PACEMAKER INSERTION
A pacemaker is a device inserted to help control and regulate the heartbeat for those who have an irregular heartbeat (arrhythmia).
WHY DO I NEED IT?
The heart has an electrical system to keep your heart beating at an appropriate rate. When the heart muscle is damaged by a heart attack, medications or a specific genetic defect, your heart’s rhythm may become abnormal. This is known as arrhythmia. In these cases, your cardiologist may suggest inserting a pacemaker to mimic your heart’s natural electrical system to ensure that the heartbeat does not become unstable (sick sinus or tachy-brady syndrome) or too dangerously slow (bradycardia or heart block).
HOW IS IT DONE?
To insert a pacemaker, you will likely be awake, but relaxed. Local anaesthesia is used to numb the area of incisions. A small incision is made under the left shoulder bone. Through this incision, two special wires called ‘pacemaker leads’ are inserted into the major vein that flows from the left shoulder directly into the heart. These leads are then connected to the pacemaker itself, which is a small device about as big as a large watch. This device is then buried underneath your skin. This then restores the communication between the chambers of the heart and also prevents your heart from beating too slowly.
WHAT ABOUT AFTERWARDS?
After the insertion procedure, you will need to stay in the hospital for observation for a day or two. During this time, Dr van Rensburg will program your pacemaker for your needs. While you recover, your cardiologist may advise against the vigorous activity.
Having a pacemaker should improve symptoms caused by slow heartbeat, such as fatigue, lightheadedness and fainting. After your initial follow-up appointment, you will require a yearly check-up to check on your device. Batteries usually only need replacement at 10-15 years.
