.
