Today, there are many kinds of pacemakers, including some that can correct tachyarrhythmias as well as brady- arrhythmias. Modern technology allows all these therapies to be delivered via a single electronic device. In some situations, there's an advantage to implanting two separate devices. Attached to the pulse generator are one or more insulated wires that can sense the heart's electrical activity and modify it by delivering impulses. These impulses either supplement or override the patient's own heart rate and rhythm.
Minor surgery can remove small areas where cells are abnormal.
This technique can sometimes be used when the precise area that's causing the arrhythmia has been identified. A pacemaker may be required afterward. In rare instances, open-heart surgery can be used to accomplish the tissue destruction. Today's electronic cardiac pacing devices are extremely sophisticated and very dependable. Your doctor and the manufacturer will provide specific information about your device as well as any necessary precautions.
